"Vegetarianism is my religion. I became a consistent vegetarian some twenty-three years ago. Before that, I would try over and over again. But it was sporadic. Finally, in the mid-1960s, I made up my mind. And I've been a vegetarian ever since. ... This is my protest against the conduct of the world. To be a vegetarian is to disagree—to disagree with the course of things today. Nuclear power, starvation, cruelty—we must make a statement against these things. Vegetarianism is my statement. And I think it's a strong one."
