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.

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

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

Take a course in good water and air and in the eternal youth of Nature you may renew your own. Go quietly, alone no harm will befall you.

No one should be able to enter a wilderness by mechanical means.

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

Never doubt that a small group of thoughtful, committed citizens can change the world indeed, it's the only thing that ever has.

You may be able to fool the voters, but not the atmosphere.

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

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