The quicker we humans learn that saving open space and wildlife is critical to our welfare and quality of life, maybe we'll start thinking of doing something about it.

I have a lot of memories of Falls Church. I went to grade school in Madison Elementary School.

Somali is turning into a desert. Rwanda, you can hardly find a place to plant a potato, it's so crowded.

The biggest challenge is how to affect public attitudes and make people care.

New York for me is about work. If L.A. were to become a West Coast version of that, I'd shoot myself. The climate, the lifestyle - it really fits as the yin to my New York yang.

We need to have a course in school that teaches about ecology and gastronomy. I could imagine that all children could eat at school for free and that the cafeteria would become part of the school's curriculum.

We can help companies committed to addressing global challenges such as climate change.

For all of the hurtling towards climate change, there's also a lot more understanding of it than there was when we were kids. They don't call environmentalists tree huggers any more, so there's hope!
