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.

If we had a hydrogen economy worldwide, every nation on earth could create its own energy source to support its economy, and the threat of war over diminishing resources would just evaporate.

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

The people of the future will say, 'meat-eaters!' in disgust and regard us in the same way that we regard cannibals and cannibalism.

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

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.

Whatever we'll be forced to do later, we should be doing now.
