Across the globe, millions of trees have been martyred to provide the paper upon which the sorry tale of man’s inhumanity to nature is recorded. Animal shows and channels dedicated to them have proliferated on air, telling us why each and every one of nature’s creatures is special, lovable and deserving of protection. However, sometimes I think it useful to question the rationale. Does nature accord each and every species a right to exist? Do we have an obligation to protect them all from the consequences of human activity?
The indisputable answer to the first question is a resounding no! No species on this earth, humans included, enjoys an absolute right to exist, at least not one that Mother Nature recognizes. According to Dr. Richard Leakey, former head of the Kenya Wildlife Service and world-renowned conservationist, since life first appeared, more than 99% of all species that ever existed have become extinct. From the dodo to the dinosaur, all who didn’t get with nature’s evolutionary programme brought upon themselves the indignity of having their graves dug up by archaeologists and their naked bones displayed to all and sundry.
Far from being rare, extinction is very much a fact of life. It is nature’s age-old mechanism for getting rid of the evolutionary chaff. From the very beginnings of life on this planet, extinction’s agents have come in many forms -meteorites, climate change, disease and other animals- none of which have been particularly welcome. However, special condemnation has been reserved for the latest incarnation, Homo Sapiens.
By most accounts, we are living in a period of mass extinctions. Writing in the American Scientist magazine, Dr. Donald A. Levin notes that the rate of extinction occurring in today's world is exceptional -as much as 100 to1,000 times greater than normal. Anywhere from 35 -150 species disappear every day. In 2008, the International Union for the Conservation of Nature and Natural Resources (IUCN), the world's main authority on the conservation status of species, "confirmed an extinction crisis, with almost one in four [mammals] at risk of disappearing forever". A 1998 survey by the American Museum of Natural History found that 70% of biologists view the present era as part of a mass extinction event, the fastest to have ever occurred.
While man undoubtedly bears some blame for this state of affairs, his contribution has been less than stellar. Leakey considers “our role in this extraordinary [extinction] saga has been minuscule and so far…not statistically significant”. And while some, such as E. O. Wilson of Harvard University, predict that man's destruction of the biosphere could cause the extinction of one-half of all species in the next 100 years, in the grand scheme of evolutionary things, this is not a lot. Other Extinction-Level Events (ELEs) such as the Permian-Triassic decimated up to 96% of all marine and 70% of land specie. Nonetheless, the “crisis” has many people worried.
The typical reaction has been to attempt to save everything. Extinction, though, is not necessarily a bad thing. It creates room for better adapted species to develop and survive and also affords us the opportunity to rid this planet of any that make our lives a living hell, such as mosquitoes, bedbugs, cockroaches and tse-tse flies. As Leakey rhetorically asked in his famous ‘bunny huggers” speech, “Given the inevitability of extinctions, and bearing in mind that most of these losses will come about as a consequence of activities beyond the control of individual nations or their conventions, should we really be concerned about the loss of a few species that results from international trade? Will the world be any worse off if there are no longer pangolins, brown hyenas or pandas? The Europeans don't seem to have suffered from the loss of the woolly rhinoceros and how many Americans even remember the giant sloth that slipped into extinction some ten thousand years ago? Will Africans miss the elephant or the rhino if these too disappear? Is the elephant any more important than an orchid that grows near tropical wetlands? What about the extinction of hundreds and thousands of species that we humans have not yet even discovered? Does it matter if they become extinct before we even know that they exist?”
Actually, to try to preserve everything would be a clear challenge to nature’s idiom of survival for the fittest. In humanity’s insatiable consumption and material progress, Mother Nature is once again wielding her broom and sweeping away species that have overstayed their welcome. Better, I think, to go with the flow and accept that some, even many, species will have to go. The evolutionary New World Order with mankind at the top of the food chain is unlikely to collapse any time soon. This means that species that cannot adapt to our destructive ways will either have to hide and wait until we are spent or they will be exterminated. Evolution has never been a democracy. It respects neither human, animal nor vegetable rights.
We, though, have a vested interest. Our physical and economic well being is tied to the fate of many other species. For example bees, which the world over have been dying from a mysterious syndrome termed colony collapse disorder, or CCD, threaten enormous consequences. Experts at Cornell University in upstate New York have estimated the value bees generate in the US alone - by pollinating fruit and vegetable plants, almond trees and animal feed like clover - at more than $14 billion. In fact, animals provide pollination services for over three-quarters of the staple crop plants that feed human kind and for 90% of all flowering plants in the world. As Albert Einstein once put it, “no more bees, no more pollination, no more plants, no more animals, no more man.”
We are also endowed with a natural appetite for love and empathy. We abhor the waste of thousands of elephant lives in the service of our baser need to kill and our higher appreciation of beauty. We protect these “gentle giants” even when they destroy the livelihoods of peasant farmers who see nothing gentle in the behemoth’s manner. So I think a balance has to be struck between our role as nature’s hangmen and our compassion for those in her gallows.
Not all living things deserve our protection. And even if we wanted to, we could scarcely afford the investment it would take to save them all. We need a rationale for prioritizing which species to preserve and which to let go. Leakey declares that government policy should be based on the non-negotiable premise that “species which are the stuff of nature are priceless, as are human dignity and freedom.” While I definitely agree that human dignity and liberty are undoubtedly priceless, I think even he would have a hard time defending the priceless nature of the Ebola virus or the Guinea worm. The argument that viruses and other lethal parasites play a vital role in assuring our evolutionary “fitness” by eliminating weaker individuals is undercut by the acknowledged priceless nature of human dignity. It is a safe bet that theirs is a service that we would gladly do without.
My motto is: If the species is good for us then we save it. If it’s bad for us, then we kill it. If it doesn’t fall in either category, then it takes care of itself and good luck to it. Of course, this should not be taken as a license for extermination of all but the most obviously beneficial animals. Since we are often ignorant of future benefits of certain species, we need to hedge our bets through solutions that accommodate as many as possible without injuring our interests. All the same, we live in the present and while storing up for the future, let’s be careful we do not starve ourselves today.
That many organisms on this planet exist at our pleasure has been proven time and time again. And not just in regard to extinction. Through genetic tampering, we have created never-before seen specimens of cows, sheep, tomatoes etc. We have striven to eradicate any animal/plant that has posed a threat to our way of life. The smallpox bacterium and the saber-toothed tiger are just a few examples. Others we have locked up in zoos, reserves and parks for profit, academic study or just the joy of having them around as a kind of exotic pet. In a very real sense, we have been playing God for a long time. It’s about time we learnt to live and let die.
