I have a very low regard for cynics. I think it's the beginning of dying.

Any time I saw people treated unfairly because of race, creed, whatever - it struck a nerve.

Between 18 and 19 years old [in the 1950s] I came to Paris. I studied art. And that experience really did change my life. I was living hand to mouth. I walked everywhere. I thought, this city is incredible but you really have to experience it by walking it.

I would see my hometown, Los Angeles, change. Green space and orange groves gave way to cement, freeways flooded with traffic, and air pollution, all in the name of "progress." I felt like I was losing my home. It had a profound effect on me, and I realized just how important nature was to my spirit, my soul, my point of view.

It's all about greed and money and it's the driving force in Hollywood.

People are finally able to look around and say, 'I can see the drought, I can see the rising sea levels, I can see the crops dying. Okay, now I get it.' It is finally beginning to sink in that there has been a lot of damage.

I try to avoid giving advice. The only advice I will give is to pay attention. I don't mean to the screen in your hand. I'm talking about the natural world. I spent a lot of time educating my children about nature by putting them in nature. I said, "I want you to listen; I want you to look." There's so much technology coming into our lives that takes us away from the natural stuff, so I'm pushing the other way.
