I am against genocide, or "euthanasia" for the sake of population control (I am in favor of assisted suicide in the case of terminal illness). However, I think "Chinese-style" population control is one of the few hopes for the future we have. The planet needs about 1/2 of it's current population to remain viable.
As for the rest of your post *sigh* ... y'know plunkey, you remind me of my ex-husband so much it makes my skin crawl. You simply exhaust me. When he had a disagreement with me he would pull apart every opinion with the precision of a vivisectionist. I would have to justify every single word of every single point. Maybe that's one reason why the rich and powerful get where they are, they just wear the rest of us down until we go "Fine, whatever, you win just please STFU." I used to cheat to lose when I played board games with my ex because he was such a sore loser, your arguments remind me too much of his desperate need to ALWAYS be RIGHT.
You're right about one thing though, industrial farming, particularly the wholesale pollution of groundwater and soil that comes with it, is major issue. Organics has it's own set of issues but unlike you, I don't know the solution, all I can say is we're doing something very, very wrong, America in particular. By the same token, pointing fingers and saying "what about their mess, what about that mess?" doesn't solve anything, even though it's all the world leaders keep doing. Everyone just STFU and agree on fixing shit, even if that means taking a financial hit. People need to stop making everything about ledger sheets, but greed usually trumps common sense and foresight.
