We must realize that we're all part of a web of life around the world. Anytime you extinguish a species, the consequences are serious.

In the state of Wisconsin it's mandated that teachers in the social sciences and hard sciences have to start giving environmental education by the first grade, through high school

If we continue to address the issue of the environment where we live as though we're the only species that lives here, we'll create a disaster for ourselves

The most important environmental issue is one that is rarely mentioned, and that is the lack of a conservation ethic in our culture.

The issues are by some geometric number - 100 or 200 or 500 - times more complicated today than we appreciated them to be when Franklin Roosevelt was around.

All economic activity is dependent upon that environment and its underlying resource base of forests, water, air, soil, and minerals. When the environment is finally forced to file for bankruptcy because its resource base has been polluted, degraded, dissipated, and irretrievably compromised, the economy goes into bankruptcy with it.

We're going to have to do a whole lot more, and give nature at least a chance to repair some of the damage we've done.
