I have nothing against polar bears, of course. But the polar bear is just a brown bear which has evolved to live in an arctic environment. If global warming does eliminate the polar bear’s habitat, it will be to make room for more brown bears. Is there a reason why we should prefer polar bears over brown bears? Perhaps its because polar bears are one of the few large animals which can survive in the arctic. But this only demonstrates that the arctic environment is relatively unfriendly towards life.
