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.

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

We are letting the extractive energy industries turn the world inside out.

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.

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.

The problem is that everywhere the gas drilling industry goes, a trail of water contamination, air pollution, health concerns and betrayal of basic American civic and community values follows.

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.
