As cocoa prices decline on the global market, already-poor farmers are forced to accept whatever price theyï¿½re offered by buyers. These low prices make it difficult to cover production costs, including wages, and low wages lead to a child-labour force. Cocoa is grown in various parts of the world, including Asia and South America, but by far the largest producer is West Africa, where two countries ï¿½ Ghana and Cï¿½te dï¿½Ivoire ï¿½ account for 60 per cent of the worldï¿½s cocoa crop. Here, the majority of cocoa is grown on small family farms. Itï¿½s estimated that 1.8 million children work on these farms. Many of these kids have to work long hours in extreme heat, carry heavy tools and work with pesticides that are known to cause headaches, nausea, liver and kidney complications and cancer.
