Matt Damon has officially gone on strike from using the toilet -- and he wants his fans to do the same! The Promised Land actor, 42, hosted a faux press conference in a new viral video PSA that reveals his decision to boycott the toilet.

"Anybody have any idea what invention has saved more lives than any other in the history of humankind? The toilet," the co-founder tells reporters in the video campaign. "What's even more shocking is the catastrophic worldwide lack of clean water and sanitation. 780 million people -- that's twice the population of the United States -- lack access to clean water. 2.5 billion people lack access to a toilet or basic sanitation. I mean, more people have cellphones than have toilets."

To help support's cause, Damon declared, "In protest of this global tragedy and until this issue is resolved . . . I will not go to the bathroom."

Actress Kate Micucci, playing a reporter in the video, then asked, "Do you mean literally, like you won't go to the bathroom, but will go somewhere else like maybe a swimming pool?"

"You're the reporter, you do the math," he said, and added, "The toilet strike, it's important."

And Damon wants everyone to help. "Join me," he said. "Say no to toilets. Say yes to clean water for all."
