I want to know the answer to the following question:
How many child slaves were reported in cocoa, coffee and cotton farms?
All the background I'm provided with is that "In 2001, the US State Department estimated there were 15,000 child slaves cocoa, cotton and coffee farms in the Ivory Coast, and the Chocolate Manufacturers Association acknowledged that child slavery is used in the cocoa harvest.[not in citation given][better source needed]". Is that enough to answer the question?
