Yesterday, I tried to convince my son to shorten his shower because of California’s drought. He was unmoved. Maybe because he knows showers are not the big problem. Several of those problems are described by Eric Holthaus in Slate: 10 Percent of California’s Water Goes to Almond Farming. (This morning, I caught my son eating almonds in the shower.)

+ Quartz: If Californians want to really conserve water, they should cut down on coffee, rice, and beef. We should also set up a secondary market where California entrepreneurs can exchange startup equity for drinking water.
