A green economy begins to replace some of the clunking and chugging of ugly machines with the wise effort of beautiful, skilled people. That means more jobs.

The time has come to move beyond eco-elitism to eco-populism.

A lot of liberals think all the Trump voters are a part of the alt right, neo Nazi camp, which is not true. That's a tiny, tiny slice.

Back in 2007, I met this white guy [director Peter Byck] with a lot of hair and a video camera, at a conference that I happened to be attending for the launch of an organization called Blacks in Green. I had never heard of him and Peter had never heard of me. We just started talking; he liked what I had to say, so he asked me if I'd be willing to be in this documentary he was doing about carbon pollution. I said, "Sure!" It was kind of a no-brainer.

Local politics matters a lot.

Though the rampant racial injustices throughout the criminal justice system were offensive to me and to millions of other people, I've never drawn a tight circle around the black community to define the limits of my moral concern. But that narrative tends to get imposed on you, if you're an African-American activist.

Even if we can solve the carbon problem for coal, it is still a non-renewable resource. At some point, coal supplies will drop.
