I think it's crazy for us to play games with our children's future. We know what's happening to the climate, we have a highly predictable set of consequences if we continue to pour greenhouse gases into the atmosphere.

My father left me with the feeling that I had to live for two people, and that if I did it well enough, somehow I could make up for the life he should have had. And his memory infused me, at a younger age than most, with a sense of my own mortality. The knowledge that I, too, could die young drove me both to try to drain the most out of every moment of life and to get on with the next big challenge. Even when I wasn't sure where I was going, I was always in a hurry.
