Well, it doesn't have to go to that degree, just be aware of where your food is coming from. Most decent-sized cities here will have butchers that only receive their stock from humane farms, and some even get their stock from local hunters if everyone has the appropriate licenses. Their prices are higher, of course, but that's fine - it's a luxury, and it's kind of neat to go in and buy some venison that was, uh, "harvested" by a local hunter.
