Matt Damon is taking a stand on the global water crisis - by not squatting.
In a YouTube video of a mock press conference, the Oscar-winning actor and philanthropist jokingly announced that he will refrain from going to the bathroom to raise awareness of the 780 million people worldwide who lack access to clean water and the 2.5 billion who are without 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," the "Promised Land" actor said. "More people have cellphones than toilets."
The three-minute video is sure to draw laughs, but Damon, co-founder of Water.org, which released the video earlier this week, is serious about the issue.
"Does anybody have any idea what invention has saved more lives than any other in the history of humankind?" the actor asked at the start of the faux press conference. "The toilet."
The video is part of a viral campaign intended to draw money and attention to the global water crisis through the website, StrikeWithMe.org.
According to Damon, for just $25, one person can get clean water for life.
