Gaylord Nelson

Teddy Roosevelt of course was a great outdoorsman all his life.

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

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.

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.

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.

Loads of chemicals and hazardous wastes have been introduced into the atmosphere that didn't even exist in 1948. The environmental condition of the planet is far worse than it was 42 years ago.

Franklin Roosevelt was very concerned about environmental issues.
