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.

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

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

What we face in Canada are multiple overlapping crises. We have the climate crisis, which is screaming down on us - all of the predictions are coming true even faster than the scientists thought. We have the inequality crisis, where the Panama Papers are a great reminder that the one per cent have actually created their own economy. We still have the crisis of child poverty, which has never been dealt with despite decades of concerned words from politicians.

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.

One of the things that could be exciting about this next phase of Canadian politics is if we could maybe have co-leaders.

The United States had eight years of Barack Obama. He made it incredibly clear that he was a right-wing Democrat. He cited Ronald Reagan lovingly in every stump speech for the last six months of the presidential 2008 campaign. And he made it clear that he was going to be a business-friendly Democratic president, and that he was not going to rock the neoliberal boat. And he didn't.
