The environmental crisis is a global problem, and only global action will resolve it.

By adopting the control strategy, the nation's environmental program has created a built-in antagonism between environmental quality and economic growth.

Earth Day 1970 was irrefutable evidence that the American people understood the environmental threat and wanted action to resolve it.

Everything is connected to everything else. Everything must go somewhere. Nature knows best. There is no such thing as a free lunch.

In certain ways, I'm not very different than I was when I was a teenager.

Our assaults on the ecosystem are so powerful, so numerous, so finely interconnected, that although the damage they do is clear, it is very difficult to discover how it was done. By which weapon? In whose hand? Are we driving the ecosphere to destruction simply by our growing numbers? By our greedy accumulation of wealth? Or are the machines which we have built to gain this wealth-the magnificent technology that now feeds us out of neat packages, that clothes us in man-made fibers, that surrounds us with new chemical creations-at fault?

Finally, since human beings are uniquely capable of producing materials not found in nature, environmental degradation may be due to the resultant intrusion into an ecosystem of a substance wholly foreign to it.
