We all love chocolate , and most of us probably eat it every day , or at least several times a week.It is one of the most favourite kinds of food in the world , and many would say that they could not live without it.However , there are many facts about the world of chocolate that most people do not know. Have you ever wondered where your chocolate comes from? Most of it comes from the labor of children.It is said that in Africa alone , there are about 70 million children working on chocolate farms.They lead a very hard life , and many live only on bananas and corn paste ( 糨糊 ) . One child who was interviewed said that he was tricked into believing he would be earning money to help his family.But the truth is that he is treated like an animal.The child has never even had the chance to taste the chocolate he spends his life producing. The history of chocolate pretty much begins with the Mayans( ) . Ca( 可可 ) beans were so valuable to Mayans that they were used as money.It is said that ten beans could buy a rabbit , and one hundred beans were enough to buy a slave( ) . People would buy everything from food to tools with the beans.Generally , only the richer people drank chocolate regularly , because drinking your money is expensive.
