Listen up, you couch potatoes: each recycled beer can saves enough electricity to run a television for three hours.

We shouldn't fuel the future with the polluting methods of the past, ... We have the technology to power our future in ways that don't threaten our health or poison our planet. Let's choose to use it.

Build high-speed, electrified trains over the most-traveled corridors. It'sreally hard to power carbon-free airplanes, but electrified trains are much easier. We'll be a half century behind the Japanese, but better late than never.

The easiest way to make something cool is to get cool people to do it. Part of this might mean the president has to forget tensions with opponents, or people like Arnold Schwarzenegger who has actually been decent with oil issues. Maybe he needs to pull some of the cool people in and make them model the right behaviors.

Politicians had always viewed environmental issues as narrow things of no great political consequence. Sort of NIMBY issues. A big part of the reason was that the groups that cared about wilderness didn't talk with the groups that were trying to stop freeways from cutting through inner cities, and neither of them talked to the folks who wanted to stop the military from dumping Agent Orange on Vietnam.

I feel more confident than ever that the power to save the planet rests with the individual consumer.

It is already too late to avoid mass starvation.
