This is what Daniel Quinn calls "living in the hands of the gods". We are not really fit to do anything else. Humans have survived for hundreds of thousands of years living off what the land provides them in its natural course. Civilization will probably not make it much past ten thousand years, if that.
So tell me again which is the bigger nightmare: living and dying according to the whims of nature, being one small part in a society that adapts and harmonizes to nature; or the death of billions, and the extermination of considerable amounts of other life, all because we wanted to rule in place of the gods and never learned not to shit where we eat.
