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

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.

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

I bought my first electric car in 1970. Its top speed was 15 mph and it had just a 15 mile range - it was essentially a golf cart with a windshield wiper and a horn.

I've lived a slower and less expensive life going off the grid, and I'm happier because of it.

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.
