The results are in: Californians aren’t saving enough water. Amid a historic drought, Gov. Gavin Newsom has asked us to reduce water consumption by 15 percent. Yet in August, the most recent month for which data is available, we’d brought usage down just 5 percent compared with the same time last year. Of course, not all water-saving is the responsibility of California households. Eighty percent of California’s water goes toward agriculture, and other businesses play a big role too.
