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

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

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

Birds are indicators of the environment. If they are in trouble, we know we'll soon be in trouble.

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.

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

The environment is everything that isn't me.

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

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.

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