Look - every time is the wrong time and the perfect time to have a kid, and you just do it when you can.

When we work all over the planet, it's mostly poor and black and brown and young people, because that's mostly what the world [environmentalism] is.

According to new research emerging from many quarters that our continued devotion to growth above all is, on balance, making our lives worse, both collectively and individually

I imagine a certain amount of consumer impulse will be replaced by community connection. You can already see it starting with things like the local food movement.

I think the world on the other side of fossil fuel is more local - the logic of sun and wind is diffuse and spread out, not concentrated like the logic of coal and oil.

Scientists had said, "If you keep burning coal and gas and oil, you will melt the Arctic." And then the Arctic melted just as they had predicted. Did Shell Oil look at the melt and say, "Huh, maybe we should go into the solar-panel business instead?" No, Shell Oil looked at that and said, "Oh, well, now that it's melted it will be easier to drill for more oil up there." That's enough to make you doubt about the big brain being a good adaptation.

We, all of us in the First World, have participated in something of a binge, a half century of unbelievable prosperity and ease. We may have had some intuition that it was a binge and the earth couldn't support it, but aside from the easy things (biodegradable detergent, slightly smaller cars) we didn't do much. We didn't turn our lives around to prevent it. Our sadness is almost an aesthetic response - appropriate because we have marred a great, mad, profligate work of art, taken a hammer to the most perfectly proportioned of sculptures.
