I think people are losing that sense of security pretty fast, frankly.

The book and the film [This Changes Everything] fed into each other in ways that were compounding and very exciting. The pain was shared.

Film 'This Changes Everything' is not a sad story. It's not a slit-your-wrists climate film. It's a story about people who are making change happen.

If you have a culture based on hunting and fishing and all the animals are disappearing and the fish are sick, then you can't live traditionally. Then your treaty is being violated. Obviously there are degrees of choice in terms of that decision to fight.

Find an organization, shoot them an email, call them up, find them on Facebook and say "Hey, I want to volunteer." And that first step could lead to a whole life of engagement. It could be a pretty exciting ride.

So many people are on the front lines of this fossil fuel frenzy. It is infused with a sense of urgency.

I personally feel very strongly that what it will take is not more disasters, it's that what it will take is a vision of the future that is better than our present.
