I'm really changed by my research. This book ["This Changes Everything" ]is very different from what I set out to write.

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.

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.

Once you feel the desire to engage, think about what you're good at and what you can contribute. It's about breaking down the idea that there are activists and ordinary people.

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.

Catastrophic damage from climate-driven extreme weather is now an annual reality. The cost of not dealing with it will be much greater than if we try to pre-empt some of those disaster cleanups by actually investing in the shift now.

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.
