The environment is everything that isn't me.

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.

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.

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

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.

I did not become a vegetarian for my health, I did it for the health of the chickens.
