A woman walks past a giant anti-human trafficking campaign poster displayed at an Immigration Bureau in Bangkok on August 19, 2009. Human trafficking currently ranks among the world's most thriving criminal activities with an estimated 2.5 million victims 'at any given time,' a United Nations report published in March 2009 said. Messages on the poster read: 'Don't be decevied' and 'You could be victim of human trafficking.' AFP PHOTO/PORNCHAI KITTIWONGSAKUL (Photo credit should read PORNCHAI KITTIWONGSAKUL/AFP/Getty Images)
