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.

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.

When you're cornered, there are two things you can do: move or fight.

The aquifer [is] the water table people need to keep secure. Nature has this incredible system of water purification under the ground. Ground water is much better to drink than surface water because it filters out the bacteria that can cause all sorts of problems.

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.

In a couple of decades you have half of the wells that are drilled right now, and you're talking about numbers in the millions of wells drilled, leaking. That's a huge crisis in terms of water contamination. There's no way to fix that problem.

What we've got is the wholesale embrace of fracking domestically, internationally and for export. And this couldn't be further from what we really need to do to address climate change.
