The earth is a tremendous gift. There is nothing else like it in the known universe. I want to leave it the way I found it.

It's fun to be a little bit different in the world, to make a few new trails of your own.

We're the only species that have crapped up the planet and the only species that can clean it up.

The premise is simple: One economy and one environment, and they're interdependent.

But the "wise" person understands something else— that we are all connected and, therefore, his or her own happiness must include the happiness of others.

There can be no lasting peace, no security, nor can we as human beings begin to touch our full potential, as long as hunger overwhelms the human spirit around this planet.

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