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.

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

It takes less land to grow a pound of broccoli than it does a pound of beef. Less land to grow a pound of grain than a pound of beef. Less water, less energy.

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

The film 'Tapped' illustrates quite clearly how we've been getting 'soaked' for years by the bottled water industry.

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.

California has always led the way on environmental protection and always reaped the benefits, pioneering everything from catalytic convertors on cars to stationary source reduction.
