When we realize we can make a buck cleaning up the environment, it will be done!

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

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

Business has to change the way it does business, or we will make no significant changes in the way we relate to the earth.

If we were driving pure hydrogen automobiles, that automobile would actually help clean up the air because the air coming out of the exhaust would be cleaner than the air going into the engine intake.

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

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.
