Recently, I wandered through "Audubon's Aviary," an exhibit at the New York Historical Society featuring watercolors by John James Audubon of birds that have, since Audubon painted them in the first half of the nineteenth century, become endangered or extinct. It was the right place to think about loss and the natural world. But, although death was everywhere apparent in the show, it was not a lugubrious place: Cries of birds--whooping crane, crested caracara--were piped in, and video images of actual birds appeared on a screen. And, of course, there were Audubon's grand paintings, part of his vast enterprise to paint in life-size every bird in America. His paintings, and the exhibition, made me think of a line in Randall Jarrell's poem about the mockingbird:
He imitates the world he drove away
So well that for a minute, in the moonlight,
Which one's the mockingbird? Which one's the world?
Audubon was famous for animating his bird subjects--the terrified bobwhite quail scattering before the talons of a red-shouldered hawk look like panic- stricken pogrom victims and make you forget that, before being given such dramatic life, they were shot and posed by Audubon himself, who also had killed the killer hawk. Audubon killed in order to capture. A Bewick's wren, sitting innocently on the branch of an elm, was, according to Audubon, shot "standing ... in the position in which you now see it."
Death is everywhere in Audubon's work, but there are different kinds of death. His painting of a pair of Eskimo curlews has a strangely prophetic quality. In Audubon's painting, the female bird is dead--not shot or visibly maimed but simply dead--the only time Audubon painted a dead bird whose cause of death was not apparent. The dead bird lies stretched on the ground, her pale underparts exposed. The male bird looks sideways at its dead mate, with a kind of avian astonishment. There were huge flocks of Eskimo curlews in the 1870s, but, as the passenger pigeon diminished, it was turned to as a market bird, and, 20 years later, the bird was essentially gone. The last official sighting was in the 1960s; today, it is presumed extinct.
Does it matter? What claim should this bird, or any other missing creature, have on our conscience? Extinction is nothing new; there are more extinct species than extant ones. We ourselves stand on the bones of superseded primate ancestors. Extinction is hardly a phenomenon only of modern industrial civilization; it is widely believed that the woolly mammoth was hunted to extinction by Neolithic man, and I learned from a book about avian extinction called Hope is the Thing with Feathers that "prehistoric islanders in the Pacific killed off some 2,000 bird species, diminishing by one-fifth the global number through a variety of activities, including habitat destruction."
But there is something about the disappearance of animals in the modern age that is different. I would not presume to know the mental state of those prehistoric islanders, but I can't help but imagine they were not conscious of the end they were causing. Edward O. Wilson, the great biologist, has speculated that, having evolved in the midst of abundance whose limit we could never fathom, we are all but programmed to go at nature with an exterminating fury necessary for our own survival that, until quite recently--when modern technology amplified human will to an equally unfathomable degree--had few lasting consequences.
I associate that pre-modern delusion of abundance with my assimilating grandmother, who was born on the Lower East Side in 1900. Shedding Yiddish and Jewish ritual observance as a young woman, it never occurred to her that her language or people could disappear in traumatic fashion; there was plenty back in the old country and a sense of everrenewing abundance. Similarly, those first settlers who came here--like Audubon himself, who arrived in this country from France in 1803, the year the Louisiana Purchase doubled the size of the country--could hardly imagine that swinging an ax or firing a gun might, in the space of 50 or 100 years, lead to the end of entire species. Nowadays, though, we must prop up the natural world we evolved to contend with, which is, to say the least, stressful and confusing.
In September 1914, Martha, the last passenger pigeon--a bird that, in Audubon's day, was the most populous bird on earth--died at the Cincinnati Zoo. The last wild bird had been shot by a boy some years earlier in Ohio. Martha's death made national news, and, when she died, her body was frozen into a 300- pound block of ice by the Cincinnati Ice Company, stopping time when it was already too late. The bird was sent by train to Washington, D.C., to take up posthumous residence at the Smithsonian where it became a sort of stuffed celebrity, lent out from time to time for fund-raisers in Cincinnati or celebrations in San Diego.
Four years later, the last Carolina parakeet died in the same zoo. The news was more muted, and the bird itself far less well known. I imagine that, after the slaughter of World War I, the death of a bird, even an entire species, could hardly register in the same way on the national consciousness. Our own world, certainly, has its share of human horror and political distractions.
But our technology, which of course plays a role in extinction, also can play an opposite role, in the same way that the Florida Everglades are essentially maintained by pumps and sluices built by the Army Corps of Engineers that, 100 years ago, all but destroyed the Everglades. Recently, I published a tribute in the Los Angeles Times to the Carolina parakeet on the ninetieth anniversary of its extinction--only to receive an e-mail from a scientist at the San Diego Zoo, telling me about the po'ouli, a Hawaiian bird I had never heard of. The last po'ouli died at the Maui Bird Conservation Center at 11:45 p.m. on November 26, 2004. Needless to say, the disappearance of the bird was not national news. Audubon never painted the bird; it was only discovered 35 years ago.
After the bird's death, tissues were taken from the bird and grown out--not easy to do with bird cells--but scientists did manage to obtain fresh cells that had grown and divided and that contain the entire genetic code for the bird. Cryopreserved in the Frozen Zoo, these cells might someday be thawed and reconstituted. We may yet be able to imitate--and even replicate--the world we drove away far more than Audubon ever imagined. It is hard to conceive of the bird flapping out of extinction, but it is certainly a step beyond holding Martha the passenger pigeon by the feet upside-down in a tank of water. Likewise, breeding in zoos is going to be, and already has proven, the salvation of a number of species already gone from the wild.
Questions about extinction and conservation stir complex human questions that are difficult to answer but important to frame. What do we owe the natural world and why? Is it pure self-interest--the need to maintain biodiversity in order to maintain healthy balance in the world we draw food and medicine from? Or is there a deeper, transcendent sense of obligation, even in a post- Darwinian world? Are we still biblical stewards of the earth? And what would we sacrifice to save a bird, or an animal lower on the evolutionary ladder?
Just last month, The New York Times carried an article about an area of the Pine Barrens slated for development that would endanger short-eared owls living there, as well as the tiger salamander. I immediately felt the $1.5 billion resort development had no business jeopardizing short-eared owls, wonderful birds I am instantly drawn to. But I was embarrassed to discover I didn't really care about the tiger salamander in the same way. I dutifully read up on the amphibian and brought my sentiments into line with my political convictions.
Of course species are used as a rallying cry to save a whole habitat, but the question still remains: How do we know what to save, at what cost, and why? I often think of the two missionaries in A Passage to India explaining to the native population that God's house has many mansions and all are welcome in it, black and white. But the question of animals quickly arises--what about monkeys? "Old Mr. Grayford said No, but young Mr. Sorley, who was advanced, said Yes; he saw no reason why monkeys should not have their collateral share of bliss, and he had sympathetic discussions about them with his Hindu friends. " But the Hindus press the point to a degree that challenges even the advanced Mr. Sorley:
And the jackals? Jackals were indeed less to Mr. Sorley's mind but he admitted that the mercy of God, being infinite, may well embrace all mammals. And the wasps? He became uneasy during the descent to wasps, and was apt to change the conversation. And oranges, cactuses, crystals and mud? and the bacteria inside Mr. Sorley? No, no, this is going too far. We must exclude someone from our gathering, or we shall be left with nothing.
We are still in some sense having this exchange, though it is more urgent since it is not our Father's mansion but our own that we are debating admission into. And the answer will tell us something not of the quality of God's mercy, but of the quality of human civilization.
Jonathan Rosen is the editorial director of Nextbook. His fourth book, The Life of the Skies: Birding at the End of Nature, has recently been published.

If it is "our Father's mansion," then we should perhaps view our stewardship in terms of our Father's expectations. Which of the plagues of Egypt and the trials of Job should we preserve? Jackals? Bacteria? AIDS? The SARS virus? Polio? Smallpox? The mosquito which spreads malaria, not to mention that pathogen itself. The Endangered Species Act, read most strictly, would require affirmative efforts to preserve the Anopheles mosquito, if we were in a position to eradicate it. (Not via mosquito nets, any time soon.) A farmer in the U.S., about to plow his fields for another season, is prohibited from doing so at a depth to sow the crop he and his family have grown on this land. Because a mouse species, in danger through no fault of the farmer, lives under his fields. This is the U.S., and there is always some subsidy (not necessarily applicable to this particular farmer), and always an array of lawyers (dare I say "special interest"?) to force him to park his tractor and retire. What if this farmer is in rural Africa, or South America, or south-east Asia, and is about to plow his fields the old-fashioned way, using oxen (or his wife or sons and daughters) to pull the plow. And there is an endangered mouse species living under his fields. And his family, or his village, will go hungry if he cannot plow and plant and harvest. Do we have a different viewpoint? Should we? Many species came before us and disappeared before us. Many species have come and gone since "man" became significant in the environment. Some disappeared because of us, some not. Mr. Rosen laments the extinction in 2004 of a bird species discovered only 35 years ago. I regret it, as well. But should we turn our lives and activities upside down, at any cost, in the hope of preserving a species with an apparent life expectancy of 30 years? Within "our Father's house" each species has done what came naturally in order to preserve and promote itself, over millions of years. No bacterium or virus ever worried that it's host species might die out. No predator hesitated to consume its prey. No prey species wondered what would happen to its predator if the herd managed to go over that ridge and leave the killer behind. Must we preserve the insect species, or the microbes, until they have eliminated the mammals? Is not reasonable to try to eliminate pests? Rats in cities? Mice on farms? Is it unacceptable to own a cat on a farm, when someone has identified an endangered mouse species in the fields? Ticks which carry Lime disease? Anopheles mosquitoes? No other species, as far as we know, is even capable of weighing the effects of its actions. Why is it unacceptable for us to consider a cost/benefit analysis before deciding to sustain some species at the expense of continuing our farming or development or ... ? Why is an owl, or a mouse, or a salamander, or ... a priori more important than anything else? The way we make these decisions is a cheap political cop-out, with a very expensive price tag for the rest of us. Business as usual, of course.

"What claim should this bird, or any other missing creature, have on our conscience?" The question is: Why do humans believe they have a special claim to the natural world? If not for a prehensil thumb, we would be no more able to control nature than a kangaroo. The fact that humans believe they have a right to all the riches of the world because a deity invented by man told us that we "are the stewards of the earth" is preposterous and delusional. Yet, for all our mental capacity and ability to reason, we, as a global society, cannot seem to understand that unless we learn to control our own populations in the same way we "manage" wildlife populations, we will all eventually perish from starvation, disease, or warfare. Humans are ebola to the natural world.

Species extinction matters a lot more to the human psyche than it matters to the environment, "environment" read here as non-human nature.

Species extinction matters a lot more to the human psyche than it matters to the environment, "environment" read here as non-human nature. I would suggest whoever posted this read up on the cascading effect species extinction can have on an entire ecosystem. My impression from recent articles in SCIENCE and NATURE is that at least some extinctions can have effects far beyond the absence of the particular organism per se since some species, particularly predators, anchor an extensive web of species relationships. Just try growing flowers in the Texas Hill Country: the absence of wolves, etc., has led to such a destructive proliferation of deer that a year-round hunting season would not control the burgeoning populations. Regarding viruses, the poster might want to read about the metaphor of the "circle" instead of the "tree" of life, since it appears viruses may have had an important role in evolution by causing distantly-related microorganisms to involuntarily share their DNA around early on.

| Posted by aberz aberz chooses worst cases to argue (roughly) that if we do not want to save pathogenic bacteria, we are inconsistent in wanting to save endangered bird species. But it is reasonable to take human wishes into account – no one wants to save pathogenic bacteria, but many humans feel differently about the charismatic megafauna. What’s wrong about that? I’m allowed to have wishes and values, as much as anyone else. If enough people have the same values, they become part of the political discourse. If not, not. Politics exists to mediate human wishes. It’s interesting to look at aberz’s list of horrors. “Which …. should we preserve? Jackals?” Yes, of course. “Bacteria?” Our species would die off without our gut bacteria. Anyway, while I am not a lawyer, I doubt that one-celled organisms are covered under the Endangered Species Act. “AIDS? The SARS virus? Polio? Smallpox?” Well, these are all viruses, so most would not consider them as living. Smallpox is an interesting case. It seems very likely that the only smallpox virus in the world exists in two virology labs. When the disease of smallpox was eradicated in 1977, there was a spirited debate whether or not to destroy the final stocks, lest it somehow get loose in a now unvaccinated human race. The decision was to keep it, because you never know when you might want the information represented by its genome. That’s one of the utilitarian arguments for preserving biodiversity. I think in general that if there is little cost, most people would opt to save an endangered species. The argument centers on costs and benefits, which is reasonable, as long as human wishes are included in the calculations somehow.

Regarding aberz's comment, In the interest of establishing accurate background, here’s the paragraph of the Endangered Species Act that refers to insects: "(6) The term “endangered species” means any species which is in danger of extinction throughout all or a significant portion of its range other than a species of the Class Insecta determined by the Secretary to constitute a pest whose protection under the provisions of this Act would present an overwhelming and overriding risk to man." see: http://www.fws.gov/endangered/ESA/sec3.html Thus, the Anopheles mosquito would not be protected under the Act.
