It's naive to think that my eating vegetarian made a difference in the grand scheme. Much of what I ate was still requiring needless death and destruction of the environment--it just was invisible to me. Now I accept it, and try to eat from local farms (less fossil fuel waste), and organic (less destruction of the soil). I'm not going to risk affecting my health so that I can call myself a vegetarian. I think the most ecologically sound way of eating is to make your own food (hunting & killing it for carnivores, or growing it for vegetarians) yourself.
