How your chocolate may be tainted: this may try the virtue of those of us who try to use our purchasing power to leverage social good. 43% of the world’s cocoa beans come from the Ivory Coast, where its cultivation and harvesting is achieved with adolescent slave labor. Americans spend $13 billion a year on chocolate; adolescent laborers in the Ivory Coast harvesting the fruit of the cacao tree have never heard of chocolate. Representatives of the industry say the harvests are pooled, so it’s impossible to discriminate products produced by dint of slave labor with those for which a decent living wage was paid.
