Ever since Oprah heard about the genocide happening in Sudan and Uganda's young nightwalkers, she says she's had trouble sleeping at night.

"There is a holocaust going on right now in Africa," Oprah says. "Everybody who hears it today, can no longer say, 'I didn't know that was going on.' ... Maybe you feel like you have no real power to change anything, but the truth is, you are the only hope that all of these people have."

Oprah hopes that viewers will "rise up against the madness" and help stop the atrocities happening in Africa. "If we don't listen and do something now, we're all going to have blood on our hands ... If this was happening to your child, wouldn't you want the world to help?" she asks.

To lend a helping hand support, Oprah urges you to support organizations working in Africa.
