I've been arrested three times. I don't like getting arrested, but it's not so bad when it's an organized form of nonviolent disobedience. It's something appealing to a higher law.

I think what we all have to do is make this big leap towards renewables. And it has to be a solution where you're actually building the answer; and it has to be built faster than the natural gas industry can build their answer.

I'm a night owl, and luckily my profession supports that. The best ideas come to me in the dead of night.

Every single dollar spent lobbying a legislator on behalf of oil and gas is a toxic dollar that undermines public health and safety laws that protect Americans. That's contamination of the political system.

Justice Scalia was a person who effectively bludgeoned the life out of the living Constitution, the Constitution that gave us desegregation, that gave us women's rights, that gave us environmental protections and political access.

I'm in this absolutely gorgeous manor house with acres of quite beautiful countryside. I've got trout in the river, an organic vegetable garden, I've got my work 40 yards from my home. I don't mind being criticised, but where are they criticising from? Which hut are they criticising me from, exactly?

Here in Canada, the people who oppose the tar sands most forcefully are Indigenous people living downstream from the tar sands. They are not opposing it because of climate change - they are opposing it because it poisons their bodies.

Is it 10 years, 20, 50 before we reach that tipping point where climate change becomes irreversible? Nobody can know. There's clearly a probability distribution. We need to ensure this planet, and we need to do it quickly.
