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

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

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

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

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

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

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

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

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