" By this I do not mean the end of the world. The rain will still fall, and the sun will still shine. When I say “nature,” I mean a certain set of human ideas about the world and our place in it. But the death of these ideas begins with concrete changes in the reality around us, changes that scientists can measure. More and more frequently, these changes will clash with our perceptions, until our sense of nature as eternal and separate is finally washed away and we see all too clearly what we have done. "

― David Remnick , The Fragile Earth: Writing from The New Yorker on Climate Change
