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

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

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.

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

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

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.

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