As many know, the Chinese expression for "crisis" consists of two characters side by side. The first is the symbol for "danger," the second the symbol for "opportunity."

Having worked on climate crisis for almost 40 years now, I've seen good days and bad days. And through all of that time, the general trajectory has been it's getting worse, it's getting worse. But in the last ten to 20 years, there's a second development; the solutions are more and more, and more available. So having this broad overview that I've developed over a long period of time, I now see the evidence that the solutions are available. We're gonna do this.

Having cameras follow you is something that requires a little personal adjustment, but you actually do begin to forget they're there. It's impossible to maintain that awareness all the time, and when you're going through an emotional or absorbing experience, you really don't have any spare attention to think, "Got to remember that the camera is rolling."
