"As soon as I realized that I didn't need meat to survive or to be in good health, I began to see how forlorn it all is. If only we had a different mentality about the drama of the cowboy and the range and all the rest of it. It's a very romantic notion, an entrenched part of American culture, but I've seen, for example, pigs waiting to be slaughtered, and their hysteria and panic was something I shall never forget."
