meat doesn't "feed the world," though. the meat industry in america is huge because americans insist on eating meat 3 times a day. in most parts of the world, meat is eaten once a day, at most, and even then serving sizes are far smaller than americans. the meat industry isn't solving world hunger, it's filling the bellies of rich americans who could afford to purchase responsibly raised meat if they were a) educated and b) cared enough about their health/diet to spend more money on groceries and less on TVs/cars/video games/etc.
