Much of the debate over global warming is predicated on fear, rather than science.

Unless we keep this planet healthy, everything else is for naught.

I think the cost of energy will come down when we make this transition to renewable energy.

If we do not permit the earth to produce beauty and joy, it will in the end not produce food, either.

I can find God in nature, in animals, in birds and the environment.

The only way forward, if we are going to improve the quality of the environment, is to get everybody involved.

Keep close to Nature's heart... and break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.

The environment is everything that isn't me.

Unless we keep this planet healthy, everything else is for naught.

Harmony with land is like harmony with a friend you cannot cherish his right hand and chop off his left.
