I think there will come a time when civilized people will look back in horror on our generation and the ones that have preceded it; the idea that we should eat other living things running around on four legs, that we should raise them just for the purpose of killing them! The people of the future will say 'meat-eaters' in disgust and regard us in the same way that we regard cannibals and cannibalism.

We don't have to sacrifice a strong economy for a healthy environment.

Years ago on the set of Gunsmoke I read the book The Holy Science. Since then I have not eaten meat.

I feel responsible; I feel I've got to do something that will leave the kids a place where they can live healthy, safe, productive, creative and prosperous lives.

Practically every environmental problem we have can be traced to our addiction to fossil fuels, primarily oil.

There can be no lasting peace, no security, nor can we as human beings begin to touch our full potential, as long as hunger overwhelms the human spirit around this planet.

The premise is simple: One economy and one environment, and they're interdependent.
