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

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

We won't have a society if we destroy the environment.

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

People blame their environment. There is only one person to blame - and only one - themselves.

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

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

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

By polluting clear water with slime you will never find good drinking water.
