Finally I have a chance to put my 5 cents in.
What a lot of people miss in this discussion is the fact that environmentalism has been used as an anti-capitalistic weapon by watermelons (green on the outside, red on the inside) for years. Nathan has a point: many an idea that were thunk up as the way of bettering the society brought destruction and death. It is not hard to imagine the coalition of "green" governments halting agricultural production in favor of "greener", more "earth-friendly" methods and starting world wide famine by doing that. No need to even become a totalitarian regime. Just keep appealing to populace who will keep electing Obama-like pawns.
