Sunitha Krishnan fights sex slavery

Since we're in the safe world, it's natural not to be interested in human right.
I heard number one engaged in sex industry in US is Koreans. How sad! But it's true. Aside from sex slavery, there are many kinds of human trafficking. As a teacher how do we approach this kinds of problem?
Haven't we avoided those topics in our classroom in the excuse the our teaching environment is not ready to teach? Including Koreans there are many teen victims around the world.
By the way who are the victims there?
Where does the money benefited from human trafficking go?
What would be the preventions of human trafficking?
Is it enough for our kids not to play violent games and to watch adult materials or is it enough to arrest gansters?
