Noah didn't have this problem. Faced with a crisis of truly biblical proportions, he was not afforded any choice about which animals to protect from the coming flood. Instead, Genesis reports, God instructed Noah to bring every kind of animal onto the ark “to keep the species alive on the face of all the earth.”[FN1] *1172 Noah obeyed, the passengers of the ark survived the flood, and “every beast” returned to inhabit the earth.[FN2]

The Endangered Species Act (ESA) seems to embody the same idea. The ESA protects all species from extinction. Grizzly bears and kangaroo rats, alligators and salamanders, bald eagles and black-capped vireos--all are entitled to the same protection from government and private action once they are determined to be endangered or threatened with extinction. There are a few exceptions, but generally the ESA does not allow society to decide that one bird is more important than another, or that we will save one animal but not another.

Yet there is a competing biblical metaphor for the ESA. Judges, legislators, professors, and others have described the law as “playing God.”[FN3] The “God Squad” is the popular term for the Endangered Species Committee, the seven federal officials charged by the ESA with determining which federal projects will proceed despite the likely extinctions they will leave in their paths.[FN4] Other parts of the ESA provide numerous opportunities for enforcement authorities and interested parties to prefer some species over others. And some advocates of amending the ESA explicitly endorse a system that allows us to decide which species will live and which species will die. *1173 The choice between biblical metaphors lies at the heart of the current debate over the future of the ESA. Once viewed as too popular to criticize, the ESA has become the focal point of intense controversy. On the one hand, critics of the law see it as a threat to private property unrivaled in environmental law. On the other hand, defenders of the ESA insist that its existing provisions are inadequate to the task of protecting biodiversity threatened by rampant habitat destruction. Thus “[e]ndangered species have been used as a whipping post for the left and the right, to no one's advantage.”[FN5] Most of the dispute has centered on the ESA's ban on activities on private property that would harm the habitat of an endangered species, but the prohibition against federal government activities that jeopardize the existence of a species and the very process of listing a species as endangered or threatened have sparked numerous controversies themselves.[FN6]

Three recent events illustrate the debate over the ESA and the relevance of the competing biblical metaphors. First, the 104th Congress subjected the ESA to its most intensive critique since a nearly unanimous Congress and President Nixon approved the law in 1973. Early in 1995, a special House task force held a series of hearings in parts of the country where the ESA is often viewed as the enemy of the people.[FN7] Six bills designed *1174 to make the law more palatable to those who encounter its requirements followed from those hearings.[FN8] The outcry from environmentalists, the Clinton Administration, and others doomed each of the bills before they reached the floor of the House or the Senate. The episode repeated itself in 1997, when efforts to exempt flood control projects from the ESA prompted accusations that the same forces were trying once again to gut the Act.[FN9] Throughout each debate, the rhetoric has betrayed the desires of the speaker. Environmentalists, the Clinton Administration, and other supporters of the Act spoke of bald eagles, grizzly bears, whooping cranes, and alligators. Landowners, western House Republicans, and other critics of the ESA referred to kangaroo rats, fairy shrimp, ambersnails, tiger beetles, and of course, the snail darter.[FN10] *1175 The second event was the publication of Noah's Choice: The Future of Endangered Species, the excellent discussion of endangered species and the Endangered Species Act written by Charles Mann and Mark Plummer.[FN11] The book demonstrates, if nothing else, why The New York Times Magazine, Smithsonian, and The Atlantic are more widely read than your favorite law review. Mann and Plummer have written for these publications (and then some), and they succeed in telling the story of endangered species in a way that resembles a mystery novel more than a technical scientific journal. Their book was published one month after the beginning of the 104th Congress, and the proponents of rewriting the ESA often credited Noah's Choice as a source of intellectual inspiration.[FN12] Mann and Plummer see the ESA as the embodiment of the “Noah Principle,” scientists' term for the human obligation to protect all species from whatever ecological disasters that come their way. Faced with a conflict between protecting endangered species and any other human aspiration, the endangered species always wins. Mann and Plummer argue that it is impossible to protect all *1176 endangered wildlife and plants because we lack the resources and the will to do so. They further contend that continued allegiance to the Noah Principle prevents a real discussion of the choices we must make. Mann and Plummer thus propose an alternative system that would allow society to choose between endangered species and other concerns (e.g., whooping cranes or oil fields), or between one endangered species and another (e.g., whooping cranes or black-capped vireos). In other words, they prefer a law in which we play God instead of Noah. God can choose who lives and who dies; Noah could not.[FN13]

Third, and most surprisingly, the 104th Congress heard a series of religious arguments in favor of the protection of biodiversity. Interior Secretary Bruce Babbitt has argued that “religious values remain at the heart of the Endangered Species Act.”[FN14] He recognizes the utilitarian arguments for preserving species, but he prefers “the moral and spiritual imperative that there may be a higher purpose inherent in creation, one demanding our respect and our stewardship quite apart from whether a particular species is or ever will be of material use to mankind.”[FN15] Or consider the position of the Evangelical Environmental Network (EEN), an evangelical Protestant group whose recent lobbying and nationwide advertising campaign regarding the ESA gained widespread attention.[FN16] The EEN *1177 believes that “[a] species should be preserved because it has been created by God.”[FN17] Thus the EEN “opposes any Congressional action that would weaken, hamper, reduce or end the protection, recovery and preservation of God's creatures, including their habitats, especially as accomplished under the Endangered Species Act.”[FN18] Likewise, the Coalition on Environment and Jewish Life (COEJL) emphasizes that “[e]ndangered species are God's creatures.”[FN19]

In each instance, the story of Noah has served as a justification for the protection of endangered species. Secretary Babbitt has delivered speeches and written articles defending the ESA as an imitation of Noah's example.[FN20] EEN has relied on the story of Noah as the centerpiece of its campaign supporting the ESA.[FN21] COEJL has sponsored “Operation Noah” in an effort to defend “God's endangered creatures.”[FN22] Each group defends the ESA as the modern way by which we imitate Noah, much to the dismay of those favoring more sweeping changes in the law.[FN23] *1178 The idea of amending the ESA to give more protection to the species we care most about-- bald eagles, grizzly bears, and the like--and less protection to species with less appeal is abhorrent to ecologists. Most opponents of the law approach the issue gingerly, and even the most sweeping bills to amend the ESA avoid any direct consideration of the value of particular species. But the effort to treat all species equally faces a dilemma. Choices between species appear inevitable because of the huge number of species and the limited amount of resources available to protect them. Choices between species occur in the implementation of the law, notwithstanding the image of the ESA as prohibiting discrimination between species. Yet the story of Noah suggests that choices among species are impermissible. In other words, when confronted with the task of choosing among species, we have to, we do, but we shouldn't.

Part I of this Article explains why choosing among species is inevitable. The large number of species that are endangered, the limited amount of resources for preserving biodiversity, and the competing demands presented by other societal problems make it impossible to protect every species. Part II describes how the implementation of the ESA acknowledges this inevitability by preferring some species over others in a variety of contexts. Part III examines how plants and animals provide invaluable utilitarian benefits ranging from food to medicine to tourism. Nonetheless, Mann and Plummer and other critics of the existing law are extremely effective in demonstrating that such utilitarian arguments do not justify treating all species equally. Instead, the case for protecting all species must depend on moral, religious or ethical arguments. Part IV considers the implications of Noah's example--and the biblical context in which it occurs--along with the theological, constitutional, moral, and legal arguments against reliance upon Noah as the basis for the ESA. I conclude that Noah *1179 provides a compelling case for protecting all endangered species regardless of whether one believes that a flood actually occurred or whether one finds the scriptures authoritative. That appears to be impossible, though, so Part V contemplates how Noah would have made choices among species if he was forced to do so. My guess is that Noah would have tried to save the most species and the most different kinds of species possible. While Noah avoided making any such choices, the fact that we are already choosing among species today demands that we take greater care in determining how we do so. This approach does not answer many of the hard questions about how we should protect biodiversity or whether the ESA is working, but Noah's example does show that the goals of the ESA remain sound.

I. THE INEVITABILITY OF CHOOSING AMONG SPECIES

The multiple threats to endangered species lead to one conclusion: not all species can be saved. The threshold issue is to define what constitutes a “species.” In Noah's Choice, Mann and Plummer chart the evolution of scientific thinking from classifying the animals that were carried on the ark, to the taxonomical work of eighteenth century Swedish botanist Carl Linnaeus, to Darwin's theories, and finally to the current understanding of species as “special groups of organisms that breed together.”[FN24] That technical debate has significant ramifications for the protections of endangered “species.” As the definition of “species” becomes more and more precise, the number of species increases, and more animals or plants will be eligible to stake a claim for protection. The scientific debates have spilled over into the law as parties dispute the appropriate classification of a species.[FN25] As one author recently *1180 put it, “the classification of animals, like that of any group of significant objects, is apt to tell as much about the classifiers as about the classified.”[FN26] With this in mind, some reformers have targeted the ESA's protection of “subspecies” as unjustified.[FN27] Such a change would have dramatic consequences: the northern spotted owl, for example, is a subspecies of the spotted owl, and would no longer receive the ESA's protection.[FN28]

Thus defined, the first problem confronting any effort to prevent a species from going extinct is the sheer number of *1181 species present in the United States and throughout the world. Mann and Plummer present a staggering number of statistics: 1.8 million species have been discovered, but drawing on the type of scientific research that identified 1200 different kinds of beetles in a single tree, scientists estimate that there may be as many as 100 million different species on the earth today.[FN29] Other sources provide similar numbers.[FN30] And those numbers do not include subspecies. Furthermore, the total number of species itself is far less important than the number of species that are endangered. Scientists disagree on that number. At one end of the spectrum, Harvard biologist Edward O. Wilson estimates that 27,000 species are becoming extinct each year; at the other end, the World Conservation Monitoring Centre counts only 1237 extinctions since the year 1600.[FN31] The uncertainty is compounded by our inability to know when an extinction occurs.[FN32]

*1182 Determining the number of species in danger of extinction would assist in planning for the effort to protect such species, but again, that number is less important to the current political debate than the number of species listed as endangered or threatened under the ESA. The protections of the ESA extend to species that are formally listed as “endangered” (i.e., “in danger of extinction throughout all or a significant portion of its range”) or “threatened” (i.e., “likely to become endangered. . . within the foreseeable future”).[FN33] The list includes 896 endangered species and 230 threatened species.[FN34] But the list could grow much longer. Over 20,000 species were proposed for listing before the ESA was two years old.[FN35] The United States Fish & Wildlife Service (FWS) has formally identified 173 species as candidates for listing.[FN36] Another 10,000 may deserve further consideration.[FN37]

The huge (albeit uncertain) number of species combined with environmentally destructive human activities and natural events results in many endangered species, which in turn yields a growing list of such species. As the number of listed species grows, the cost of protecting endangered species grows as well. For example, the Karner blue butterfly lives in fields of lupine, a flower that flourished throughout the east and *1183 midwest during the nineteenth century but which has become much less common today. The destruction of the lupine fields has left scattered populations of the Karner blue butterfly in a line of states ranging from New Hampshire to Minnesota. The FWS listed the Karner blue as endangered in 1992.[FN38] Buying the land necessary to protect the Karner blues that live near Albany, New York alone would cost at least $150 million.[FN39] Protecting Karner blues elsewhere, as would be necessary to prevent a catastrophic event from wiping out a single population of the species, would cost “billions of dollars.”[FN40]

A similar controversy has surrounded two songbirds (the black-capped vireo and the golden-cheeked warbler), the Barton springs salamander, and several cave-dwelling insects in the Hill Country west of Austin, Texas. Efforts have long been underway to establish a system of preserves for those species amidst the rapid urban sprawl of Austin.[FN41] Estimates of the cost of protecting the Hill Country species range from hundreds of millions of dollars (to fully implement the biologists' initial plan) to $86 million (to purchase the land to be set aside *1184 under a 1990 plan).[FN42] Those estimates only include the cost of purchasing the land; ongoing maintenance costs and the other costs of establishing a system of preserves would drive the total sum higher. Moreover, the effect of the regulatory demands of the ESA adds over $9000 per acre to the cost of development in the area.[FN43]

There are many other examples. The recovery plan for endangered salmon will cost hundreds of millions dollars annually.[FN44] California gnatcatchers live on undeveloped coastal land north of Los Angeles--land worth as much as $200,000 per lot, so that establishing reserves for the gnatcatcher could cost billions of dollars.[FN45] The San Bernadino County Medical Center Replacement *1185 Facility spent over $3 million to mitigate its impact on the Delhi Sands Flower-Loving Fly.[FN46] Protecting the Stephens kangaroo rat might cost $50 million.[FN47] And these examples only show the cost of protecting a few species, not protecting all species. In Mann and Plummer's words, “protecting all species would be a fantastically costly enterprise.”[FN48]

“Fantastically costly” lacks the precision required by an accounting firm, but it provides a fair description of the bottom-line cost of protecting the increasing number of endangered species. The other side of the ledger shows that we have limited resources available for endangered species protection and many competing demands to use our limited resources for other purposes. Mann and Plummer complain of the “scandalous unwillingness of Congress to back this lofty mission with significant budget outlays.”[FN49] The appropriations numbers prove their point.

All parts of the enforcement of the ESA are affected by the limited funds available. The FWS does not have nearly enough resources to process all of the candidates proposed for the list. It would have taken the seven agency listing experts 500 years to review all of the 20,000 candidates proposed for the list in the first two years that the ESA was in effect.[FN50] The situation has not improved much since then. Funding for the FWS increased “slightly faster than the pace of listings for native U.S. *1186 species” between 1974 and 1989.[FN51] Even by 1993, however, it was estimated that it would take another forty-three years to list just those species already under consideration.[FN52] Thus, the agency has cited its “limited budget” as the reason for not listing certain species earlier,[FN53] and the courts have agreed that it is “impossible” for the FWS to list all deserving species because of the insufficient funding.[FN54] Accordingly, “when the [FWS] undertakes one listing activity, it inevitably forgoes another.”[FN55]

Likewise, the ESA's provision empowering the government to acquire the habitat of endangered species “is woefully underfunded and shows no signs of changing in that respect.”[FN56] The *1187 cooperative grants from the federal government to help states preserve federally protected species receive one quarter of the appropriations that would be necessary to fund each agreement.[FN57] Recovery plans suffer from a similar lack of funding. The 306 existing recovery plans would cost nearly $900 million to complete, but the FWS requested only $84 million in fiscal year 1995 to implement them.[FN58] Likewise, each Habitat Conservation Plan (HCP) “requires considerable expense,” though usually most of the cost is paid by affected private parties.[FN59] The current federal budget for spending on endangered species programs pales in comparison to these needs, and calls for dramatically increased funding are likely to go unheeded. The budget for endangered species programs fluctuated during the 104th Congress, which cut funding one year and then raised it *1188 the next.[FN60] When Secretary Babbitt refers to “an era of constrained budgets”[FN61] and President Clinton announces that “the era of big government is over,”[FN62] even the most favorable scenario will not produce the kind of money needed to preserve all endangered species.

But the problem is not the lack of resources per se. It is conceivable (though still not entirely certain) that we could implement every plan to protect every endangered species if we spent the entire $1.5 trillion annual federal budget on endangered species protection. Obviously we have other priorities. Sometimes those priorities appear frivolous. The 1991 FWS budget for endangered species was matched by the money spent on Domino's pizza in Washington, D.C., that year.[FN63] In other instances our priorities reflect our affluent society. The endangered species living in the Hill Country west of Austin have conflicted with the building of single-family homes, apartment buildings, fast-food restaurants, convenience stores, gas stations, light industry, supermarkets, and countless other projects.[FN64] The habitat of the Karner blue butterfly in Albany was replaced by residential subdivisions, a racetrack, the Albany *1189 Country Club, a state office complex, a Niagara Mohawk power substation, four lanes of Interstate Highway 90, the State University of New York at Albany, and the Crossgates Mall.[FN65] The development of hot springs into commercial resorts has helped nine species of plants become endangered in California.[FN66] The famous snail darter almost defeated the Tellico Dam.[FN67]

Protecting endangered species habitat instead of building another 7-Eleven presents an easy choice. But Mann and Plummer worry about the cumulative effects of such decisions:

We do not need one more convenience store. But that doesn't mean we can easily do without all convenience stores. . . . [A]dopt a policy of no more stores and people will be out of work and unable to find the things they need. Then shut down the banks, the golf courses, the shopping malls, the parking lots, and the gas stations and watch the costs to people's hopes and dreams rise to ever more unacceptable heights.[FN68]

Of course, people live without golf courses and shopping malls in most parts of the world, so the debate about protecting the habitat of endangered species may reduce to a debate about the kind of society in which we want to live.[FN69] Such decisions must be made by the citizens of Albany, Austin, the Pacific Northwest, and most other areas throughout the United *1190 States. More than 200 million people live near a species that is listed as endangered or threatened;[FN70] so even though endangered species cluster in certain areas,[FN71] one day many of us may have to choose whether to preserve land for endangered species habitat or to use it for some other purpose.

The hardest cases occur when the preservation of an endangered bird or animal comes at the cost of forgoing some other critical endeavor. Protecting the Oklahoma habitat of the American burying beetle has blocked the construction of a highway connecting a Native American community to the nearest hospital on the other side of the mountains; the beetle may also destroy the coal mining jobs of poor families.[FN72] The residents of Wilton, New York, must live with mosquitoes during the summer because the easiest way of controlling them would harm the Karner blue butterfly.[FN73] The butterfly also lives on a camp that the Boy Scouts want to sell to fund programs for urban children, thereby preventing the sale.[FN74] The *1191 black-capped vireo delayed the redesign of a dangerous Texas highway where two dozen people were killed in recent years.[FN75] And those are only the choices recorded in Noah's Choice.[FN76] Once we move outside our borders into developing countries that struggle to feed their people, the required choices between endangered wildlife and basic human needs become more frequent and more frightening.

Nor is the conflict limited to the use of any particular piece of land. It is also between using scarce funds to protect endangered species and using those funds for other purposes. Endangered species programs are not the only worthwhile endeavors facing declining government appropriations. Environmental pollution, crime prevention, inadequate education, poverty, and a host of other needs compete with endangered species for money and attention.[FN77] To cite but one drastic example, one county official has recounted how five of his colleagues left a meeting crying when they could not fund an immunization program for infants at a time when they were required to spend millions for endangered *1192 species preservation.[FN78] Necessarily, then, any decision to pay more for endangered species means that we pay a little less for everything else. That is the inevitable choice identified in Noah's Choice.[FN79]

The result is that we can probably save any species, but we cannot save every species.[FN80] The successful efforts to save the American bald eagle demonstrate that we have the ability to preserve a species when we commit the resources necessary to do so. But the bald eagle is only one species. Other birds have gone extinct in the United States despite the ESA, and many *1193 more birds (and mammals, and insects, and fish and plants) remain endangered. We lack the resources and the willingness to take the steps that are required to assure the recovery of all of those species. There are even times when the actions necessary to protect one endangered species actually harm another endangered species.[FN81] If those limits exist, then “we must choose.”[FN82]

II. THE CURRENT PRACTICE OF CHOOSING AMONG SPECIES

The common image of the ESA is that it prohibits any choices among species. Mann and Plummer, for example, complain that the law prevents any balancing between endangered species and other societal needs.[FN83] In their view, the ESA dictates that all endangered species must be treated equally, and that all endangered species are more important than everything else.

They exaggerate. To be sure, the protections of the ESA extend to any species that is endangered or threatened by extinction. Yet the ESA itself makes some distinctions among species. Plants and insects receive less protection than mammals, fish, birds, and reptiles. The controversial prohibition on “taking” endangered species applies to fish or wildlife, not to plants.[FN84] Instead, endangered plants on federal land cannot be removed, maliciously damaged, or destroyed; the protection of endangered plants on other land is subject to the strictures of state law.[FN85] Insects receive less than complete protection, too. *1194 Subspecies of insects are not protected by the ESA.[FN86] The Secretary of the Interior may decide not to preserve an endangered insect species that “constitute[s] a pest whose protection under the [ESA] would present an overwhelming and overriding risk to man.”[FN87]

Nor does the ESA protect all animals, birds, or fish. The ESA offers no help to deer and cardinals and dolphins because they are not endangered or threatened with extinction; therefore, a landowner can “take” a deer without threat of federal sanction. More importantly, the ESA protects only those species that have been formally listed as endangered or threatened.[FN88] No species were listed during most of 1995 and the beginning of 1996 because Congress and President Clinton approved a temporary moratorium on the listing of any additional species.[FN89] The moratorium serves as a reminder that the ESA operates to protect species only once they are formally listed, no matter how endangered they may be in fact.

Other parts of the ESA establish priorities among species. The FWS's guidelines for listing species and for recovery plans give greatest priority to protecting species in danger of extinction, second priority to maintaining the status quo, and lowest priority to actually promoting the recovery of a species.[FN90] Federal *1195 funds for state endangered species programs are distributed in part based on the relative urgency of the threat to the survival of the species that will benefit from such funds.[FN91] The protection that a species receives also depends in part on the likely impact of human economic activities. When establishing recovery plans, the agency must give priority to species most likely to benefit from such a plan, particularly if a species conflicts with an economic development project.[FN92] When deciding whether or not to designate critical habitat for a species, the FWS must determine that the benefits that such a designation would provide to a species outweigh the social and economic benefits of not designating any critical habitat.[FN93]

None of those criteria make any value judgments about the intrinsic worth of any particular species. Those provisions of the ESA may result in some species receiving less protection than others, but that judgment is made based on the impact on the species, not the qualities of the species itself. For example, the critical habitat designation can be influenced by the fact that all of the habitat lies in prospective residential lots in Orange County, but the ESA does not ask whether such habitat is for an endangered kangaroo rat or an endangered bald eagle.

The actual implementation of the ESA reveals a different story. Tulane Professor Oliver Houck has described how each aspect of the ESA--listing, designating critical habitat, consultations to avoid jeopardizing a species, the God Squad exemption process, recovery plans, and the prohibition on takings--is applied in a manner that affords the government broad discretion in enforcing the law. Indeed, Houck concludes that the ESA “has, in effect, been substantially amended through regulations and practice, transforming it from an act of specific requirements into a more discretionary permit system.”[FN94] With such discretion, the government (and others) can choose among species. And they do, to the frustration of environmentalists (who favor strict enforcement of the law) and developers (who complain that they do not know the rules of the game) alike.

Consider the ways in which we make choices among species already. First, the FWS must decide the order in which species will be considered for listing. The limited resources and *1196 threats of congressional reprisals tempt the agency to list species that are noncontroversial, either because they are popular with the public or because their protection will not require great sacrifices. The first species that the agency listed after Congress passed the ESA in 1973 were three types of Australian kangaroos, none of which would conflict with projects in the United States.[FN95] The agency strained to avoid listing the snail darter precisely because it feared the fish would undermine public support for the ESA itself.[FN96] It resisted listing the northern spotted owl as endangered, doing so only after a court order, and then using a threatened (instead of endangered) listing to minimize the impact in some areas.[FN97] It may have had a similar strategy in mind when it designated the California red-legged frog as threatened in the first addition to the list after the moratorium expired.[FN98] Frogs have some popular appeal, albeit not as great as grizzly bears and bald eagles, but this particular frog was memorialized by Mark Twain as the Celebrated Jumping Frog of Calaveras County.[FN99] Likewise, the 1996 listing of seventy-five Hawaiian plants was criticized as “perfectly calculated for an election year” because it would not adversely affect many people.[FN100] By contrast, very few insects *1197 were listed during the 1980s, probably because there were no invertebrate specialists at the FWS's headquarters in Washington and because field office staff resist such listings.[FN101] The bigger picture shows that today there are 331 mammals and 274 birds listed as endangered or threatened, but only forty-one insects, twenty-three snails, and nineteen crustaceans.[FN102]

The FWS enjoys even greater discretion once a species is listed. It must decide whether to designate critical habitat for a species. It must also conclude how much money to devote to developing and implementing a recovery plan for a particular species. Additionally, it must resolve which habitats it can purchase under the section 5 land acquisition program and which habitat conservation plans to encourage and to approve. Lastly, the FWS (or the God Squad) must determine which projects are subject to section 7's prohibition on federal actions that would jeopardize the continued existence of the species.

Experience shows that the agency makes some of those decisions with an eye toward the species that is at stake. Indeed, one writer has indicated that the FWS follows “an informal hierarchy in which mammals are often given priority over birds, birds over cold-blooded vertebrates, and cold-blooded vertebrates over invertebrates--with plants trailing behind them all.”103 Government spending patterns support that claim. A recent study identified a “spending preference to the ‘higher’ animals in the following order: mammal-bird-fish-reptile-amphibian.”[FN104] Plants do not even make that list.[FN105] More specifically, *1198 federal and state agencies spent at least $10 million between 1989 and 1991 on each of the following ten species: the bald eagle, the northern spotted owl, the Florida scrub jay, the West Indian manatee, the red-cockaded woodpecker, the Florida panther, the grizzly bear, the least Bell's vireo, the American peregrine falcon, and the whooping crane.[FN106] Over $30 million was spent on the bald eagle alone. Cumulatively, the top ten species account for over half of all spending on endangered species preservation. And almost all of the species in the top ten are large, popular mammals or birds. By contrast, less than $10,000 was spent on such species as the Texas blind salamander, the sand skink, and the Alabama cave fish, even though they are much more genetically distinct or much more in danger of extinction.[FN107]

The money provided to state endangered species programs pursuant to ESA section 6 shows a similar bias. The FWS recently announced that it had awarded $2.7 million for the acquisition of habitat necessary to satisfy HCPs in four states.[FN108] The announcement noted the funds would be used to protect the bald eagle, the peregrine falcon, sea turtles, and a number of songbirds. While nearly one hundred other endangered species would be helped by the money distributed to the states, the FWS press release neglected to identify any of those presumably less popular species.
*1199 The same pattern can be seen in the application of the section 7 prohibition on federal projects that would jeopardize the continued existence of a species. Professor Houck's study of ninety-nine instances in which the FWS formally determined that a federal project would jeopardize a species indicates that the species most frequently at risk were as follows:

Only five plants, one butterfly, and no other insect were found to be in jeopardy by one of these projects.109 The bias also shows up in the designation of critical habitat.[FN110]

Private environmental groups, state and local governments, and other interested parties face the same considerations--though they are under no obligation even to pretend to treat all species equally. The symbol of the World Wildlife Fund is the giant panda, not the kangaroo rat. Audubon magazine has referred “ecocelebrities”--like the bald eagle, the whooping crane, and the gray wolf-- that dominate the news.[FN111] One supporter of increased funding for endangered species suggests that “[t]he few high-profile mammals and birds we *1200 have pushed to the very brink of extinction may be able to survive on voluntary contributions.”[FN112] At each point, the money committed to protecting endangered species plays a powerful role in determining how much protection that species gets.

The favoritism for the most popular species is not uniform. The species protected by the first seven HCPs approved by the Interior Department include the mission blue butterfly, the callippe silverspot butterfly, the Coachella Valley fringe-toed lizard, the Stephens' kangaroo rat, the desert tortoise, the San Joaquin kit fox, and the valley elderberry long-horned beetle.[FN113] The species for which recovery plans have been developed seem almost inversely related to the prominence of the species: recovery plans exist for 78% of endangered and threatened snails but only 12% of endangered or threatened mammals.[FN114] Likewise, the species covered by the most expensive recovery plans include the blunt-nosed leopard lizard, the swamp pink, and other species unknown to the public at large.[FN115]

Other factors besides charisma must explain why some species are preferred more than others. The most obvious additional variable is the presence of an economic activity that would be threatened by the protection of an endangered species. This cuts both ways. Developers, economic interests, and many government officials may want to minimize the legal obligations imposed by the ESA. Environmentalists, by contrast, often seize upon the ESA's powerful mandates to block a project that threatens broader environmental values. Besides these economic conflicts, preferences among species may depend upon mere awareness that the species exists and is endangered *1201 and upon the perceived utilitarian value of the species.

The formal explanation for choices among species lies in the express policy of the FWS itself. The agency “recognizes that it is necessary to assign priorities to listing, delisting, reclassification, and recovery actions in order to make the most appropriate use of the limited resources available to implement the [ESA].”[FN116] Therefore, in 1983 the FWS issued regulations that detail the priorities to be followed when deciding which species should be listed and which species should receive the greatest assistance.[FN117] The regulations give greatest priority to the species that are most in danger, as measured by both the magnitude and the immediacy of the threat to the species.[FN118] A secondary priority accrues to species with the greatest taxonomic distinctiveness--in other words, species that possess the most unique characteristics.[FN119] The decision as to which recovery plans to implement is also weighted to favor those species *1202 whose preservation would conflict with economic activities, in an effort to resolve such conflicts as soon as possible.[FN120] The priorities are not absolute, but are instead intended to be applied flexibly.[FN121]

The formal preferences of the FWS and the apparent practical preference for the most popular species both disprove the claim that the ESA prevents any choices among species. The statute does not specifically direct the government how to allocate its limited resources when deciding which of many deserving species to list, what land to buy, or what enforcement actions to pursue. Thus the inflexible law portrayed by the statute's critics conflicts with the discretion exercised by the government when actually implementing the law. The ESA has permitted choices between species; it has allowed us to play God.

III. THE UTILITARIAN REASONS FOR NOT CHOOSING AMONG SPECIES

Therein lies the paradox: we cannot protect every species, we distinguish among species in practice, but we are unwilling to write the statute to guide such decisions or even to acknowledge that they are being made. Even to suggest that some species are more valuable and deserving of more protection than others is anathema to ecologists. That, however, may be what Congress and the public want. The Congress that enacted the ESA in 1973 was thinking primarily (if not exclusively) of the most charismatic species.[FN122] Most writers presume greater support for *1203 protecting bald eagles than spiders.[FN123] Zygmunt Plater has observed that “[e]ndangered species had the good fortune to be represented by such mediagenic figures as the bald eagle, the polar bear, whales, and whooping cranes, all of which were sentimentally appealing, fairly remote from market considerations affecting most people, and dramatic or beautiful.”[FN124] The studies *1204 of Yale Professor Stephen Kellert have yielded similar conclusions.[FN125] As two critics of the ESA have written:

[Another] flaw with the ESA is that it does not discriminate between the protection afforded a bear or a beetle. When the average American considers the issue of endangered species, he thinks of eagles and manatees. These are the species that attract support: the warm and cuddly animals, the gentle woodland creatures. However, with the exception of plants, the act gives the same protection to all endangered species. Recognizing how this can create public relations problems, one National Park Service manual says that “from an educational standpoint, popular plants and animals can be used as a spoonful of sugar to make the medicine go down.” It's a classic case of bait and switch: financial and political clout are gathered for fuzzy, likable mammals like pandas, but the law is then applied to anything that crawls.[FN126] Such complaints have become increasingly common as frustration with the strictures of the ESA led some to ask the 104th Congress why we protect all species alike.[FN127]

*1205 Three bills introduced in 1995 would permit such choices. Senator Gorton, for example, refused to assume that all species are equally important; rather, he asserted that “we need [a government] official to explain to us why the species is important.”[FN128] Thus, his bill (like the other two) would require the Secretary of the Interior to determine the appropriate conservation goal for each individual species. The Secretary would consider a number of factors to make that determination, including the biological significance of the species and all of the direct and indirect economic and social impacts of protecting the species.[FN129] If those factors do not support efforts to assure *1206 the complete recovery of a particular species, then the ESA would not require the recovery of that species.[FN130] The end result would be that some species would receive greater protection than others.

Such a system would have parallels elsewhere in environmental law. Federal statutes afford some environmental amenities greater protection than others. The list of permissible activities varies greatly in Yosemite National Park and in unreserved public land managed by the Bureau of Land Management. The Clean Water Act allows states to decide that some rivers and lakes must be suitable for swimming while other rivers and lakes need only be suitable for industrial uses.[FN131] Superfund sites do not need to be cleaned up to the identical level of purity.[FN132]

The implication of these proposals is that choosing among species may be difficult, but it is not as impossible as many believe. This claim is crucial. If choosing among species is inevitable (as I argued in Part I), and if we choose in practice already (as described in Part II), then perhaps we should openly allow such choices. There are only two arguments against a system that expressly chooses among species. We could continue to hide the choices that we make among species because we are afraid of the consequences of a public admission that we are making such choices. I am skeptical of such concerns about candor, for reasons I explain below.[FN133] But the second argument *1207 against a system that chooses among species deserves more consideration. If, in fact, there is a good reason for trying to protect every species, then our practice of preferring some species to others becomes problematic. It becomes necessary, then, to analyze the reasons why we care about protecting endangered species. The utilitarian justifications for the preservation of species do not support the equal protection of all species, but there are other, non-utilitarian reasons for treating all species alike.

A. Utilitarian Justifications for Protecting All Species

Congress stated that the ESA is necessary because “species of fish, wildlife, and plants are of esthetic, ecological, educational, historical, recreational, and scientific value to the Nation and its people.”[FN134] These are all utilitarian justifications for protecting endangered species of wildlife and plants. The benefits are impressive:

(1) Food: People eat animals and plants, and not much else (Cheetos excepted). This gives tasty or nutritious animals and plants real economic value. Mann and Plummer cite the white-tailed deer, the example used by William Temple Hornaday nearly a century ago.[FN135] Two million deer, each providing ten dollars of meat, result in a resource worth $20 million dollars per year.[FN136] Today “the constant infusion of genes from wild plant species adds approximately $1 billion per year to U.S. agricultural production.”[FN137] Producing food provides jobs for millions of Americans. If an edible species disappears, so does the food and jobs it provides. Thus, some members of the Pacific Northwest's salmon industry are among the ESA's biggest supporters.[FN138]

*1208 (2) Medicine: Plants and animals are an important source of drugs and other medical treatments. Numerous exotic plants have yielded life-saving drugs.[FN139] Scientists are examining numerous plants as they search for a cure for AIDS.[FN140] Animals, fish, amphibians and insects possess medical value as well.[FN141] And we are only beginning to study most species to learn if they possess any medical value.[FN142]

*1209 (3) Aesthetics & tourism: People enjoy visiting, photographing, painting, and just looking at wildlife. The aesthetic value of a beautiful animal or plant often produces a tangible economic value in the form of ecotourism. Grizzly bears attract millions of people to Yellowstone and Glacier National Parks annually. Whales bring visitors to California, Hawaii, and New England. Tourists travel to numerous areas to visit bald eagles. These visits produce substantial economic value. The FWS recently reported that the seventy-six million Americans who watched, photographed and fed birds and other wildlife in 1991 spent $18.1 billion on those activities.[FN143] Another report calculated that birdwatching alone is a $15 billion dollar business annually.[FN144] These general economic benefits also result from endangered species in particular. Whooping cranes and other wildlife generate $5 million annually to the economy of the area surrounding the Aransas National Wildlife Refuge in Texas.[FN145] A rancher in the Texas Hill Country earned $14,000 from groups that came to see the endangered golden-cheeked warbler and black-capped vireo.[FN146] Large numbers of boaters, divers, snorkelers, and swimmers visit the west coast of Florida to see an endangered manatee--indeed, the number has become so large that the FWS recently found it necessary to create a new sanctuary to further protect the manatees from the people who want to see them.[FN147] The aesthetic appeal of *1210 many endangered species extends to those who never see such a species in the wild, or who never will.[FN148]

(4) Ecological assistance: Animals and plants also provide benefits to the ecosystem as a whole, benefits that indirectly help human society. Mann and Plummer note that

species play a vital role in such essentials as maintaining the quality of the atmosphere (forests act as air filters), controlling the climate (vegetation takes in carbon dioxide from the atmosphere), regulating freshwater supplies (trees absorb and release water), generating soil (microorganisms crumble rock), and disposing of wastes (American burying beetles inter dead mice).[FN149]

Birds have long been valued for eating troublesome insects and the seeds of unwanted weeds.[FN150] The endangered Alabama beach mouse protects coastal housing from hurricanes.[FN151] The list of natural services also includes flood and drought control, pollination of crops, protection from ultraviolet rays, and the dispersal of seeds and nutrients.[FN152] Perhaps we could secure these benefits from other sources, but we would pay far more than the free use of the natural resources we depend upon now.

(5) The “canary in the mine”: The loss of one species may serve as an early warning that the rest of the ecosystem is in danger. “Endangered species are the ‘miners' canaries' for the health of something larger, which we have not yet attempted to protect in a more holistic way.”[FN153] Many environmentalists, for *1211 example, view the decline of the northern spotted owl as a sign of the decline of the old growth forests in which it lives.[FN154] The dangers of the pesticide DDT were first learned from the decline of the bald eagle.[FN155] We ignore such warnings at our peril.

* * *
There are many other utilitarian services provided by a wide range of plant and animal species.[FN156] Collectively, such benefits supply a powerful case for protecting the environment.

B. Limits of Utilitarian Justifications for Protecting All Species

These utilitarian benefits do not, however, prove that we cannot live without any particular species. The justifications for protecting endangered species usually make an unspoken move from why we need to protect endangered species to why we need to protect each endangered species. Here again, Noah's Choice is devastatingly effective in undermining the ecological orthodoxy that all species are of equal value. Mann and Plummer begin by turning each justification around to show that it is possible to distinguish the value of different species. People depend upon about “fifteen to twenty” species for most of their food, but even considering that another 3,000 plant species may be a source of food, that still leaves many species with no nutritional value for humans.[FN157] Efforts to identify plants and animals with medicinal uses have identified far more “useless” species than helpful ones.[FN158] Beauty may be in the eye of the beholder, but if we are willing to designate certain areas like the Grand Canyon or the Everglades *1212 as worthy of special protection because of their unique features, why not make such distinctions among plants and animals? Tourists make such choices daily: whatever abstract arguments can be made about their aesthetic appeal, Yellowstone National Park attracts far more visitors than the Maplewood Municipal Park a few blocks from my home. Plants are necessary to produce organic carbon molecules, but “because so many species produce these molecules in so many different ways, huge numbers would have to vanish before the world experienced a failure of photosynthesis.”[FN159] Moreover, scientists are increasingly able to measure the contributions of individual species in stabilizing the ecosystem and other species.[FN160] Many of the species discussed at length in Noah's Choice do not possess any of these utilitarian values.[FN161]

Mann and Plummer further contend that what we don't know about biodiversity could just as easily cut against protecting a species as it could counsel for it. Is the unknown monkey in Amazon rainforest the source of the cure for AIDS, or is it the bearer of the next AIDS virus? If we don't know, they ask, why should we assume the former instead of the latter? Mann and Plummer go so far to suggest that “treating biodiversity in the way environmental activists would like to treat chemicals would suggest automatically banning species we don't know about.”[FN162] They admit the idea is ludicrous, but they insist that arguments based on ignorance cannot carry the day.

The canary-in-the-mine justification is much harder to dismiss. Mann and Plummer note that the interdependence of ecosystems supports protecting the individual components of *1213 ecosystems,[FN163] but they devote less attention to this argument than to the other utilitarian arguments that they canvass.[FN164] This omission is odd because many others have emphasized the canary-in-the-mine concern during the recent debate over the ESA. The FWS's pamphlet on the ESA spends more time discussing the canary-in-the-mine argument than any other rationale for saving endangered species.[FN165] Numerous speakers at the 1995 hearings on the ESA relied on the argument.[FN166] The analogy has been offered in many other forums as well.[FN167]

*1214 Mann and Plummer acknowledge the existence of so-called “keystone” species--such as beavers and mangroves--that the rest of an ecosystem depends upon. They conclude, however, that such species “are rare and are overwhelmed by the legions of the fungible.”[FN168] Fair enough, but that misses the point. Keystone species are different from “indicator” species--those species whose health tracks the health of the ecosystem in which they live.[FN169] The early warning signal of ecosystem decline is sent by any declining indicator species, not just those species that are most important to the ecosystem. That presents the best utilitarian argument for protecting many otherwise unremarkable species.

Nonetheless, the canary-in-the-mine argument does not explain why we need to protect a species once it sounds the warning about the ecosystem. If the species lacks any of the other utilitarian values, or if the ecosystem (or an adequate approximation) can be preserved without this one species, or if there is no utilitarian reason for saving the ecosystem itself, then there is no utilitarian reason to save the species whose decline alerted us to the problem. As J.B. Ruhl has written:

*1215 The problem with the indicator species approach biologically is that it leads to a static view of ecosystems. The fact that a species acts as an indicator of the health of an ecosystem does not necessarily mean that the species's health is essential to the health of the ecosystem, or even that the ecosystem for which it serves as an indicator is a particularly desirable one in terms of the species community and ecosystem functions.[FN170]

Moreover, as Mark Sagoff argues, “[i]f ecosystems are unstructured, transitory, and accidental in nature, it would seem to follow that no general economic or utilitarian grounds exist for protecting them from change.”[FN171] Even Zygmunt Plater, perhaps the greatest champion of the canary-in-the-mine argument, acknowledges that it does not justify the protection of every endangered species.[FN172] We may want to save ecosystems, but for different reasons than why we want to protect individual species--reasons that do not require us to protect every species.[FN173]

In short, “biodiversity as a whole has overwhelming utilitarian value, but most individual species do not.”[FN174] If the *1216 stated purpose of the ESA is to preserve the utilitarian value of endangered species, and if that value varies from species to species, then we should decide which species we are willing to protect and which we are not. The resource constraints detailed above appear to make such choices imperative, and that approach is precisely what many recommend.[FN175] But if Congress was wrong--if the utilitarian arguments fail to exhaust our reasons for preserving biodiversity-- then choices among species become problematic.

IV. PLAYING NOAH

A host of writers have advanced theories establishing moral, ethical, and religious duties to preserve all species.[FN176] Their theories are different in many respects--simply because there is no consensus about morality, ethics, or religion--but they share one thing in common. Any of these theories would confound a system that allows us to choose to protect some species but not others. One of them--the claim that the biblical story of Noah compels us to provide legal protection to all species--deserves special consideration. That ancient story occupies a unique place in our consciousness, whether or not one believes that it is true. *1217 The tale of Noah and his ark resonates with young children and government officials alike, it continues to inspire book titles (e.g., Noah's Choice) and fundraising campaigns to protect wildlife; and it has played an unexpected role in the recent debate over the future of the ESA. For these reasons, I want to focus on the lessons that supporters of the ESA have learned from Noah, and how critics of the law have responded.

The story of Noah appears in chapters six through nine of the book of Genesis. Genesis tells us that God regretted the creation of humanity because people had become wicked and evil, so God decided to remove all people and all other living things from the face of the earth. Noah, however, was a righteous man who found favor before God, and God decided to spare him and his family. God instructed Noah to build an ark--a prototype houseboat--that he and his family could use to survive the impending flood. Additionally, God directed Noah “to bring into the ark two of all living creatures, male and female, to keep them alive with you. Two of every kind of bird, of every kind of animal and every kind of creature that moves along the ground will come to you to be kept alive.”[FN177] Noah obeyed God's command. The promised flood destroyed all living things on the earth except for the occupants of the ark. Then the waters receded, the ark struck dry land, and God told Noah to “[b]ring out every kind of living creature that is with you--the birds, the animals, and all the creatures that move along the ground--so they can multiply on the earth and be fruitful and increase in number upon it.”[FN178] Finally, God promised Noah, his descendants, and every other living creature that he would never destroy the earth again.

That story features prominently in the defenses of the ESA offered by Secretary Babbitt, EEN and other Christian and Jewish groups, and even secular proponents of biodiversity. God “did not specify that Noah should limit the ark to two charismatic species, two good for hunting, two species that might provide some cure down the road, and, two that draw crowds to the city zoo.”[FN179] Noah invested much time, money, *1218 and resources in building the ark and collecting all of the species.[FN180] The resulting covenant between God and Noah “was made to protect the whole of creation, not for the exclusive use and disposition of mankind, but for the purposes of the Creator.”[FN181] Some have even suggested that the story implies that *1219 “God was more concerned about preserving animal species than sinful people.”[FN182] Moreover, the flood confronted by Noah has been compared to the flood of people and pollution that threatens biodiversity today.[FN183] In short, “Noah's ark was really the first Endangered Species Act.”[FN184]

*1220 Perhaps those advocating choices among species could not have anticipated the prominence that Noah would achieve in the debate over the ESA, thanks to Secretary Babbitt and EEN and others, but the story is not exactly new. We face a seemingly unsolvable dilemma if the story of Noah teaches the lessons suggested above. Imitating Noah means that we should preserve all species, but our limited resources prevent us from doing so. That dilemma could be avoided, though, if the objections to reliance on the story of Noah as a justification for extending legal protection to all species alike are persuasive.

There are three such objections. The first objection claims that the story of Noah fails to provide a religious or moral duty to protect all species. Noah's example allows for some uncertainty about whether he (and God) intended to protect all of the species that we recognize today, and the balance of the scriptural record indicates a more nuanced relationship between people and the world in which we live. The claim that Noah imposes a duty to protect all endangered species, however, remains sound. This is true regardless of the authority (if any) one attributes to Genesis because Noah also supports moral, nonreligious theories of species preservation. The second objection rejects reliance on Noah's example as the basis for creating a legal duty, and specifically the precise legal obligations imposed by the ESA. A legal duty to protect biodiversity *1221 seems inevitable because of the pressures on species today, though the equivalence between the story of Noah and the ESA is much more debatable. The third objection contends that the religious and moral nature of the story makes it unconstitutional to rely on it as a justification for a law like the ESA. But a law based on Noah would probably survive constitutional attack, if for no other reason than the difficulty in distinguishing a statute protecting endangered species from other statutes allegedly based on purely moral concerns. In short, each of the concerns about relying on the story of Noah to justify the ESA's formal protection of all species alike merits serious attention, but I remain convinced that Noah's example teaches that the law should protect all endangered species alike.

A. The Religious or Moral Duty Established by the Story of Noah

The invocation of the story of Noah by Secretary Babbitt and other supporters of the ESA has prompted complaints from those who question the lessons of that story for the protection of endangered species. The easiest way out is to dismiss the authority of the scriptures, though even then Noah's example can support a moral argument for species preservation.[FN185] The task is trickier for opponents of the ESA who wish to remain faithful to the scriptural commands as they dispute the relevance of the story of Noah. Assume for a moment, therefore, that faithfulness to God includes a desire to follow Noah's example. That assumption notwithstanding, the conclusions that Secretary Babbitt and others have drawn from Noah's example have been challenged as contrary to the balance of the scriptural teachings on the environment.

To begin with, it is not clear that Noah understood species as we do today. The word that is sometimes translated “species” in Genesis is more often translated as “kind.”[FN186] The modern conception of species derives from the eighteenth century work of Carl Linnaeus, who constructed the elaborate scheme dividing the natural world into kingdoms, classes, orders, genuses, and species. [FN187] There is no evidence that Noah anticipated that classification scheme as he prepared to collect *1222 the animals for the ark. Indeed, we do not know what “kinds” of animals Noah saved: he might have used a broader test that admitted a pair of squirrels onto the ark but not a pair of each different type of squirrel, or he might have used a narrower test that admitted lots of different squirrels based on more refined characteristics than biologists rely upon today.

Whatever Noah's understanding of “species,” he made a few distinctions between them. Fish were seemingly left off the ark to fend for themselves, though a flood hardly presents a mortal threat to the survival of most fish.[FN188] Perhaps more significantly, more clean animals were brought on the ark than unclean animals,[FN189] a distinction that could suggest that different species possess different value. The apparent explanation for the extra numbers of each clean species appears in the next chapter of Genesis, where Noah used clean animals for an offering to God.[FN190]

Additionally, after Noah and his cargo survived the flood, God allowed people to eat meat for the first time--but only the meat of clean animals.[FN191] This episode offers some support for the utilitarian claim that species that are most useful for food (or for sacrifices) are most deserving of preservation efforts today. Moreover, literal adherence to Noah's example would require us to save only one mating pair of each species.[FN192] Such a two animal minimum would offer little solace to those *1223 concerned about the ESA, though, because it still acknowledges a duty to protect every species. Furthermore, the actions necessary to protect the last two members of a species are likely to be nearly as expensive and burdensome as preserving a larger number.

The fact remains, however, that Noah sought to preserve all “kinds” of animals by placing them on the ark, and the few qualifications on that effort were quite modest. Perhaps, though, the story was not meant to be normative. The flood was a one time occurrence; maybe Noah's actions were unique, too. There is no indication that Noah realized he was establishing a precedent. A related concern objects to the use of the story of Noah as a “proof text,” plucking a biblical teaching out of context to support a point it was never intended to make. Perhaps Robert Booth Fowler's observation that “it is hard to avoid the sense that some liberal Protestant environmentalists try much too hard to discern an ecological Bible” best summarizes this concern.[FN193] To be sure, there is no biblical verse that commands “thou shalt preserve every species on earth,” nor does species preservation figure prominently elsewhere in the scriptures. But to dismiss the story of Noah so readily ignores that God must have had a reason in commanding Noah to take every species onto the ark. Indeed, the story of Noah shows that God was concerned enough about the preservation of every species to require Noah to go to extraordinary lengths to save them. The rest of the scriptures offer no suggestion that God's interest in biodiversity has waned over time. The reason for Noah's burden would appear to apply equally to his descendants today. Moreover, to the extent that Noah was concerned about saving himself, not just the animals, it is possible that our fate is linked to the survival of the life around us, too.[FN194] Maybe we are in the same boat as Noah after all.

*1224 Those seeking to avoid a duty to protect every endangered species are more likely to turn to other parts of the scriptures. Genesis records that God entrusted man with dominion over the earth, a notoriously difficult passage for environmentalists.195 Genesis further directs man to “fill the earth and subdue it.”[FN196] Former Interior Secretary Manuel Lujan cited the dominion command to justify actions that could result in the loss of a species.[FN197] Representative Dannemeyer has complained that the ESA “has reversed” God's grant of dominion so that “[a]nimals today are more important than people.”[FN198] Representative Cooley has expressed his belief that “we are going against God” by protecting endangered species, adding that “maybe we might be the higher creatures of God's creation.”[FN199] *1225 Likewise, the head of the National Association of Evangelicals has worried that “[t]here is a certain pantheistic element in all this,” contrary to the biblical mandate.[FN200]

The gist of such statements is that people are more important than animals. One possible corollary of that assertion is that the value of each species is measured by its value to humans. But such an effort to justify choices among species conflicts with other biblical texts that indicate that all parts of creation have value to God independent of their utilitarian value.[FN201] In any event, while the superior position of people to other forms of life could influence the resolution of conflicts between humans and animals, it would not necessarily support distinctions between different kinds of non-human life. In other words, even though God may be most concerned about people, there is no scriptural evidence that God prefers some animals or birds to others. Indeed, the whole issue of the relative position of humans vis-à-vis the rest of the world--while exceptionally controversial in environmental and theological circles[FN202]--is a red herring when considering choices among endangered species. *1226 While balancing human needs versus the needs of biodiversity lies at the heart of current disputes over the ESA, the official position of the ESA is that the particular species at issue is irrelevant to the proper balance to be achieved.

There is a more basic problem, though, with such lines of argument. The dominion of which Genesis speaks should not be understood as a license for humans to do whatever they want to the world for whatever purpose they happen to have in mind. The word “dominion” is used elsewhere in the scriptures to refer to a peaceful rule designed to serve those living subject to it.[FN203] Conversely, those who exercise dominion in a way that serves only their own desires received harsh criticism.[FN204]

A better understanding of the implications of the dominion command of Genesis can be gleaned from three models presented in the biblical account. Dominion as kingship reflects the just, righteous rule that God expected of Israelite kings.[FN205] Dominion as servanthood imitates the way in which God provides for creation and the kind of rule that Jesus described in the New Testament.[FN206] Dominion as stewardship posits that *1227 God is the owner of creation who has asked us to serve as a trustee responsible for managing the earth on God's behalf.[FN207]

Stewardship is the prevalent model. God's status as the owner of creation is confirmed throughout the scriptures and elsewhere: Genesis reports that God created all species,[FN208] other biblical passages refer to the resulting creation (including wildlife) as belonging to God,[FN209] and references to all endangered species as “God's creatures” occur frequently in the debate over the ESA.[FN210] Like other trustees, people should not act *1228 to further their own best interests, but instead to best serve the owner. And God--the owner--values each part of creation.[FN211] God also values the diversity of creation.[FN212] Moreover, the biblical account anticipates a world that is to thrive in its own right and that will eventually be redeemed.[FN213] This stewardship model is further supported by the instruction given by *1229 God to Adam in Genesis to tend the earth and to “keep” it.[FN214] The stewards of creation, therefore, must treat the creation in a manner that reflects the value and purpose that God places on the creation.

The proponents of the ESA and the protection of biodiversity emphasize such understandings of dominion.[FN215] Indeed, a recent monograph written by two evangelical scholars asserts that the duty to protect endangered species flows from a variety of biblical themes.[FN216] Christians should care for endangered species, they say, “because non-human creatures are valuable in themselves as creations of a good and loving God, because we as God's image-bearers are given the responsibility of keeping creation, and because such care is a fitting response of gratitude for the good gifts God provides.”[FN217] In short, “we have *1230 a prima facie duty to protect and preserve non-human species.”[FN218]

The broader scriptural context, therefore, supports the duty to preserve biodiversity implicit in the story of Noah. But even when they are properly understood, the biblical commands--especially the command to exercise dominion--conflict with ethical theories that treat people and other species in an identical fashion. The claim of “speciesism”--a discriminatory preference for the human species over all other species--has been leveled against Christian environmentalists and others who acknowledge a higher ethical position for humanity.[FN219] The balance between human needs and the needs of animals will be set differently by someone seeking to adhere to the biblical account and by someone seeking to treat all species (including humans) alike. The dilemma that those advocating animal rights face when choosing between the survival of a human baby or a dog is not a dilemma at all according to the teachings of Genesis.[FN220] Yet it is not true that the balance between human needs and animal needs taught by Genesis always tips in favor of human needs. The story of Noah expending tremendous time and resources “to keep the species alive on the face of all the earth” is simply the most dramatic example of the scriptural imperative for preserving biodiversity. The creation story, God's command to Adam to “keep” the land, and numerous passages throughout the whole Bible provide similar evidence of the duty to act in a manner that protects all of creation, even if human desires must be sacrificed in the process.

All of this assumes a desire to imitate Noah because of religious conviction. Of course, one could possess a religious conviction that adheres to the general teachings of scripture while questioning whether the story of Noah and the ark is literally true. Efforts to imagine how all of the world's animals fit on the ark have occupied writers for centuries, with no obvious answer immediately *1231 at hand.[FN221] But the lessons of the story of Noah do not depend upon whether it records an historic event or not. There must be a reason why Genesis includes the story, and while that reason may not be clear, it does not appear to change depending upon the actual occurrence of the flood and Noah's response to it.

For those who deny the authority of the scriptures, the story of Noah does not instill a religious obligation to preserve all species. Nevertheless, the relevance of the story for the preservation of endangered species cannot be so easily dismissed. Noah's example can be understood to establish a moral principle, not a uniquely religious one. Zygmunt Plater asserts that “we should adopt a Noah Presumption, a strong presumption in favor of protecting all endangered species, rather than a dismissive Noah's Choice, unless human necessities clearly outweigh the importance of doing so.”[FN222] Similarly, biologist David Ehrenfeld affixes the label the “Noah Principle” to the claim that “[l]ong-standing existence in Nature is deemed to carry with it the unimpeachable right to continued existence.”[FN223] In particular, Noah provides “an excellent precedent” because “[n]ot a single species was excluded on the basis of low priority, and by all accounts not a single species was lost.”[FN224] All species, therefore, have a right to exist.

Mann and Plummer call the Noah Principle “unethical and impracticable.”[FN225] They explain:

It is unethical, because trying to save every species perfectly would force our society to destroy many or all of its other accomplishments, an act of self-immolation that the ecologically concerned cannot force on *1232 others, who may have different but equally worthy goals. And it is impracticable, because this perfect duty is impossible to fulfill, even if our society were willing to turn back three hundred years of its history.[FN226]

In one respect this argument is misplaced. Mann and Plummer see the ESA as the embodiment of the Noah Principle, but the implementation of the law reveals that the ESA countenances choices among species.[FN227] Mann and Plummer further oppose the Noah Principle because it prevents any constructive debate about conflicts between endangered species and other interests.[FN228] They worry that reliance on the principle makes it impossible for us to play Noah, but that is incorrect. Mann and Plummer's real objection is that the ESA's apparent acceptance of the Noah Principle does not allow us to play God.

The existence of a moral duty to preserve all species does not depend upon our ability to satisfy that duty. A moral obligation is not extinguished by a lack of resources.[FN229] Nor are conflicting moral obligations unusual. Faced with multiple demands on our limited time and resources, we are frequently required to choose among many worthy causes that we acknowledge a duty to support. Mann and Plummer characterize the Noah Principle as unethical because it precludes such choices. And they endorse the methods of resolving the ethical dilemmas posed by resource limitations articulated in Guido Calabresi and Philip Bobbitt's famous book, Tragic Choices.[FN230] *1233 Yet Calabresi and Bobbitt exempt certain kinds of duties--including religious duties--from their general approach to allocating valuable but scarce resources depending upon their costs.[FN231] Thus, the difficulty of preserving biodiversity does not eliminate the duty itself.

The claims that Noah's example requires us to protect endangered species survive the attacks against them. While we may not know exactly which animals Noah acted to save, we do know that God asked him to save all kinds, and that Noah did so. That effort is consistent with other scriptural teachings on the obligation of people to care for what God has created. Or, seen through a different lens, Noah's ark provides a compelling example capable of sustaining a moral duty that fits with scientific teaching about the operation of ecosystems and the significance of individual species. Either way, Noah's effort to preserve biodiversity supports a similar effort on our part today.

B. The Legal Duty Established by the Story of Noah

Even if we should try to imitate Noah, it is not self-evident that the duty suggested by Noah's example (or any other moral, ethical, or religious duty for protecting endangered species) must be translated into a legal duty. The books containing the story of Noah--the Bible in general and Genesis in particular-- include countless other commands and stories that have never been adopted in statutory law. None of the proponents of an ESA based on Noah has explained why this is one of the commands demanding legal recognition.

There are, moreover, countless ways to protect endangered species wholly apart from governmental action. The Nature Conservancy is famous for using private funds to purchase lands that serve as habitat for endangered species; the Noah Conservancy has been established by Christian environmentalists to accomplish the same purpose. Private landowners often manage their property in a manner best designed to protect rare wildlife or plants, notwithstanding their limited economic incentive to do so. The small percentage of endangered species that live on public land[FN232] and the limited ability of the government *1234 to enforce laws against harming endangered species[FN233] make the actions of such private landowners essential to the preservation of many species. Private environmental groups fund efforts to study and protect endangered species around the world. Under such circumstances, the creation of a legal duty to protect endangered species will not be sufficient to assure the survival of such species; some would go further and say that a legal duty is unnecessary, too.

Unfortunately, the pressures on endangered species indicate that private efforts will be inadequate. Private developers cannot be expected to forgo tremendous economic profits in order to preserve a field that is home to an endangered bird or butterfly. For their part, governmental agencies have not demonstrated any greater willingness to sacrifice their primary mission in order to protect an endangered species. The Tennessee Valley Authority was more interested in the presumed benefits of the Tellico Dam than the survival of the snail darter. More recently, the Army reluctantly searched for training grounds that did not threaten an endangered species.[FN234] The intentional killing or capture of rare wildlife and plants continues to present a serious threat to the survival of many species in the United States and around the world. The *1235 incentives to destroy endangered species-- directly or indirectly, intentionally or accidentally--are often too powerful to be stymied by a moral duty alone. Hence the call for laws to preserve endangered species.

Perhaps, however, the legal duty suggested by the story of Noah should simply inspire us to try to protect all species. Even if we cannot actually save every species, we may still want to try to do so because we think that is an important aspiration.[FN235] The environmental laws are full of aspirational provisions that we know that we cannot meet. The discharge of pollutants into the water did not end in 1985, no matter what the Clean Water Act says.[FN236] This argument, however, neglects the fact that the ESA is more than symbolic legislation. A person who cuts down a tree that looks attractive to a spotted owl risks being sent to a real jail, not a symbolic one. The ESA goes far beyond stating aspirational goals: criminal fines of $50,000 and civil penalties of $25,000 indicate that the law's command cannot be followed only when convenient.[FN237] The symbolic legislation explanation does not fit such provisions. And symbolic provisions alone cannot be expected to preserve endangered species. Noah was motivated by his desire to obey God, and many today seek to protect the values of biodiversity that they find important, but a legally enforceable economic incentive or civil sanction will be more persuasive to those who do not share such values.

*1236 To say that the story of Noah provides the basis for imposing a legal duty to protect every species is not to say that the ESA itself has attained scriptural status. Even if the biblical account supports endangered species legislation, it does not mandate the precise terms of the ESA. Thus numerous writers have questioned whether the analogy between the ESA and Noah's example is appropriate. One ESA critic has noted that “Noah did not seize anyone's property to build the ark, nor did he tax anyone to finance the operation.”[FN238] Representative Lamar Smith has asserted that “Noah could have been condemned as an animal hater, fined and kept from launching his ark” under the ESA.[FN239] Senator Kempthorne doubts that Noah could have gotten the necessary ESA permits before the flood wiped out the earth.[FN240]

*1237 The consistency of the requirements of the ESA with the broader scriptural teachings has divided the religious community. Consider some of the conflicts described above. Should we protect butterflies or people from mosquitoes? A beetle or a highway to a hospital? The piping plover or a beach for off-road vehicles? Some find a scriptural preference for the human needs in all such circumstances. An article published by Focus on the Family-- a prominent evangelical organization--seized upon a conflict between southern California farmers and the endangered kangaroo rat to assert that “[t]here couldn't be a clearer sign of upside-down morals than a law favoring rats over humans.”[FN241] A Baptist leader has dismissed the ESA as “an unmitigated disaster.”[FN242] Such criticisms object to the sacrifices that the ESA demands that people make for the sake of biodiversity. Defenders of the ESA respond that Noah did not complain about the tremendous amount of time and money that he was asked to spend to preserve species.[FN243]

The resolution of this dispute depends upon contested understandings of the value of human life, the value of non-human *1238 life, and the cost of protecting each. Note that while the biblical account indicates an unmistakable preference for human life, the story of Noah demonstrates a high value for the preservation of every species, too. And the costs involved--the cost of the actual steps necessary to protect a species, the loss of available resources for other purposes, and the cost of not protecting a species--are rarely clear. Such conflicts between the needs of endangered species and the needs of humans have caused much of the current controversy over the ESA. But whatever the appropriate balance between people and endangered species that is prescribed by the story of Noah, that balance does not affect the suggestion that Noah's example requires that we treat all species of wildlife equally, or that the law require that we do so.

C. The Constitutionality of Legislation Based upon the Story of Noah

The creation of a legal duty to protect--or at least not to harm--rare wildlife and plants based on the story of Noah faces criticism from those who object to basing a law on a biblical imperative. Idaho Representative Helen Chenoweth has been particularly outspoken against the invocation of Noah as a justification for the ESA, protesting the incorporation of personal beliefs into laws that punish those who do not share those beliefs.[FN244] Secretary Babbitt has been criticized for implying that opposition to the ESA equals opposition to God.[FN245] *1239 Additionally, many critics of the ESA characterize much of contemporary environmentalism itself as a form of religious belief.[FN246]

These complaints are often cast in constitutional terms. Critics of Secretary Babbitt's vision of the ESA contend that his efforts violate the Establishment Clause.[FN247] Indeed, the Establishment Clause has been interpreted to preclude statutes enacted for a religious purpose and without any secular justification.[FN248] Laws based on the book of Genesis have been especially susceptible to Establishment Clause objections.[FN249] Other cases, however, indicate that the religious motivation of those supporting a statute does not render it unconstitutional provided that there is a plausible secular purpose for the law.[FN250] *1240 Moreover, the decisions finding Establishment Clause violations emphasized the absence of any secular justification for the statute,[FN251] and the statutes at issue addressed topics that impressed the Court as inherently religious--school prayer, the Ten Commandments, and creation versus evolution. Thus, some scholars have advanced Establishment Clause theories that would call into question a broader group of statutes motivated by religious beliefs. Abner Greene, for example, reads the Establishment Clause to bar legislation actually enacted for the dominant express purpose of advancing values commanded by religion, whether or not a secular defense can be made for the law.[FN252] Greene even posits a case in which a law protecting endangered species would be unconstitutional.[FN253]

*1241 Reliance upon the story of Noah does not appear vulnerable to an Establishment Clause challenge under any of these approaches. Initially, most of those citing Noah are trying to prevent the ESA from being changed, and there is no precedent for finding an Establishment Clause violation in a refusal to enact a law. It is conceivable, though, that Noah could be expropriated for affirmative ends--to support legislation providing greater funding for the ESA, or to amend the ESA to give greater protection to endangered species. The Establishment Clause issue raised in such instances would depend upon the role that the story of Noah played in the legislative process, though I conclude that any imaginable endangered species law based on Noah's example would be constitutional.

Consider four possible scenarios: (1) some members of Congress cited the story of Noah as the justification for the law, but most members of Congress voted for the law because of the other utilitarian and moral arguments for preserving biodiversity; (2) the law was actually motivated by the story of Noah, but it was publicly defended by utilitarian arguments for the preservation of biodiversity; (3) the law was expressly based on a predominantly moral use of the story of Noah; and (4) the law was expressly based on a predominantly religious use of the story of Noah. The law resulting from the first scenario survives under any theory of the Establishment Clause. Such a law is not based on a religious purpose, let alone a dominant one, because the majority of those voting for it did so for reasons wholly unrelated to religious beliefs. This scenario best describes the current use of the story of Noah. While Secretary Babbitt and others cite the story of Noah as a reason for protecting endangered species, other defenders of the ESA rely upon a host of utilitarian and moral arguments to reach the same conclusion. To date, the secular environmentalists defending the ESA have far outnumbered those supporting endangered species legislation because of Noah's example or other religious obligations. Nor does any proposed legislation to expand protections for endangered species cite adherence to the story of Noah as a purpose of the law.

*1242 Likewise, the law resulting from the second scenario would satisfy the Establishment Clause according to both the Supreme Court and Professor Greene. The existence of a secular justification for a law is sufficient under current Establishment Clause doctrine, regardless of the religious motivations of the supporters of the law.[FN254] Greene's objection to the use of religious beliefs to support a law explicitly encourages legislators to transform their religious beliefs into secular arguments.[FN255] Many of the religious groups defending endangered species legislation have offered the same kinds of utilitarian arguments as secular environmentalists, indicating that the use of the story of Noah would withstand an Establishment Clause challenge even if the imitators of Noah constituted a majority of the Congress.[FN256]

Nor does the third scenario present a violation of the Establishment Clause. The First Amendment prohibits the establishment of religion, not morality. The Court has never held that a law based on nonreligious moral arguments violates the Establishment Clause.[FN257] Moreover, the story of Noah can be read to provide a moral argument instead of an argument based upon a religious command. Secretary Babbitt and religious leaders invoking the example of Noah have emphasized that the story appeals to people of all (or no) religious faiths.[FN258] Thus, an endangered *1243 species statute could survive even if most members of Congress acted in reliance upon the story of Noah.

The law described in the fourth scenario would probably survive, too, though it presents the hardest case. Cases like Edwards v. Aguillard[FN259] and scholarly theories like Professor Greene's would strike down a law enacted for a dominant religious purpose as a violation of the Establishment Clause. The Court and Greene part ways, though, on the significance of a law's alternative, secular purposes. The presence of secular purposes alongside religious ones is irrelevant to Greene if the religious purposes predominate;[FN260] the presence of secular purposes normally saves a law under the Court's test.[FN261]

There are, of course, many nonreligious reasons for protecting endangered species. While there may not be an obvious utilitarian reason for protecting a particular endangered species,[FN262] there will always be a nonreligious moral reason for protecting an endangered species. Moreover, while one can imagine members of a legislature voting for an endangered species statute because of religious motivation, the purpose of an endangered species statute is not inherently religious. Such a statute, therefore, is different from the statutes found unconstitutional because the very aim of those statutes struck the Court as limited to religious ends.[FN263] Accordingly, while Greene may invalidate a law like that described in the fourth scenario, the Court would probably uphold it, and the law would not *1244 raise an issue at all for those judges and scholars who contend that the religious purpose of a statute is irrelevant under the Establishment Clause.[FN264] In short, the only plausible Establishment Clause objection to the story of Noah presupposes that a majority of Congress feels a religious obligation to support endangered species legislation and that the Court will strike down an environmental statute regardless of the absence of any religious effects. That seems pretty unlikely.

But the Establishment Clause does not exhaust the potential constitutional obstacles to reliance upon the story of Noah. The free exercise clause may override the ESA for individuals whose religious beliefs demand the taking of a particular endangered species.[FN265] A different sort of constitutional argument confronts the story of Noah if it is viewed as creating a moral obligation instead of a religious one. Other laws based on contested moral arguments have not fared well recently.[FN266] Remember, too, that the government possesses limited ability *1245 to determine which living organisms are worthy of legal protection.[FN267]

Several legal scholars have labored to distinguish laws protecting endangered species from other laws based on moral arguments, especially laws concerning abortion or homosexuality. Ronald Dworkin has argued that endangered species legislation can be distinguished from abortion legislation.[FN268] He agrees that the case for protecting endangered species must rest on moral arguments instead of utilitarian arguments--indeed, he accepts the government's ability to legislate to protect intrinsic values.[FN269] Abortion is different, Dworkin contends, for two reasons. First, the effect of governmental coercion on women who desire an abortion is far greater than the effect of governmental coercion on those affected by the ESA.[FN270] Second, our beliefs about human life are far more fundamental to our own selves than our beliefs about endangered species.[FN271] The first point depends upon the second. The reason why the experience of carrying a child to term is unlike any other activity *1246 that a woman will ever encounter is because of the unique value that most of our society places on human life. We view the pregnant woman's experience in a different light than a pregnant animal's experience precisely because we care more about people than animals. But this superior position of human life compared to other life is what some moral theories for protecting endangered species protest.[FN272] If all forms of life are equally valuable, then why should human experience matter more than the experience of animals? Dworkin's argument presupposes the very moral distinction that some environmentalists find so distasteful.

Once the primacy of human life is accepted, Dworkin is right that the coercion involved in abortion legislation is greater than the coercion in endangered species legislation. But the interest at stake is also greater. The high value on human life that causes Dworkin to treat the abortion decision as unique is also the reason why many want to protect the growing human life. Nor can it be said that the coercion worked by the ESA is trivial. The ESA can dictate where and how one lives, works, and worships. Although not at all the same as bearing a child, it requires a persuasive governmental justification nonetheless.

Similarly, Kent Greenawalt has acknowledged the potential tension between laws regulating endangered species and laws regulating homosexuality. On the one hand, he argues that “prohibiting wrongs per se is barred by premises of liberal democracy,” and therefore, laws restricting homosexuality (or other consensual sexual acts) are impermissible.[FN273] On the other hand, Greenawalt insists that “protecting the environment for its own sake is consistent with the premises of liberal democracy.”[FN274] If forced to choose between the positions, Greenawalt would side with his first assertion against laws prohibiting wrongs per se,[FN275] but that would doom any effort to rest *1247 the ESA on moral arguments once the utilitarian arguments are exhausted.

This debate travels into theories of liberal democracy, constitutionalism, and ultimate views of the good that transcend the arguments about specifically religious arguments. My sole point here is to identify the parallels between moral arguments for endangered species legislation and similar moral arguments for a variety of other laws.[FN276] I would sustain the constitutionality of endangered species legislation based on the story of Noah for the same reasons why the Court's precedents questioning reliance on moral arguments strike me as problematic. But if I am wrong about those precedents, then endangered species laws are jeopardized as well.

Admittedly, preserving biodiversity appeals to a different constituency than the laws whose moral justifications were inadequate to save them from constitutional attack. Also, few decisions have engendered more passionate debate than Roe v. Wade and Romer v. Evans. To extend such rulings to a law designed for such a popular cause as wildlife preservation is highly unlikely, whether or not the analogy is appropriate.[FN277] The presence of utilitarian justifications for preserving biodiversity as a whole further diminishes the likelihood that the absence of such justifications for some species and the reliance on the story of Noah (or other religious or moral arguments) will serve to invalidate the statute. That said, the constitutional ramifications of moral and religious arguments for environmental statutes deserve more attention, but I would not expect such arguments to carry the day.

V. PLAYING GOD

So the dilemma remains. We cannot protect every species, we do not protect every species, but the story of Noah (like any of a number of other moral or religious arguments) says that we have to. Suppose, however, that Noah was forced to choose between species. What would he have done? Or perhaps more *1248 importantly, how should those who seek to imitate Noah today decide which species should live and which should disappear forever?

The answer must remain uncertain, simply because Noah did not give us an example of how to choose among endangered species. That omission itself should give us pause. The resource constraints that appear so daunting to us pale in comparison to the task confronted by Noah. Perhaps, then, fidelity to Noah's example requires us to work to save all species trusting that God will enable us, like Noah, to accomplish a seemingly impossible feat. But that approach does not help the FWS, the Nature Conservancy or other groups that must decide how to allocate a fixed budget among many endangered species. Nor does that approach account for the human needs that cry out for additional money and attention--and that sometimes conflict with the needs of endangered species.[FN278] Noah was responsible for eight people, not six billion.[FN279] For these reasons, even those defenders of the ESA who consider the scriptures authoritative recognize the need to balance biodiversity and other concerns.[FN280] Indeed, some Christian writers have attempted to develop priorities for species preservation in a world where not all species can be saved.[FN281] Thus, while choices may be necessary, any decision to choose among species should be reached with great reluctance, recognizing that the *1249 failure to preserve a species is also a failure to imitate Noah, whose own efforts were rewarded by God.[FN282]

A. The Lessons of Noah for How to Choose Among Species

My guess is that Noah would have tried to save as many different kinds of species as possible. Noah protected all species, regardless of their size or appearance or apparent value, because that is what God told him to do. Imitating Noah would seem to require us to come as close to that result as we can. Moreover, to the extent that we are unable to protect every species, Noah's example suggests that the diversity of species has value in itself.[FN283] Genesis teaches that God created many, many different species, and when Noah heeded God's command to save them all, the importance of the diversity of life was reemphasized.

That goal suggests certain priorities for choosing among endangered species. First, the more species the better. Efforts to save an endangered species that will also benefit other endangered species would rank highest. Saving multiple species at one time is easily accomplished by focusing on the habitats of many different species live, instead of the individual species themselves. Many writers recommend that efforts to protect multiple species by protecting broader ecosystems merit high priority.[FN284] The current FWS priority scheme, by contrast, does *1250 not expressly prefer species whose preservation will also save other species.[FN285] The agency has demonstrated a de facto preference for HCPs that protect the most species,[FN286] but that policy has not been codified in the FWS's regulations or in the ESA itself. The agency recently proposed giving higher priority to proposed listings covering multiple species--essentially creating a preference for a species whose listing happened to be proposed in the same rulemaking as other species--but that rule is not yet in effect.[FN287]

The desire to save as many species as possible also supports consideration of more controversial factors such as the cost of preservation and the likelihood of success. Consider three ecosystems that contain 300 endangered species evenly distributed so that 100 species live in each ecosystem. If it would cost $50 million to preserve ecosystem A, $25 million to preserve ecosystem B, and $25 million to preserve ecosystem C--and if only $50 million is available for species preservation--then the preferable course would be to save ecosystems B and C and the 200 species that they contain. Similarly, if two songbirds are endangered but one is far more likely to recover, then the preservation of the songbird that is likely to recover should take priority. Some writers have endorsed the consideration of the cost and likelihood of success of recovery efforts in establishing priorities among species--like the triage system employed by wartime hospitals.[FN288] Such cost/benefit projections *1251 fit with the goal of saving as many species as possible, but the calculations make me squeamish in this context, and they certainly find no precedent in Noah. Nor does the FWS adhere to such an approach. The agency does give some priority to species that are most likely to recover, but that priority cannot override the mandate to try to prevent any species from going extinct, however unlikely it is to recover.[FN289]

Note that the emphasis here is on saving as many species as possible, not on saving ecosystems themselves. Of course, saving an entire ecosystem may well save a significant number of endangered species, but the two goals could diverge. A whole ecosystem may lack any endangered species; a small fragment of an ecosystem could contain many endangered species. In such instances it makes a difference whether ecosystem protection is the means to the end of saving endangered species, or vice versa. A number of writers would give priority to saving species in order to achieve their real goal of saving ecosystems.[FN290] Such concern for the larger environment finds support *1252 in much scriptural teaching. Genesis records that God described all of creation as good, not just particular animals and plants.[FN291] In contrast, the story of Noah omits any such ecosystem focus. In fact, Noah saved every species even as all of the earth's existing ecosystems disappeared around him. Imitating Noah, then, means putting species before ecosystems in the unlikely event such a choice becomes necessary. This is one instance, though, where following Noah's example may not necessarily lead to the same actions as fidelity to the balance of the biblical record.

Priority number two emphasizes diversity among species. Such diversity can be achieved by favoring preservation efforts that benefit species in different biological classifications. As Donald Regan has written:

[O]ther things being equal, a species is made more valuable by belonging to a sparsely populated genus or family or order. Taxonomically isolated species are likely to represent unusual modes of adaptation. Their existence increases the diversity of nature. That means both that there is more to know about what exists, and that a complete knowledge of what exists entails a greater knowledge of nature's possibilities.[FN292] *1253 The FWS agrees that genetically distinct species should be favored.[FN293] Likewise, the Forest Service must manage national forests to provide for “diversity of plant and animal communities.”[FN294] So while a Senate committee once commented that “[b]iologically, it makes sense to treat all taxonomic groups equally, or even to place some special emphasis on protecting plants and invertebrates since they form the bases of ecosystems and food chains upon which all other life depends,”[FN295] the FWS has emphasized that genetically unique species possess special value independent of their impact on an ecosystem.[FN296] Nonetheless, the FWS gives biological diversity “the lower order of priority setting” and expects to turn to this criteria to choose among species only rarely.[FN297]

In practice, the preference for diversity means that if the FWS has a fixed budget to spend on implementing the recovery plans for all endangered species, it should concentrate that money on the whooping crane or the manatee instead of the snail darter (which is one of 150 different species of darters)[FN298] or the northern spotted owl (which is one of three subspecies of the spotted owl species).[FN299] Or suppose that an environmental agency has $2 million dollars to spend on endangered species, and that it would $1 million dollars each to save the Indochinese tiger, the Siamese tiger, and the panda, each of which are highly endangered. While one hopes that it would never come *1254 to this, the diversity criteria says that priority should go to the pandas and one of the tigers, rather than saving both of the tigers and not the panda.

The third and weakest priority should attach to those species that provide the greatest utilitarian benefits to us. Noah declined to follow this course, though his preference for clean species instead of unclean species offers slight support for consideration of utilitarian values. The more controversial passages in Genesis that encourage people to use creation to satisfy their own needs provide somewhat greater support for a utilitarian priority.[FN300] Most of the writers who have considered choices among species find utilitarian concerns unnecessary (because people will act to protect species that are valuable to them even when there is no legal obligation to do so)[FN301] or misguided (because they disregard the independent value of a species).[FN302] While the claim that it is unnecessary to consider utilitarian concerns is often true, it fails to account for species that provide indirect benefits such as water purification and climate control that are not captured by the economic marketplace.[FN303] The claim that it is misguided to consider utilitarian concerns in establishing priorities is disingenuous for anyone who relies on the utilitarian arguments for the preservation of endangered species. That claim is legitimate, though, for those who espouse moral or religious justifications for preserving species that attribute independent value to biodiversity. Whether any weight should be attached to utilitarian benefits when establishing priorities among endangered species depends upon the comparative moral position of people and animals. Noah's example suggests that the utilitarian benefits of a species should be given priority only once the numerical and *1255 diversity priorities have been satisfied, and those benefits should be considered with the awareness that the same scriptures that provide some support for considering utilitarian concerns also emphasize that God considers all creatures to be valuable regardless of their usefulness to us.[FN304]

B. Alternate Proposals on How to Choose Among Species

That leaves several other ways that writers have proposed for choosing among species. One possibility is to favor the species that are the most endangered.[FN305] The FWS proceeds on such a “worst-first basis” when listing species.[FN306] The degree of endangerment certainly highlights the need to decide quickly whether or not to try to save a species. The triage model, however, suggests that some species may be so endangered that it is not worth investing precious resources to try to save them instead of another species that is more likely to recover. More importantly, unless we believe that we can save every species, a priority for the most endangered species will simply result in the extinction of other, not quite as endangered species. The resources used to preserve the most endangered species will be unavailable to preserve the next most endangered species. In other words, focusing on the most endangered species makes sense only if we are able to save each species as it rises to the status of most endangered. If that is impossible, and if choosing among species become necessary, then giving priority to the species that are most endangered presupposes that such species are the most valuable. There is no reason to believe that the *1256 species that happens to be the most endangered is by definition the most valuable. Again, a triage system would consider both the degree of endangerment and the likelihood of recovery, with the goal of saving as many species as possible.[FN307] Considering the degree of endangerment but not the likelihood of recovery will result in a lesser number and relatively random group of species that are saved.

Another possibility is to favor species that are the most advanced and complex in their development.[FN308] Such an approach is consistent with from a variety of moral theories, but it lacks support from the story of Noah. Nor do the other teachings of Genesis point in this direction. Christian writer James Nash has defended a priority system that favors the most advanced species as consistent with the biblical placement of people in a higher position than the rest of creation.[FN309] But even for those who agree that people occupy the highest position on the earth, it does not follow that all other species can be ranked along a continuum, with primates far closer to people than ambersnails. The voice of the scriptures on the unique status of people is matched by the silence of the scriptures on the relative value of all other species.

Or priority could simply be given to species that are most popular. This criteria probably best describes the actual practice of species preservation efforts today.[FN310] Indeed, Mann and Plummer have argued that “[i]f society prefers charismatic megafauna, priority should be given to them without apology.”[FN311] But the idea that popularity equals priority seems out- *1257 of-step with any theory of the value of species. Children's books portray the ark full of giraffes and hippos and lions, with beetles and slugs and kangaroo rats nowhere to be seen, but I can find no other indication that Noah would have conducted a public opinion poll to determine which species to save.

There are, however, two ways in which the popularity of a species could become relevant. First, popularity may serve as a proxy for a utilitarian value, especially aesthetic value. Large, charismatic, colorful species are especially likely to capture the public's eye. Or a species may be popular for cultural, not aesthetic reasons. The bald eagle and the jumping frog immortalized by Mark Twain are examples of species whose popularity results from the special place they occupy in the public memory.[FN312] To the extent that utilitarian values such as aesthetics or cultural importance deserve any priority, the popularity of a species may signal aesthetic worth. Second, efforts to protect popular species may promote support for efforts to protect less visible species.[FN313] The appeal of, and resources devoted to, the preservation of endangered species as a whole may depend upon the public's perception of whether a grizzly bear or a snail darter is likely to benefit. Alas, it remains equally possible that the protection of such popular species will exhaust the public's willingness to preserve biodiversity.

Noah, therefore, may have favored the preservation of the most species of the most different kinds--with their value to him considered almost as an afterthought--if he was forced to bring a limited number of species on board. Or he may have made his choices in a different manner; we cannot know with certainty today. But the very process of choosing among species *1258 should provide yet another argument for avoiding such choices in the first place. When we decide that we are willing to allow a species of tiger to become extinct in order to save the panda, or to preside over the demise of a species of whale so that we can save the manatee, we are in uncomfortable and uncharted territory. We are no longer playing Noah; we are playing God.

Perhaps the only thing worse than openly determining priorities among endangered species is to apply unstated priorities to the same effect. We already choose among endangered species, but we do not like to admit it. Those like Mann and Plummer who call for an explicit statement of priorities are often motivated by the reality that species are becoming extinct despite our efforts.[FN314] The existing, de facto priorities favor the species that are most popular with the public, even though more species and a broader range of species might be saved under a more direct and focused scheme of priorities. A formal list of priorities would also achieve the honesty that Calabresi and Bobbitt find so important when faced with an excruciating choice like that described here.[FN315] “Averting the eyes enables us to save some lives even when we will not save *1259 all,”[FN316] but we could save more lives if we fully analyzed what we are doing. Noah did not blind himself to the task at hand, either.

CONCLUSION

The Supreme Court's decision in Tennessee Valley Authority v. Hill,[FN317] holding that the ESA required the government to protect the snail darter instead of completing the Tellico Dam, often serves as a lightning rod for attitudes about endangered species. Noah's Choice uses the case for that purpose when it describes an exchange at oral argument in the Supreme Court:

“I have in my hand a darter, [Attorney General Griffin Bell] proclaimed, “a snail darter. . . . Bell handed the fish to the bench. The test tube made its way along the line of nine justices, each of whom solemnly peered at its contents before passing it to a neighbor. . . . The attorney general stood back, satisfied, as laughter filled the court. The laughter was halted by the quiet voice of Justice John Paul Stevens. “Mr. Attorney General,” he said, “your exhibit makes me wonder. Does the Government take the position that some endangered species are entitled to more protection than others?” Bell's smile disappeared.[FN318] Then Bell answered “no.”[FN319]

That is the answer demanded by the language of the ESA, current scientific consensus, and the many advocates of the existing law. Yet the recent debate over the ESA has questioned that orthodoxy. If we cannot protect every species, and if we do not protect every species, then perhaps we need not try to protect every species. That argument may make sense from a utilitarian perspective, but it fails to account for the religious, moral and ethical arguments for protecting every species. The biblical story of Noah offers one such theory; undoubtedly other religious, moral, and ethical traditions support similar *1260 theories. We do not know precisely how Noah accomplished his task, but Genesis does tell us that Noah saved all of the animals. If one wants to imitate Noah--either because of a sense of religious obligation or because of a moral duty like the Noah Principle--then we should try to save every species, too. Noah offers less guidance about how to choose among species if preserving them all proves to be impossible, but we can tease some clues from his story that can help us allocate our limited resources. The means that we should use to try to protect endangered species present exceedingly difficult questions in a society with limited resources and seemingly unlimited needs, but the original goal of the ESA--to protect every species--remains sound. We should keep trying to play Noah after all.

[FN3] See, e.g., 141 Cong. Rec. E304 (daily ed. Feb. 8, 1995) (statement of Rep. Kolbe) (asserting that the Fish & Wildlife Service has “the power to play God” through its interpretation of the ESA, quoting Hugh Holub, Feds Should Let States Handle Environmental Issues, Tucson Citizen, Jan. 30, 1995); Amending the Endangered Species Act of 1973: Hearings on S. 2899 Before the Subcomm. on Resource Protection of the Senate Comm. on Env't and Pub. Works, 95th Cong. 39 (1978) (statement of Sen. Culver) (“Who plays God the second time around?”); John Lowe Weston, Comment, The Endangered Species Committee and the Northern Spotted Owl: Did the “God Squad” Play God?, 7 Admin L.J. Am. U. 779 (1994).

[FN4] Despite the statute's command that the group is “to be known as the Endangered Species Committee,” 16 U.S.C. § 1536(e)(1) (1994), everyone calls it the God Squad. See, e.g., Portland Audubon Soc'y v. Endangered Species Comm., 984 F.2d 1534, 1537 (9th Cir. 1993); Endangered Species Act-- Bakersfield, California: Hearing Before the Task Force on Endangered Species of the Comm. on Resources House of Representatives, 104th Cong. 41 (1995) [[[hereinafter Bakersfield ESA Hearing] (statement of Leslie V. Reid, Pine Mountain Club, California); 141 Cong. Rec. S6342 (daily ed. May 9, 1995) (statement of Sen. Johnston); Jared des Rosiers, Note, The Exemption Process Under the Endangered Species Act: How the “God Squad” Works and Why, 66 Notre Dame L. Rev. 825 (1991).

[FN6] For a general overview of the ESA's requirements, see Michael J. Bean, The Evolution of National Wildlife Law 329-83 (1983).

[FN7] The task force held hearings in Belle Chasse, Louisiana; Boerne, Texas; New Bern, North Carolina; Bakersfield, Riverside, and Stockton, California; Vancouver, Washington; and finally in Washington, D.C. To say that the ESA was on the defensive during these hearings would be an understatement. See, e.g., Endangered Species Act: Washington, DC--Part I: Oversight Hearing Before the Task Force on Endangered Species Act of the Comm. on Resources, House of Representatives, 104th Cong. 46 (1995) [hereinafter Washington ESA Hearing Part I] (statement of Rep. Shadegg) (claiming that the ESA “is being used to violate property rights on a massive scale and to threaten our liberty. It is destroying jobs and causing enormous economic dislocation.”); Endangered Species Act--Vancouver, Washington: Hearing Before the Task Force on Endangered Species Act of the Comm. on Resources, House of Representatives, 104th Cong. 65 (1995) [hereinafter Vancouver ESA Hearing] (testimony of Lois Van Hoover) (claiming that “it is time to scrap the ESA and start anew”); Bakersfield ESA Hearing, supra note 4, at 2 (statement of Rep. Pombo) (“Many of my constituents are frustrated and angry about a law that allows government bureaucrats to put the protection of a rat, or fairy shrimp, or any other species, above the lives and safety of human beings.”). Some environmentalists, by contrast, viewed the hearings as a sham. See Endangered Species and Wetlands--Part I: Oversight Hearings Before the Task Force on Endangered Species and Task Force on Wetlands of the Comm. on Resources, House of Representatives, 104th Cong. 65-66 (1995) [hereinafter Louisiana & Texas ESA Hearings] (colloquy between Rep. Tauzin and Paul Davidson, president of the Louisiana Wildlife Federation); Paul Rauber, Eco-thug: Richard Pombo, Sierra, Jan.-Feb. 1996 at 16 (describing the hearings as “an anti-ESA road show” held in “out-of-the-way locales, soliciting anecdotal anti-ESA testimony while deliberately excluding expert and scientific opinion on its benefits”).

[FN8] See S. 1364, 104th Cong. (1995) (introduced by Sen. Kempthorne); H.R. 2444, 104th Cong. (1995) (introduced by Rep. Saxton); H.R. 2374, 104th Cong. (1995) (introduced by Rep. Gilchrest); H.R. 2364, 104th Cong. (1995) (introduced by Rep. Shadegg); H.R. 2275, 104th Cong. (1995) (introduced by Rep. Young of Alaska); S. 768, 104th Cong. (1995) (introduced by Sen. Gorton). The leading bills were extremely unpopular with environmentalists. See Endangered Species Act Amendments: Hearing on H.R. 2275 Before the Comm. on Resources, House of Representatives, 104th Cong. 4 (1995) [hereinafter H.R. 2275 Hearing] (statement of Rep. Studds) (characterizing H.R. 2275 as “an outright repeal of the Endangered Species Act”); id. at 9 (statement of Rep. Miller) (claiming that H.R. 2275 “is the repeal of the Endangered Species Act as people have come to know it”). For analysis of each of the bills, see J.B. Ruhl, Section 7(a)(1) of the “New” Endangered Species Act: Rediscovering and Redefining the Untapped Power of Federal Agencies' Duty to Conserve Species, 25 Envtl. L. 1107, 1153-59 (1995).

[FN9] See 143 Cong. Rec. H2282 (daily ed. May 7, 1997) (statement of Rep. Slaughter); id. at H2287 (statement of Rep. DeGette); id. at H2284 (statement of Rep. Boehlert); id. at H2300 (statement of Rep. Vento); id. at H2300-01 (statement of Rep. Miller). But see id. at H2290 (statement of Rep. Young) (“We did not repeal the Endangered Species Act, nor did we attempt to. We tried to rewrite it without any help from the minority at all, and this administration has been asked many times, and they sit on their fat never mind.”).

[FN10] The rhetorical force of the kangaroo rat illustration provoked a Fish & Wildlife Service memo instructing that government officials should “[a]lways call it a ‘kangaroo rat’, never a ‘K-rat’, or ‘rodent.”’ Endangered Species Act: Washington, DC--Part II: Oversight Hearing Before the Task Force on Endangered Species Act of the Comm. on Resources, House of Representatives, 104th Cong. 175 (1995) [hereinafter Washington ESA Hearing Part II] (quoting a 1987 memorandum regarding the anticipated listing of Stephens' kangaroo rat). The kangaroo rat controversy is discussed infra at note 241.

[FN24] Mann & Plummer, supra note 11, at 30-36. More specifically, “[a] species is a reproductive community of populations, reproductively isolated from  other populations, that occupies a specific niche in nature,” id. at 36 (quoting Ernst Mayr, The Growth of Biological Thought: Diversity, Evolution, and Inheritance 273 (1982) (emphasis omitted)), a definition that Mann and Plummer analyze at some length. See id. at 37-39; see also Holly Doremus, Listing Decisions Under the Endangered Species Act: Why Better Science Isn't Always Better Policy, 75 Wash. U. L. Q. 1029, 1088-1112 (1997); Kevin D.

Ritvo's wonderful book documents the way in which politics, military strategy, and other agendas influenced the classification of animals--and ultimately, people--in eighteenth and nineteenth century Britain.

[FN27] The ESA defines “species” to include “any subspecies of fish or wildlife or plants.” 16 U.S.C. § 1532(16) (1994). “Subspecies” is undefined in the  statute and imprecisely defined elsewhere. See, e.g., Edward O. Wilson, The Diversity of Life 406 (1992) (definition of a “subspecies” is “[s]ubdivision of a species. Usually defined narrowly as a geographical race: a population or series of populations occupying a discrete range and differing genetically from other geographical races of the same species.”). For competing views of the protection of subspecies, compare Washington ESA Hearing Part II, supra note 10, at 76 (statement of Glenn English, Vice Chairman, National endangered Species Act Reform Coalition) (criticizing the protection of subspecies), id. at 104 (statement of Dean Kleckner, President, The American Farm Bureau Federation) (same), and Vancouver ESA Hearing, supra note 7, at 39 (testimony of Barbara Tilly, Chairman, Chelan County Public Utility District Board of Commissioners) (same), with Washington ESA Hearing Part III, supra note 12, at 261-62 (statement of Bruce Babbitt, Secretary, U.S. Dept.

The 1982 amendments to the ESA authorized HCPs as a means by which a private party can incidentally “take” endangered species, otherwise prohibited by section 9, provided that the party has developed a sufficient plan to protect the species. See 16 U.S.C. § 1539(a)(2) (1994). Few HCPs were approved prior to the 1990's, see Bean, supra, at 7-10 (describing each HCP), but the Clinton Administration has made the development of HCPs a priority. See Oliver A.

[hereinafter FWS 1998 Proposed Priority Guidelines]. That guidance is similar to the existing priorities except that it raises the priority of delisting actions. See id. at 10,934 (explaining that “prompt delisting of recovered species and the reclassification of recovering species (from endangered to threatened status) is necessary to keep the public and other interested parties informed of a species' conservation status”).

[FN118] See FWS 1983 Priority Guidelines, supra note 90, at 43,103; accord FWS 1997 Priority Guidance, supra note 53, at 64,477 (“It has been long-standing Service policy that the order in which species should be processed for listing is based primarily on the immediacy and magnitude of the threats they face.”).

[FN119] See FWS 1983 Priority Guidelines, supra note 90, at 43,103.

[FN120] See id. at 43,103-05.

[FN121] See id. at 43,098 (“[T]he priority systems presented must be viewed as guides and should not be looked upon as inflexible frameworks for determining resource allocations.”); see also id. at 43,101 (rejecting the suggestion made by the Pacific Legal Foundation that the guidelines should be strictly followed by the FWS).

[FN122] The examples offered during the floor debate on the ESA in 1973 included whales, leopards, alligators, whooping cranes, wolves, falcons, cougars, the California condor, the bald eagle, and similar popular species. See, e.g., Senate Comm. on Environment and Public Works, A Legislative History of the Endangered Species Act of 1973, As Amended in 1976, 1977, 1978, 1979 and 1980, 97th Cong., 2d Sess., at 192, 371, 387, 403 (1982). For other assertions that the 1973 Congress was thinking of the most popular species, see 142 Cong. Rec. S6340 (daily ed. May 9, 1995) (statement of Sen. Gorton) (assuming that Congress intended the ESA to “protect our Nation's symbol of freedom, the bald eagle, and the other precious and unique creatures that we identified with as Americans”); Bakersfield ESA Hearing, supra note 4, at 61 (statement of Rep. Pombo) (complaining that “somehow we got from protecting bald eagles and grizzly bears to protecting fairy shrimp and beetles”); Louisiana & Texas ESA Hearings, supra note 7, at 136 (statement of Rep. Chenoweth) (noting that the original purpose for the ESA was “to save the great blue whale and the bald eagle”); (testimony of Wayne Wyatt, Manager, High Plains Underground Water Conservation District) (regretting that he originally supported the ESA thinking that “all we were trying to do was to protect the American Eagle, seals, maybe grizzly bears, some of the real species that were important”); Plater, supra note 80, at 850 (agreeing that “[t]he original images in the minds of members of Congress, as well as the public, probably were indeed... protection of ‘warm fuzzy’ creatures”); Snape, supra note 59, at 34 (noting that “many senators and representatives believed that the act was to be a legislative tool that primarily addressed charismatic megafauna like the bald eagle and American alligator”).

[FN123] See Drozdowski, supra note 112, at 572 (“In general, species that are viewed favorably in the public eye stand the best chance of survival under the present scheme.”); Lawrence H. Goulder & Donald Kennedy, Valuing Ecosystem Services: Philosophical Bases and Empirical Methods, in Nature's Services 23, 36 (Gretchen C. Daily ed., 1997) [hereinafter Daily] (“People seem to care more about eagles and panthers than about mosses and bacteria.”); Alan Randall, Human Preferences, Economics, and the Preservation of Species, in The Preservation of Species: The Value of Biological Diversity 79, 87-88 (Bryan G. Norton ed., 1986) [hereinafter Norton] (noting human preference for species providing utilitarian benefits and “those which have become the stuff of legends and patriotic symbolism, as well as those which are ‘pretty,’ ‘nice,’ or ‘cute and cuddly”’); Ike C. Sugg, Caught in the Act: Evaluating the Endangered Species Act, Its Effects on Man and Prospects for Reform, 24 Cumb. L. Rev. 1, 68 (1993) (“[H]ow would Americans respond to the question ‘Do we have to save them all?, when the vast majority of ‘them’ are insects and other creatures Americans regularly step on without so much as a second thought?” (citation omitted)). But see Roper Center of Connecticut, Public Opinion Online, survey conducted for Los Angeles Times, Nov. 1989, available in LEXIS, News Library, Arcnws File (poll indicating that of those willing to pay higher taxes in order to save endangered species, 64% would pay more taxes regardless of the species, while 31% would pay more taxes to protect certain species). Mann and Plummer assert that while most Americans would prefer bald eagles to a shopping center, “feelings are much less certain when it comes to canceling a $100 million golf course to save a bug nobody has heard of,” Mann and Plummer, supra note 40, at 48. But a poll asking a very similar question revealed that a butterfly would defeat a golf course by a 53% to 37% margin. See Roper Center of Connecticut, Public Opinion Online, Survey Conducted for Times Mirror Magazines, National Environmental Forum Survey, Mar. 10, 1992, available in LEXIS, News Library, Arcnws File.

[FN124] Plater, supra note 67, at 822; accord Plater, supra note 80, at 851 (describing “the paradigmatic images of the ESA” as “the large brown eyes of a baby seal or tiger or elephant, the fragile finery of an endangered crane, the brave splashing flukes and quavering underwater songs of humpback whales”); id. at 851 & n.25 (adding that “[t]he images deal with macrofauna, particularly with photogenic macrofauna,” and that “endangered plants seem to receive little intuitive allegiance from the contemporary human psyche, redwoods and saguaro cactus to the contrary notwithstanding, and endangered bugs and beetles receive even less attention or sympathy”).

Hill, 437 U.S. 153, 162 (1978) (citing the Interior Secretary's view that the snail darter would become extinct if the Tellico Dam was completed because the streams preferred by the fish would be flooded once the dam was closed); Endangered and Threatened Wildlife and Plants; Proposed Rule to List Three Aquatic Snails as Endangered, and Three Aquatic Snails as Threatened in the Mobile River Basin of Alabama, 62 Fed.

[FN189] See Genesis 7:2-3 (instructing Noah to take seven pairs of each clean animal and each bird, but only one pair of each unclean animal); see also Rolston, supra note 174, at 139 (making this observation). By contrast, God's initial instruction to Noah required two of every species, see Genesis 6:19-20, and the actual progression of animals onto the ark occurred “two by two,” see Genesis 7:9.

[FN190] See Genesis 8:20 (New Int'l) (“Then Noah built an altar to the LORD, and took of every clean animal and of every clean bird, and offered burnt offerings on the altar.”).

[FN191] See Genesis 9:3-4.

[FN192] The broader reading of the story of Noah is that it imposes an obligation to protect species “in numbers sufficient to preserve their fruitfulness.” Bouma-Prediger & Vroblesky, supra note 181, at 22. For an argument that Christianity imposes a duty to protect individual animals in addition to species as a whole, see Nash, supra note 181, at 179-81.

If we ignore them, we sink. If we focus on saving them, they will bring us home.”).

[FN195] See Genesis 1:26 (“Then God said...‘let [man] have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth.”’); Genesis 1:28 (commanding man to “fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth”); see also Jeremiah 27:6 (indicating that God gave the wild animals to serve Nebuchadnezzar, the king of Babylon); Psalms 8:6 (“You have made him to have dominion over the works of Your hands; You have put all things under his feet.”) (emphasis in original). The classic example of the argument that such passages are to blame for modern environmental problems is presented in Lynn White, Jr., The Historical Roots of our Environmental Crisis, 155 Science 1203 (1967); see also George Cameron Coggins, Snail Darters and Pork Barrels Revisited: Reflections on Endangered Species and Land Use in America, in Kohm, supra note 51, at 72 n.1 (“In Genesis, God commanded Man to assert dominion ‘over every thing that moves.’ This injunction has been observed much more closely than other biblical lessons.”).

[FN203] See, e.g., Leviticus 25:43 (instructing that “[y]ou shall not rule over [your slaves] with rigor, but you shall fear your God”); 1 Kings 4:24 (describing a king who had dominion and who “had peace on every side all around him”); see also Lloyd H. Steffen, In Defense of Dominion, 14 Envtl. Ethics 63, 64-66 (1992) (analyzing other scriptural uses of the word “dominion”).

[FN204] See Ezekiel 34:4 (New International) (prophet observing that “[t] hose who are sickly you have not strengthened, the diseased you have not healed, the broken you have not bound up, the scattered you have not brought back, nor have you sought for the lost; but with force and with severity you have dominated them” (emphasis added)); see also Nash, supra note 181, at 103 (asserting that the dominion mandate does not support “oppression” or “despotic, totalitarian rule over nature”).

[FN205] See New Geneva Study Bible, supra note 177, at 8 n.26 (describing the command to exercise dominion as a “cultural mandate to rule the creation as benevolent kings”); Nash, supra note 181, at 104 (listing the affirmative obligations of Old Testament rulers); Young, supra note 179, at 172 (detailing the obligations imposed on rulers by God throughout the Old Testament); William Dyrness, Stewardship of the Earth in the Old Testament, in Granberg-Michaelson, supra note 200, at 53 (contrasting the rule of Hebrew kings with those of the ancient Near East).

[FN206] God's provision for creation is illustrated throughout the scriptures. See, e.g., Psalms 36:6 (“O Lord, You preserve man and beast.”); Psalms 147:8-9 (New Int'l) (observing that God “supplies the earth with rain and makes grass grow on the hills”); Matthew 6:26, 28 (noting that God feeds the birds and clothes the grass). Likewise, the New Testament states that dominion belongs to Jesus Christ, see 1 Peter 4:11, and that Jesus taught that “[w]hoever wants to become great among you must be your servant, and whoever wants to be first must be your slave.” Matthew 20:26-27 (New Int'l); see also Jim Ball, Jesus Christ, Creation and the Protection of God's Creatures, Green Cross, Winter 1996, at 8-11 (describing Jesus's concern for the protection of wildlife). The servanthood model for dominion is discussed in Young, supra note 179, at 171; Susan Power Bratton, Six Billion & More: Human Population Regulation and Christian Ethics 106-07 (1992); Bruce J. Nicholls, Responding Biblically to Creation: A Creator-Centered Response to the Earth, 17 Evangelical Rev. of Theology 209, 218 (1993); see also Dietrich Bonhoeffer, Creation and Fall/Temptation 43 (1997) (“There is no dominion without serving God.”).

[FN207] See, e.g., Thomas Sieger Derr, Environmental Ethics and Christian Humanism 22 (1996) (characterizing stewardship as “the real, orthodox Christian attitude toward nature” which teaches that “[w]e are trustees for that which does not belong to us”); Francis A. Schaeffer, Pollution and the Death of Man: The Christian View of Ecology 70 (1970) (contending that “we are to exercise our dominion over these things not as though entitled to exploit them, but as things borrowed or held in trust”); Young, supra note 179, at 173-77 (noting that stewardship implies delegated authority akin to a trust, contradicts human autonomy, implies moral responsibility, requires proper use and management, and involves human creativity). For criticisms of the stewardship model as human centered or hierarchial, see Michael S. Northcott, The Environment and Christian Ethics 129-30 (1996); Clare Palmer, Stewardship: A Case Study in Environmental Ethics, in The Earth Beneath: A Critical Guide to Green Theology 67-86 (Ian Ball et al. eds., 1992); see also Bill McKibben, The Comforting Whirlwind 51 (1994) (complaining that “the idea of ‘stewardship’ is so lacking in content as to give us very little guidance about how to behave in any given situation”). See generally Fowler, supra note 193, at 76-90 (1995) (surveying a range of Protestant views of stewardship).

[FN208] See Genesis 1:20-25. The implications of the creation story for biodiversity preservation are discussed in Peter DeVos et al., Earthkeeping in the Nineties: Stewardship of Creation by the Fellows of the Calvin Center for Christian Scholarship, Calvin College 39-40, 237-54 (rev. ed. 1991); Barlow, supra note 176, at 797-812; Rolston, supra note 179, at 137, 140.

Opponents of the ESA use the metaphor, too. See 125 Cong. Rec. 23867 (1979) (statement of Sen.

[FN214] Genesis 2:15. The significance of the obligation to “keep” the earth is revealed by other uses of that word in the scriptures. See Genesis 3:24 (describing how God placed an angel at the eastern edge of Eden to “guard” the garden from people seeking the tree of life); Numbers 6:24 (benediction asking the Lord to bless you and to “keep” you); see also Van Dyke et al., supra note 181, at 90 (commenting that “Adam probably would not have looked at an ostrich as a large pair of drumsticks or a hippopotamus as a ton of chuck steak”); Ronald J. Sider, Redeeming the Environmentalists, Christianity Today, June 21, 1993, at 28 (“[O]ur dominion must be the gentle care of a loving gardener, not the callous exploitation of a self-centered lord.

But Ehrenfeld finds other values--non-economic, religious values--capable of championing all living species. See id. at 204-11.
W]hen a community or species has no known economic worth or other value to humanity, it is as dishonest and unwise to trump up weak resource values for it as it is unnecessary to abandon the effort to conserve it. Its non-humanistic value is enough to justify its protection--but not necessarily to assure its safety in this human-obsessed world culture.

[FN235] That is the Clinton Administration's position:

I think we should continue to have an Endangered Species Act which sets a goal of striving to protect from going extinct all species in the United States, at least strive to protect them from extinction at the hands of human causes. That doesn't mean that we ultimately can hope to achieve that goal. Whether we can achieve that goal depends on, among other things, the status of some of those species, the amount of money that is appropriated for the program, the extent to which we are creative in structuring partnerships... between government and private landowners and some of the tradeoffs that we make between species protection and socioeconomic factors.
H.R. 2275 Hearing, supra note 8, at 33 (testimony of George T. Frampton, Jr., Assistant Secretary, Fish & Wildlife & Parks, Department of the Interior). Mann and Plummer would not necessarily object to such a goal.

[FN253] See Greene, The Irreducible Constitution, supra note 252, at 305-06 (suggesting that an Endangered Species Act enacted by a state in which “[v] irtually all of the legislators are observant Christians, and virtually all of the legislative arguments for the Act invoke religious authority” would violate the Establishment Clause); see also Conkle, supra note 252, at 18 (contending that an endangered species law that “depends upon a religious belief that is inerrantly held” violates the Establishment Clause, while a similar law based upon a non-inerrant religious belief is constitutional).

[FN255] See Greene, The Political Balance of the Religion Clauses, supra note 252, at 1621 (finding no Establishment Clause problem “if the religious believers are willing to translate their religious source of value into secular terms, because then the nonbeliever perceives that she can participate in the debate”).

[FN260] See supra note 252.

[FN261] See supra note 251 (citing cases). Greene reads the Court's precedents as establishing a dominant express religious purpose test. See Greene, The Political Balance of the Religion Clauses, supra note 252, at 1624. To be sure, there is language in several of the Court's decisions suggesting that the religious purpose of a statute can be less than total and still violate the Establishment Clause. See Edwards, 482 U.S. at 590-93 (referring to the law's “preeminent” and “primary” religious purpose”); id. at 599 (Powell, J., concurring) (opining that “[t]he religious purpose must predominate”); Stone v. Graham, 449 U.S. 39, 41 (1980) (concluding that “[t] he pre-eminent purpose for posting the Ten Commandments on schoolroom walls is plainly religious in nature”). But in each case emphasizing the purpose of a statute, the Court determined that there was no secular purpose for the statute--the legislature's only purpose was religious. See supra note 248 (citing cases).

[FN262] See supra Part III.B (describing how the utilitarian arguments for protecting endangered species fail to provide a justification for protecting every endangered species).

Rev. 115, 144 (1992) (“Left undefined, the purpose prong is an invitation to mischief--a not-so-subtle suggestion that those whose understandings of justice are derived from religious sources are second-class citizens, forbidden to work for their principles in the public sphere,” but rejecting the complete abandonment of the purpose prong).

[FN265] The free exercise argument was raised unsuccessfully in United States v. Lundquist, 932 F. Supp. 1237 (D. Or. 1996) (Native American charged with possessing bald eagle feathers), and United States v. Billie, 667 F. Supp. 1485, 1497 (S.D. Fla. 1987) (Native American charged with possessing panther parts). The Religious Freedom Restoration Act (RFRA) could yield a different result. See United States v. Gonzales, 957 F. Supp. 1225 (D.N.M. 1997) (upholding a RFRA challenge to the criminal prosecution of a Native American who shot a bald eagle for use in a religious ceremony). But see United States v. Jim, 888 F. Supp. 1058 (D. Or. 1995) (rejecting a RFRA challenge to the conviction of a Native American who killed several bald eagles). RFRA no longer limits the actions of states, see City of Boerne v. Flores, 117 S. Ct. 2157, 2171-72 (1997), but the applicability of the statute to federal government actions may well remain intact, see In re Young, 1998 U.S. App. LEXIS 7348 (8th Cir.

[FN319] Well, sort of. Noah's Choice paraphrases Bell as answering that “[n] o...the government was not taking the position that some species are better than others.” Id. at 168. According to another source, however, Bell was never quite that direct. He first said he did not have to reach that point, and then tried to shift responsibility to the lower court's holding. Finally, when Justice Stevens asked whether the ESA “distinguish[es] as among various priorities in the different species,” Bell conceded, “[i]t does not. It looks to the list. Once it gets on the list, it is an endangered species.” See Donald S.
