Your missing the part where dinosaurs died out, 3 different times. They didn't just evolve into birds because modern day birds are some higher form of evolution. And the rat/mouse/rodent just globally spread on the backs of whales? And if nature is perfect, and we are part of nature, then how can it be claimed we are destroying the earth? So either nature is not perfect since we came of it, or humans are not destroying the earth? Which is it?
