Human trafficking (or Trafficking in human beings) is a way to exploit people. People are sold, bought, traded much like slaves , and are even sold to couples who don't have children. It is estimated to be a $5 to $9 billion-a-year industry. Trafficking victims typically are recruited by using force or because they are deceived, or fraud is used, power is abused, or they are simply abducted. Threats, violence, and economic problems can often make a victim consent to exploitation.
