Even though I do like to tease my vegetarian friends with my statement above, my own diet has changed dramatically over the years. It now is far, far heavier in grains, vegetables, and non-red meats than it was, and those meats I do eat are eaten in much smaller quantities. And I prefer game to farm-raised meats, not because I want to kill things but because mankind has so screwed up the natural predator/prey relationship that to my mind it would be unethical NOT to hunt. Actually, I'd like it to be that you weren't allowed to eat any meat you didn't kill yourself, but that's not going to happen.

Consider, though, that what this society calls "vegetarianism" can actually be effective only in a culture with an efficient food distribution system. In the past, Springtime meant fresh green plants to eat and an end to Winter's scurvy-causing lack of vitamins (Arctic peoples dealt with it differently).
