27 million people are currently used as slaves across the globe. These people work in fields and factories, as prostitutes and soldiers, and, at an average price of $90 per person, have become a $32 billion industry. Slavery is alive and well in the 21st century. Second only to the drug trade, human slavery is the largest illegal industry today, with trafficking networks spanning from the darkest corners of the developing world to the streets of most major Western cities. What is truly shocking is how prevalent slavery is today, and how dependent we are upon it.
