Sometimes I think the Congress feels that if you only decided tomorrow to switch to wind power that in two years we'd be getting 80 percent of our electricity from wind power. It's nonsense. Normally it takes 20 to 30 years after a new technology is demonstrated and deployed before it powers even 15 or 20 percent of the grid. There's this long lag time, and we haven't even decided which directions to go.

I see harm reduction as a way of engaging people as part of that path to recovery.

There are lots of excellent analysts out there. John Holdren at the Harvard Kennedy School, who was just president of the American Association for the Advancement of Science, has been talking about this stuff for years. There are lots of people out there who understand what’s going on. The problem is, they aren’t much picked up on Fox News.

There's no question at all that the population explosion will come to an end. The two basic choices are it'll come to an end because we control our reproduction, and in many areas we have started to do so, or we'll end up with a high death rate. You have to take a personal moral stand on this.

Most of the scientists I know think civilization is teetering on the brink of a global disaster. They just don't know when it's going to hit. I don't have the answer to that either. I'm scared as hell.

I thought if the climate was heating that CO2 was the only forcing, and it would be late in the century before we had trouble. Now that we know about the other half of the forcing, it's obvious that the trouble is coming much sooner.

I don't like the idea of teaching religion in schools, and creation is not my thing, but that's a trivial point compared to saving the creation. I'd much rather have half of the people in the country be creationists and work really hard to save the creation than have everybody be evolutionists and be destroying the planet.
