Think slavery is a relic of the past? Think again. The International Labour Organization estimates that nearly 21 million people today are enslaved. That means slavery is more prevalent today than ever.

Victims are often lured by false offers of a good job or education and kept enslaved by physical abuse, terror and debts they cannot repay. Even worse, over 4 million slaves are victims of forced sexual exploitation.

December 2 marks the International Day for the Abolition of Slavery. You can help combat modern slavery. Consider participating in campaigns like the ILO’s End Slavery Now and the U.N.’s Blue Heart Campaign. We all can spread public awareness of modern slavery and help free more of its victims.

If you suspect someone living near you is a victim, the State Department has information on how to identify and assist that person.
