Vegetarian diet somehow equals synthetic sludge and nothing to hope for?! Sorry if that mischaracterizes your point, but it does seem that's the slippery slope you were going for.
I regularly hear people saying the earth could support x billion people if we all just adopted diet y.
Is it really our ambition to turn the whole world into residential skyscrapers just because we figured out how to feed 40 billion people on this one planet?
