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

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

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

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

It seems that every time mankind is given a lot of energy, we go out and wreck something with it.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

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.

I have a private plane. But I fly commercial when I go to environmental conferences.

We learned that economic growth and environmental protection can and should go hand in hand.

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