Matt Damon envisions a day where everyone has access to clean water.
So when he was challenged by Ben Affleck and Jimmy Kimmel to do the ALS Ice Bucket Challenge that requires him to pour ice water over his head, he got the ice but did not want to waste clean water.
Instead, he took the water from his toilet to make another point and promote another cause that is important to him.

In his YouTube video, Matt says, "This is truly toilet water. I've been collecting it from various toilets around the house."
Although it was more than 24 hours later, Matt says he'll not only pay the fine and donate to ALS but wants to bring awareness to Water.org, a non-profit he co-founded to provide safe water and sanitation in the developing world.
He acknowledges the idea that what he is doing is disgusting and says his wife thinks so too, but then says, "Keep in mind that the water in our toilets in the West is actually cleaner than the water that most people in the developing world have access to."
According to Water.org, "An American taking a five-minute shower uses more water than the average person in a developing country slum uses for an entire day."
Bringing attention to two causes, Matt's video currently has over 150,000 views after just one day. He challenges his favorite actor George Clooney, musician Bono and quarterback Tom Brady to take the ALS challenge and bring just as much awareness.
