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.

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

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

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.

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

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

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

Local innovation and initiative can help us better understand how to protect our environment.

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.
