Many of today’s social movements, like the industries they seek to revolutionize, must make big changes quickly—which is best accomplished by directing efforts upward toward institutions. I call this vertical agitation. The Santa Fe Reporter listed the top ten commercial water users, in addition to the top ten households. The first of these offenders, the city of Santa Fe, used 195 times more water than the number-one household offender. Imagine the relative difference in getting the city to commit to water-saving techniques as compared to reforming a single household.

Recall that in our early evolution we could gauge cooperation only first-hand. As group size got bigger, and ancient humans grappled with issues of necessary cooperat
