Not many people would know these very disturbing facts about Chocolate:
<ul>[*]70% of the worlds cocoa comes from the Ivory Coast in Africa.[*]More than 600,000 children who live in this region work on cocoa fields[*]284,000 children work in dangerous conditions[*]In Cote d’Ivoire on the Ivory coast 40-50% of children between 5 and 14 years of age work full time.[*]15,000 are captured, beaten, forced to work, underfed and not paid.[*]Many of these children are trafficked from other African countries like Mali.[*]Major chocolate companies know this but still buy from the criminals who run these plantations.[/list]</blockquote>
