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

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

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.

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

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

We don't have to sacrifice a strong economy for a healthy environment.

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

It seems that every time mankind is given a lot of energy, we go out and wreck something with it.

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

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