Each year, the global sex slavery market generates $32 billion in profit, while the average age of American girls who are forced into prostitution is only thirteen. Today, some of the biggest celebrities in Hollywood are speaking out against this injustice, and they’re turning to YouTube to make sure the world hears them.

Through the DNA Foundation, an organization spearheaded by Ashton Kutcher and Demi Moore, a number of stars from Jessica Biel to Edward Norton, Justin Timberlake to Jason Mraz, are launching the “Real Men Don’t Buy Girls” video campaign. Watch the first episodes from the campaign here:

The campaign also makes use of YouTube annotations to help you join the movement and action against child sex slavery.
