Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

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

When we realize we can make a buck cleaning up the environment, it will be done!

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.

I have a private plane. But I fly commercial when I go to environmental conferences.

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

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

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

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