If you spend a lot of time with activists, as I have, they're just ordinary people who instead of Netflix are getting together in church basements and making posters or making phone calls doing organizing work. It really is about finding a community of other people.

The thing that our system is designed to do is keep us alone and isolated in our little consumer bubble. And the most revolutionary act of all might be finding a community of like-minded people where you can talk about these issues and figure out what to do together.

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.

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.

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.

I've always kind of hated films about climate change.

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