All of us have seen – and probably rolled their eyes at – a campaign for social good on Facebook. In the beginning, these campaigns were along the lines of Facebook statuses like, “Like this if you want a cure for cancer” or putting up a picture of a cartoon to draw awareness of child abuse, as if people were not already aware that child abuse existed. Now, though, as Facebook is maturing, non-profits are coming up with interesting ways to harness the power of the social network to actually do good things.

Case in point: UNICEF. This month is World Water Month, which ties in naturally with UNICEF’s pet program The Tap Project. In order to raise money for the program, users can join the project’s app. As the Huffington Post reports, donating $5 provides drinkable water for a child for 200 days.

Clean water may not be the most exciting cause, but it’s a valid one nonetheless. Waterborne illnesses kill 4,000 children under the age of five each day, and are the second leading cause of preventable deaths for children under the age of five.

So sign up before the month is over! You know you were just on Facebook anyway.
