Thank you for reading, @marcoriccardi!

I think a lot about plastics ... we try hard in San Francisco to control our plastic use and recycle, but if there were massive sea level rise, there would just be no ordinary way to deal with the problem because so much plastic is already out there. I also think about what it would take to make my home country stop acting crazy around race -- it would take a disaster about this big. Yet I wasn't trying to be too grim -- I laughed as I was writing parts of it, and I'm glad that came through!
