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.

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

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

The environment is everything that isn't me.

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.

I think the cost of energy will come down when we make this transition to renewable energy.

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

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