I think fracking for gas will reduce the incentive to turn to renewables, and I think it will do a lot of other damage across the countryside.

There's a part of all of us whose impulse is to say, "Let's keep everything the same until I die and then you can do whatever you want afterward." And that's a difficult part.

Absent the net, we certainly couldn't have organized in 190 countries around the world. It's no substitution for face to face interaction - that's why we have "days of action" where people are in real contact with each other - but it's the cheap (and low-carbon) way to do an awful lot of the planning and organizing. And we can build, for $20k, a website as good as one Exxon can build for $20 million.

Global warming is no longer a philosophical threat, no longer a future threat, no longer a threat at all. It's our reality.
