" We people are just like our planetmates. We cannot put an end to nature; we can only pose a threat to ourselves. The notion that we can destroy all life, includng bacteria thriving in the water tanks of nuclear power plants or boiling hot vents, is ludicrous. I hear our nonhuman brethren snickering: "Got along without you before before I met you, gonna get along without you now", they sing about us in harmony. Most of them, the microbes, the whales, the insects, the seed plants, and the birds, are still singing. The tropical forest trees are humming to themselves, waiting for us to finish our arrogant logging so they can get back to their business of growth as usual. And they will continue their cacophonies and harmonies long after we are gone. "
