Over 200,000 children work as slaves in West and Central Africa. Boys work on cotton and cocoa plantations while girls work as domestic servants and prostitutes. The article describes the story of Shyima, a 10-year-old girl who was bought by a wealthy couple and forced to work up to 20 hours a day with no breaks or days off, earning only $45 per month. Cocoa farmers are often paid so little that they resort to slave labor using children, who are not paid and can be beaten or killed if they do not work satisfactorily or try to escape. The author questions when and how child slavery began in Africa and why children would be chosen as slaves.
