To be a modern person in 2012, you are often required to have some electronics in your life. And I do. I try to put that phone down, put the computer away, and get out there and hike in the woods; feel it in my feet, feel it in my hands; get out in the garden and feel the soil under my fingers, my fingertips and my fingernails. I try to be involved in nature in a very tactile way. I think that's important.

It's people wanting to do something about global climate change. People fed up with the high price of gas. People tired of breathing dirty air. In Houston, Los Angeles, Bakersfield, and other cities. It's going to be a critical mass of people experiencing something.

The two most abundant forms of power on earth are solar and wind, and they're getting cheaper and cheaper.

As someone who has grown up living in Southern California, I know all too well about the costs and scarcities of water.

By 1990 I went back to no gasoline; I was just riding around on my bike, taking the bus. I had a tiny little electric car that didn't go very far or very fast. People thought I'd lost my mind. Even my own family thought I'd lost my mind.

I'm a strong proponent of green tech for anyone who can afford it, having spent the last 40 years working toward achieving a smaller and smaller eco-impact for myself.

This is a deeply spiritual issue...Do we want to spend more time trying to care for our fellow man or do we want to just pursue more virtual reality? That's the issue before us.. and it's being played out in the world of the environment.
