For my own health, I thought it was better to eat a plant based diet. I'm going to be 60 soon and I have boundless energy and I feel really good, so I'm all for it.

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.

I ride my bike for transportation a great deal - occasionally I ride it for fun. But I also have a generator bike that's hooked up to my solar battery pack, so if I ride 15 minutes hard on my bike, that's enough energy to toast toast, or power my computer.

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.

I've been in movies with Meryl Streep, Jack Nicholson - but I was on 'The Simpsons,' and finally, in the eyes of my children, I was a star.

I wanted to be an actor my whole young life. My dad was an actor, obviously - he won an Academy Award, but I had no idea what was involved. I had all the wrong ideas about acting.

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