Y'know the great thing about nature? It's the original conservative. It takes care of itself...naturally.
I don't ascribe to that belief. Nature doesn't care if the planet is sterile. There is a chapter in my book that deals with this specific issue and concludes that it is a Type II error. It is based upon a tautological logic; i.e., that Nature is whatever it becomes because it does so without human intervention, as if humans are not a seamless component therein.
Isn't it fascinating that those who accept the observable fact of natural selection and then leap to the doctrinaire belief in evolution to the exclusion of any other logical theory, then separate humans from that system in their preferred policies as if all we could do is harmful. Perhaps this is the gaian articulation of original sin.
