Thread:Comments:Observing the 2012 Human Trafficking Awareness Day in the US, and wider world/Supply and Demand

Not ALL human trafficing is for sex, although it would seem that most is. If not for sex, what are the other reasons for the demand for this human supply? Illegal adoption? Power? Laziness? What can be done to overcome the DEMAND, besides public physical castration of those caught and convicted of sex trafficing?
