If we do nothing, the ensuing climate catastrophe will wreck our economy - including wreaking havoc on our food production systems. All credible scientists agree on this point.

Sometimes we overemphasize the political system. There are other ways to make a difference. There's technology, there's media, there's business.

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.

I think that for those of us who come from oppressed backgrounds and who do our work in marginalized communities, recovering our innocence is one of the most important acts of self-liberation and de-colonization. Not letting the requirement that we adapt to impossible circumstances and unconscionable crimes leave us shackled to the kind of cynicism and armor such that we can't breathe and laugh and magnetize to ourselves all the genius and love and support that we need to transform the situation. That's probably the biggest challenge, is to recover our innocence.

There is great wisdom, there's great strength and there's great beauty in all of our religion, and those should be marshaled for good.

All the big ideas for getting us onto a lower carbon trajectory involve a lot of people doing a lot of work, and that's been missing from the conversation. This is a great time to go to the next step and ask, well, who's going to do the work? Who's going to invest in the new technologies? What are ways to get communities wealth, improved health, and expanded job opportunities out of this improved transition?

The question is: do we pay a little bit more now? Or do we pay a whole lot later? For the equivalent of a postage stamp a day for each American, we can put a price on carbon today that will send a signal to private capital to invest in the clean technologies of tomorrow. Taking a vast portfolio of new energy solutions to scale will ultimately drive down costs through competition.
