There is no evidence that socialism (the variety that actually exists in the real world and not in your head) is any more ecologically friendly than capitalism.

I think it's deeply sad that you haven't learned the lessons of the 20th century. "Gentle measures" are the only way to make progress, we can't sever our connection to the past, drastic measures of the kind you're proposing have always resulted in the vivisection of actual human communities based on a quasi-religious understanding of what's going to happen in the future.
