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.

We're not living in a society that science actually dominates the conversation. We're living in a situation where some science is allowed and a lot of it's about policy.

When the natural gas industry was knocking on my door, they were knocking on the door of millions of people. And that became something that Americans really needed to focus on.

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.

Every single dollar spent lobbying a legislator on behalf of oil and gas is a toxic dollar that undermines public health and safety laws that protect Americans. That's contamination of the political system.

Natural gas is a bridge fuel. But it's not a bridge - it's a gangplank. It's either a bridge in space or a bridge in time. The bridge in time we don't need. We have renewable technology right now.
