What I’m saying is: if we do things, we do them for our own reasons. We shape nature to our own advantage. We don’t speak for nature and we don’t have any say in what’s best for nature, only what’s best for us.
Lots of people try to shelter their arguments from criticism by appeals to nature and that’s fallacious. Cooperation evolved by natural selection but it isn’t any more natural than competition. Arguably, competition is the more fundamental force in nature.
