People don't want to change. It's hard for people to change and it's hard for businesses to change. If I was running an oil company, I would be resistant to change too.

To be a modern person in 2012, you are often required to have some electronics in your life. And I do. I try to put that phone down, put the computer away, and get out there and hike in the woods; feel it in my feet, feel it in my hands; get out in the garden and feel the soil under my fingers, my fingertips and my fingernails. I try to be involved in nature in a very tactile way. I think that's important.

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.

The environmental crisis is all a result of rushing.

There are many different ways now to experience nature. Get out there and hike.

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

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.
