Human trafficking is a multi-billion dollar criminal industry that transports people illegally across borders for forced labor and sex trafficking. An estimated 800,000-900,000 people worldwide are internationally trafficked each year, the majority being women and children. Human traffickers exploit victims by concealing them in shipping containers for transport, subjecting them to inhumane conditions with risks of death from hypoxia, malnourishment or dehydration. Port security needs training to identify signs of human trafficking in shipping containers to help combat this criminal industry.
