There are regulations all over the spectrum that have to be done to the existing situation right now. But the only policy that makes sense is a nationwide moratorium: no new fracking, no new fracked wells.

I don't believe we're only motivated by our own self-interests. Often out of crisis comes this enormous wellspring of generosity and motivation.

It is an incredibly hopeful experience watching communities come together and actually reassemble democracy. The democracy's been taken away from us. But they're reinventing democracy out there in rural Pennsylvania, in Philadelphia, in Pittsburgh.

I think we're in an era of unprecedented dominance by corporations. I think people understand that deeply; I don't think that's even questioned.

When you frack a well, you're exploding methane up into the atmosphere. So, Barack Obama, by supporting natural gas, and also talking about climate change is literally burning his own inaugural address. And he's doing it with natural gas.

I have to have faith that we're going to succeed in transforming where we get our energy from. The big worry is whether or not we're going to do it before it's too late. And I think nobody knows the answer to that.

There's something really happening and really moving, and it's exciting and it makes me very optimistic because it is going to be the engine for how we really combat climate change. Which is strong communities.
