Very few people on earth ever get to say: 'I am doing, right now, the most important thing I could possibly be doing.' If you'll join this fight that's what you'll get to say
But the truth is that we could win every other fight that we face and if we lose the climate fight, the other victories will be pyrrhic. I don't think even people who are worried about climate change quite understand the scale and speed with which we're now shifting the planet.
Here, there's more of a movement, it doesn't mean we're winning any more, but we're at least fighting.
There are many places where we need to fight important battles to make sure that customers have access to solar.
That's why people are standing up again to fight the Keystone pipeline in Nebraska and South Dakota and Montana. Everyone is well aware of what this industry is about. It engages not only in those kind of practices, polluting people's water, but it has polluted our political life now for a quarter century.
Do I think that people should in the best of all possible worlds have to go to jail for wanting the US government to pay attention to the warnings of scientists about climate change? Not really. I mean, in a rational world, if all the scientists said, "The worst thing that ever happened is about to happen and here's what you should do to stop it," you would expect any rational system to say, "Oh, sure, OK, let's do something about it." But that's not the world we live in. In the world we live in, you do need people willing to stand up, fight, march and sometimes go to jail.
We'd won the argument 15 years before, we were just losing the fight. And so it became clear to some of us that we would need to organise to fight, that we weren't going to win.
The fight around climate change, which I've spent my life on, is somewhat more difficult than gay marriages because no one makes trillions of dollars a year being a bigot, and that's how much the fossil-fuel industry pulls in pumping carbon into the air. But the principle is the same, I think.
These new technologies are not yet inevitable. But if they blossom fully into being, freedom may irrevocably perish. This is a fight not only for the meaning of our individual lives, but for the meaning of our life together.
Policies that engage us again in the international fight for real climate protection.
