CNN 's Freedom Project returned to Africa 's cocoa plantations to look for progress in fight against child labor . The project found that the number of children working on farms has dropped dramatically, but they are still being exploited by their parents and other adults who work with them. Cocoa farmers earn just a tiny fraction of the cost of the average chocolate bar . Over the same period , the value of cocoa within a chocolate bar has halved from 12 % to just 6 % , so although a farmer 's cocoa is essential to a chocolate bar , its value is a small part of the ultimate cost of production . Global demand for cocoa outstrips supply , offering hope that the industry may do more to help growers .
