We should be moving vigorously towards renewable energy. The technology of which is right here right now.

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.

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.

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 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.
