The magazine that World Vision puts out to sponsors had a really good article this month on how 3rd World countries are beginning to learn how to combat human trafficking. The article gives a really good first hand account of how this can be accomplished. Sadly, though, far more people get sucked into these horrendous schemes than get saved. This story, however, does have a happy ending. I link to it here because so many people, if they are even aware of this issue, think the situation is hopeless.
If nothing else, you can always pray.
