Matt Damonis so concerned about Mother Earth that he recently released a video where he claimed that he would stop toilet use until more people took the water crisis seriously. He's not that serious, but the video is part of his work with Water.org, an organization he cofounded that works to supply clean water to the nearly 1 billion people who lack access to it. "I think what resonates with me most is when you see people living without clean water and they're forced to scavenge for water and basically use up all of their time doing just that," he has said. "You realize that they're in such a crippling cycle of poverty; it's just a death spin that they can't possible get our of." Even though this is a serious matter, Damon approached the subject with some levity. Watch the video here!
