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.

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

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.

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.

You can't just do one of the things, because it won't be enough to combat the climate change that we're already starting to experience. It will only get worse.

We have lots of other problems with plastic in our oceans. There are five different big gyres of plastic out in the ocean. There are problems with air pollution around the country that we need to deal with, and around the world. We have a great many problems to overcome, so I work on a lot of different boards trying to help in those important areas.
