Our choices at all levels-individual, community, corporate and government-affect nature. And they affect us.

Conventional economics is a form of brain damage.

The terrible part of this looming catastrophe is that people have been working on solutions for years and have developed concrete steps to massively reduce our energy use, while stimulating whole new industries and technologies that are more efficient and affordable.

One of the joys of being a grandparent is getting to see the world again through the eyes of a child.

We can't blame children for occupying themselves with Facebook rather than playing in the mud. Our society doesn't put a priority on connecting with nature. In fact, too often we tell them it's dirty and dangerous.

Even meeting Kyoto targets barely makes a dent in what we have to achieve.

We can no longer tolerate what's going on in Ottawa and Edmonton. What I would challenge you to do is to put a lot of effort into trying to see whether there's a legal way of throwing our so-called leaders into jail because what they're doing is a criminal act.
