I can trace my environmentally-friendly lifestyle back to my childhood. My father was a conservative Republican that liked to 'conserve'.

We run around so much - with the best intentions: I want to save the rain forest. I've gotta clean up the oceans. I've gotta save the dolphins. All worthy efforts, but if you're not centered and you don't have the serenity in your life you need to accomplish that task, you're not going to do a very good job.

People are overwhelmed looking up at the Mount Everest of environmental challenges that we face. But you put one foot in front of the other and you recognize that not everyone is Sir Edmund Hillary.

One of the regular intervals of meditation in my life, believe it or not, is in my car.

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.

California has always led the way on environmental protection and always reaped the benefits, pioneering everything from catalytic convertors on cars to stationary source reduction.

I'm a strong proponent of green tech for anyone who can afford it, having spent the last 40 years working toward achieving a smaller and smaller eco-impact for myself.
