When you have solar panels, your electricity gets there for free, no one's figured out how to meter the sun yet. And that's good.

The idea that China and India will just abandon climate action is not true, because they're doing it for more reasons than we are.

I think we need to think of lots of ways to communicate. And we tried some at 350. We organised what they called the largest art project in the planet's history. We do a lot with art and music and things.

what sets wilderness apart in the modern day is not that it's dangerous (it's almost certainly safer than any town or road) or that it's solitary (you can, so they say, be alone in a crowded room) or full of exotic animals (there are more at the zoo). it's that five miles out in the woods you can't buy anything.

The consumer culture in general has washed over our civilization. For the last 50 years, if you've had a credit card and some access to money, you don't really need neighbors around you. And as a result, they dwindled. The average American has half as many close friends as they did in 1950. Three quarters of Americans don't know their next-door neighbor. They may know their name, but they have no real relationship with them. That's an utterly new place for human beings to find themselves in - I mean, we're a socially evolved primate.
