Sometimes I feel like there isn't enough Prozac in the world to make Environmental Protection Agency people feel better about their jobs. They're going out there, they're trying to protect Americans and then time and time and time again they get their knees cut off at the policy level.

They're a lot of great scientists and their mission is to protect people. It's the Environmental Protection Agency, but it's really a people protection agency. And they're out there trying to do their job and do the science.

The first line in the first Gasland is: “I’m not a pessimist. I’ve always had a great deal of faith in people that we won’t succumb to frenzy or rage or greed. That we’ll figure out a solution without destroying the things that we love.” I have not lost that sense.

When you live in a watershed area, in a pristine area, and you could watch this whole place fall apart in front of your eyes, you don't sell your soul for a buck.
