Mostly on candy, and mostly on chocolate. where small Landholders grow more than three million metric tons of the fruit of the cacao tree. at least 10,000 of these kids are likely enslaved.

美國人過萬圣節(jié)已經花了將近70億美元，錢大多使用在糖果以及——巧克力上。 然而，即使是雪白的牛奶巧克力也有鮮為人知的黑暗面。如今，大多數(shù)巧克力產于西非。在西非，那片狹小的土地孕育了300萬多公噸的可可豆，要將可可豆變成巧克力則需要勞動力，而這些大量的勞動力正是童工。 據(jù)美國國務院調查，在象牙海岸和加納，有超過10萬個童工生產了全世界一半多的可可，更令人心寒的是，這些孩子中至少有一萬人可能淪為了奴隸。 2001年，包括好時、吉百利這樣的大公司在內的可可生產工廠，保證童工不會再出現(xiàn)在可可園里，但是這一承諾還遲遲沒有實現(xiàn)，目前的目標只能確保大約一半的農場不會再使用童工。 公平貿易認證的巧克力不僅有助于解決童工問題，還讓非洲農民在可可貿易中有利可圖。如若不然，試想，從非洲受奴役的童工手上拿走巧克力，送給美國的孩子，這本身就是一種骯臟的惡作劇，畢竟，沒人想在萬圣節(jié)成為奴隸。
