If you're going to drive a Hummer and buy carbon offsets, that's like getting drunk every night and getting into an AA meeting, throwing money in the basket, and leaving.

It's something I passed on to my kids. They really love the earth because they've experienced it from the youngest age. They know where food comes from - it doesn't come from the Safeway bush or the Ralph's tree. It comes from the earth. And water and sunshine and nutrients. My children understand that because they've experienced it. I feel successful as a parent, having done that.

As someone who has grown up living in Southern California, I know all too well about the costs and scarcities of water.

By 1990 I went back to no gasoline; I was just riding around on my bike, taking the bus. I had a tiny little electric car that didn't go very far or very fast. People thought I'd lost my mind. Even my own family thought I'd lost my mind.

Experience nature. Then you know why it's worth protecting.

I'm not a wealthy person because I was never a star. I was a working actor and a supporting actor.

My favorite form of transportation is walking. I live in a neighborhood where you can walk to restaurants, banks, and shops.
