I'm not a vegetarian, but I have cut back sharply on the meat that I eat.

I am a passionate advocate of getting special interest money out of politics.

The golden thread of reason that used to be stretched taut to mark the boundary between the known and the unknown is now routinely disrespected.

I'm passionate about restoring the efficacy of American democracy, making capitalism sustainable, prioritizing advances in technology, and seizing the opportunities to use that kind of innovation to help usher in a new economy that doesn't rely on carbon-spewing fossil fuels.

I think that more diversity is a good thing, and fresh points of view articulated by people who are committed to excellence in journalism is a beneficial change in the American media landscape.

I don't have the illusion that there's any position or role in the world with as much potential for bringing about change as that of president of the United States.

I have felt for a long time that the pathway to solving the climate crisis is through the building of a massive grassroots army of men and women who will go out there and win the conversation on climate, and persuade businesses, and universities, and towns to switch to renewable energy and to reduce emissions. And the big change from ten years ago is that people are way more receptive, not only to the message that we have to act, not only to the message that now we can act, we have the solutions now - that's the biggest change - but also willing to make a commitment that we will act.
