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

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

I firmly believe that we can have a healthy environment and a sustainable timber industry.

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

We learned that economic growth and environmental protection can and should go hand in hand.

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!

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

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

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