A 2007 CNN Hero, Tina Frundt of Courtney's House works to save victims of child sex trafficking. She herself was a victim at the age of 14.
"The average age of forced prostitution in the U.S. is 11-14 years old. That is the target age that traffickers target to traffick children. So it's very important for young people to be aware of that," says Frundt.
