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

The environment is everything that isn't me.

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.

Local innovation and initiative can help us better understand how to protect our environment.

No one should be able to enter a wilderness by mechanical means.

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

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

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.

The only way forward, if we are going to improve the quality of the environment, is to get everybody involved.
