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.

The environmental crisis is all a result of rushing.

It takes less land to grow a pound of broccoli than it does a pound of beef. Less land to grow a pound of grain than a pound of beef. Less water, less energy.

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.

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.

This is a deeply spiritual issue...Do we want to spend more time trying to care for our fellow man or do we want to just pursue more virtual reality? That's the issue before us.. and it's being played out in the world of the environment.

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