The anti-poverty advocacy group ONE unveiled a new PSA titled "The F Word: Famine is the Real Obscenity" on Tuesday. In the minute-long clip, George Clooney, Bono, Jessica Alba, Rob Lowe, Joe Jonas, Colin Farrell and countless other stars bring attention to the devastating famine occurring in Somalia.

"Thirty thousand children have died in just three months," Clooney explains.

"There are things that can be done, and if we really believe the life of a child in East Africa is worth the same as the lives of our own children, we have to act," Bono says.
