Matt Damon on a bathroom strike to benefit the environment

Remember a few years ago when Gisele Bundchen and Tom Brady asked people to turn off the lights during Earth Hour? Well, Matt Damon is doing something of the sort, but with a sense of humor. In a tongue-in-cheek video launching on YouTube on Tuesday, Damon announces that he won’t use a restroom until everyone on Earth has clean water and sanitation. The video, the first in a series that will feature familiar faces from film and TV — Scarlett Johansson and George Clooney are involved — is intended to raise awareness about the global water crisis, a cause near and dear to Damon, who’s one of the cofounders of Water.org.
