A Quote by E. O. Wilson

Look closely at nature. Every species is a masterpiece, exquisitely adapted to the particular environment in which it has survived. Who are we to destroy or even diminish biodiversity?
Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.
Each of these [bacterial] species are masterpieces of evolution. Each has persisted for thousands to millions of years. Each is exquisitely adapted to the environment in which it lives, interlocked with other species to form ecosystems upon which our own lives depend in ways we have not begun even to imagine.
To many people, 'biodiversity' is almost synonymous with the word 'nature,' and 'nature' brings to mind steamy forests and the big creatures that dwell there. Fair enough. But biodiversity is much more than that, for it encompasses not only the diversity of species, but also the diversity within species.
We are the most dangerous species of life on the planet, and every other species, even the earth itself, has cause to fear our power to exterminate. But we are also the only species which, when it chooses to do so, will go to great effort to save what it might destroy.
As far as life is concerned, there is no such thing as "Nature". There are only homes. Home is that environment to which the individual has become adapted; and almost everything is unnatural outside his range of adaptation. Harmonious equilibrium with nature is an abstract concept with a Platonic beauty but lacking the flesh and blood of life. It fails, in particular, to convey the creative emergent quality of human existence.
Of which beauty will you speak? There are many: there are a thousand: there is one for every look, for every spirit, adapted to each taste, to each particular constitution.
At last gleams of light have come, and I am almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable. Heaven forfend me from Lamarck nonsense of a 'tendency to progression', 'adaptations from the slow willing of animals', &c! But the conclusions I am led to are not widely different from his; though the means of change are wholly so. I think I have found out (here's presumption!) the simple way by which species become exquisitely adapted to various ends.
Are we at some kind of evolutionary equipoise as a species? Or, are we destined to become something different - something, perhaps, even better adapted to the environment?
What nature does in the course of long periods we do every day when we suddenly change the environment in which some species of living plant is situated.
Animals form an inalienable fragment of nature, and if we hasten the disappearance of even one species, we diminish our world and our place in it.
Very few species have survived unchanged. There's one called lingula, which is a little shellfish, a little brachiopod about the size of my fingernail, that has survived for 500 million years, but it's survived by being unobtrusive and doing nothing, and you can't accuse human beings of that.
We have a very old conservation movement, particularly in the United States, which has focused on campaigns to protect endangered species: the spotted owl, the old-growth forest. But usually it stops there. To me, biodiversity is the full spectrum. Species conservation is not only about wilderness conservation. It?s also about protecting the livelihood of people even while changing the dominant relationship that humans have had with other species. In India, it?s an economic issue, not just an ecological one.
Humanity is part of nature, a species that evolved among other species. The more closely we identify ourselves with the rest of life, the more quickly we will be able to discover the sources of human sensibility and acquire the knowledge on which an enduring ethic, a sense of preferred direction, can be built.
Every species has come into existence coincident both in space and time with a pre-existing closely allied species.
Humans, like all other creatures, must make a difference; otherwise, they cannot live. But unlike other creatures, humans must make a choice as to the kind and scale of difference they make. If they choose to make too small a difference, they diminish their humanity. If they choose to make too great a difference, they diminish nature, and narrow their subsequent choices; ultimately, they diminish or destroy themselves. Nature, then, is not only our source but also our limit and measure.
Species evolve to meet the environment. An intelligent species changes the environment to suit itself. As soon as a species becomes intelligent, it should stop evolving.
