I have a lot of land. I bought it because I had a very strong feeling. I was in my early twenties, and I had grown up in Los Angeles and had seen that city slide off into the sea from the city I knew as a little kid. It lost its identity - suddenly there was cement everywhere and the green was gone and the air was bad - and I wanted out.

We've poisoned the air, the water, and the land. In our passion to control nature, things have gone out of control. Progress from now on has to mean something different. We're running out of resources and we are running out of time.

I was seen in earlier years by family members and people of authority as somebody wasting his time. I had trouble with the restrictions of conformity. It made me edgy.

I don't think you can ever return, really.

All my life I've been dogged by guilt because I feel there is this difference between the way I look and the way I feel inside.

I can't watch completed films - my wife makes fun of me.

The measure of our success will be the condition on which we leave the world for the next generation.
