We had other currencies that we could find work in - the currencies of movements: passion, spirit, creativity.

I did very much like [Barack] Obama's attack on fossil fuel subsidies for fossil fuel companies. We asked for that in demonstrations and petitions, and now we'll try to push it forward.

We can either save the planet from catastrophic warming, or protect fossil fuel CEOs. Not both. Do the math(s)

Here, there's more of a movement, it doesn't mean we're winning any more, but we're at least fighting.

We, all of us in the First World, have participated in something of a binge, a half century of unbelievable prosperity and ease. We may have had some intuition that it was a binge and the earth couldn't support it, but aside from the easy things (biodegradable detergent, slightly smaller cars) we didn't do much. We didn't turn our lives around to prevent it. Our sadness is almost an aesthetic response - appropriate because we have marred a great, mad, profligate work of art, taken a hammer to the most perfectly proportioned of sculptures.

The fact that Washington has been a complete logjam for anything for the last six years has got to change because we need to have federal policy that really allows us to move quickly and nimbly.

Do I think that people should in the best of all possible worlds have to go to jail for wanting the US government to pay attention to the warnings of scientists about climate change? Not really. I mean, in a rational world, if all the scientists said, "The worst thing that ever happened is about to happen and here's what you should do to stop it," you would expect any rational system to say, "Oh, sure, OK, let's do something about it." But that's not the world we live in. In the world we live in, you do need people willing to stand up, fight, march and sometimes go to jail.
