The challenge to make chocolate child labour free

There are over a quarter of a million children who work in the cocoa plantations of West Africa. It's hazardous work, which exposes children to highly toxic pesticides. This episode of the BBC World TV series 'Survivors Guide' goes to Cameroon, where the International Labour Organization has been working to eliminate child labour from cocoa production and help children return to school. Produced by Rockhopper TV in cooperation with the ILO.
