Matt Damon has breaking news: he is on a toilet strike.

In a new parody video clip for the organization Water.org, Damon tells a room full of news reporters that he will refrain from going to the bathroom in protest of the 2.5 billion people who lack access to a toilet or basic sanitation.

"In protest of this global tragedy, until this issue is resolved, until everybody has access to clean water and sanitation, I will not go to the bathroom," Damon said in the video.

The actor also points out that 780 million people, or twice the population of the U.S., lack access to clean water.

The video opens with Damon asking a room full of reporters how they spent Toilet Day, a real event which raises awareness of the global toilet problem.

"Sorry, World Toilet Day? is that even a real thing?" one reporter shoots back.

"Yeah, of course it's a real thing," Damon responds, becoming agitated. "November 19---World Toilet Day. How'd you celebrate it?"

He looks out to a sea of blank stares, but continues undeterred.

"Anybody have any idea what invention has saved more lives than any other in the history of human kind?" Damon asks. The toilet--I'm not at all surprised you gasped."

"We didn't gasp," a reporter says.

Damon co-founded of Water.org with the nonprofit organization's current CEO Gary White, in 2009. Water.org has provided safe water and sanitation to hundreds of communities in Africa, South Asia, and Central America.

"Matt's strike announcement and the vlogger videos are designed to start an online conversation that can engage people across the digital landscape, and we hope people will share the video, and respond to it with their own thoughts," White said. "I've been working on the water crisis for over 25 years and the interest and excitement for our work against one of the world's most solvable problems has never been more real. We are confident we will solve this crisis in our lifetime."

Damon is also planning on doing more YouTube videos for the cause, with original cameos scheduled on the YouTube channels of ShayCarl, EpicLloyd, WheezyWaiter, LivePrudeGirls, Smosh, Stan Lee, Lisa Schwartz, and John Elerick.

The actor, who parodied his own passionate activism in an appearance as himself on the HBO show "Entourage," back in 2009, pleads with the reporters in the new clip to join his cause and not go to the bathroom.

"Guys, the toilet strike is important," he said. "Who's with me?"
