Species Extinction Quotes
I am fully convinced that species are not immutable; but that those belonging to what are called the same genera are lineal descendants of some other and generally extinct species, in the same manner as the acknowledged varieties of any one species are the descendants of that species. Furthermore, I am convinced that natural selection has been the most important, but not the exclusive, means of modification.
Charles Darwin
Of the four billion life forms which have existed on this planet, three billion, nine hundred and sixty million are now extinct. We don't know why. Some by wanton extinction, some through natural catastrophe, some destroyed by meteorites and asteroids. In the light of these mass extinctions it really does seem unreasonable to suppose that Homo sapiens should be exempt. Our species will have been one of the shortest-lived of all, a mere blink, you may say, in the eye of time.
P. D. James
Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.
Al Gore
Something will have gone out of us as a people if we ever let the remaining wilderness be destroyed; if we permit the last virgin forests to be turned into comic books and plastic cigarette cases; if we drive the few remaining members of the wild species into zoos or to extinction; if we pollute the last clear air and dirty the last clean streams and push our paved roads through the last of the silence . . .
Wallace Stegner
I think it inevitably follows, that as new species in the course of time are formed through natural selection, others will become rarer and rarer, and finally extinct. The forms which stand in closest competition with those undergoing modification and improvement will naturally suffer most.
Charles Darwin
to stop for just a moment and think about what this war could mean. For human beings. We almost went extinct fighting one another before. Now our numbers are even fewer. Our conditions tenuous. Is this really what we want to do? Kill ourselves off completely? In the hopes that-what? Some decent species will inherit the smoking remains of the earth?"We can't fight one another"-"there won't be enough of us to keep going. If everybody doesn't lay down their weapons-"Yes. I'm calling for a...
Suzanne Collins
Life is insanely robust, though we can make species go extinct, and this is the bad thing. So I always make the point that you can't say, 'Is it too late?' That is the terrible question, because either answer promotes inaction. If it's too late, you don't need to act; if it's not too late, you don't need to act.
