I think Canada deserves a forthrightly left electoral alternative. I don't see the advantage for our democracy in having a number of parties crowded in the centre. The Liberals are experts at co-opting left language and framings during campaigns, and historically, we know they don't govern like that.

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.

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

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

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.

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.

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.
