I am being very humble about the Arab Spring. There's kind of a competition out there, you might have noticed, of who can be the first to say the Arab Spring is going to fail. Everyone says, "I told you so, I told you so about the Muslim Brotherhood." I have no desire to tell anyone anything. I don't know. I'm just listening, watching.

At the end of the day, no amount of investing, no amount of clean electrons, no amount of energy efficiency will save the natural world if we are not paying attention to it - if we are not paying attention to all the things that nature give us for free: clean air, clean water, breathtaking vistas, mountains for skiing, rivers for fishing, oceans for sailing, sunsets for poets, and landscapes for painters. What good is it to have wind-powered lights to brighten the night if you can't see anything green during the day? Just because we can't sell shares in nature doesn't mean it has no value.
