i was thinking about like... keeping cows for milk being made illegal due to the methane, so 'volunteers' are locked up and fed a mixture of feed and hormones 'til their udders come in. the sideeffect is that all of these volunteers end up gaining sigificant amounts of weight b/c of how much they're being fed. their udders coming in varies based on willpower & biology, when they finally do they're hooked up and milked. it's identical to cow's milk, but since it's not coming from cows, it's technically legal until bureaucracy does something about it. blahblah
