Everyone loves chocolate. But for thousands of people, chocolate is the reason for their enslavement.

The chocolate bar you snack on likely starts at a plant in a West African cocoa plantation, and often the people who harvest it are children. Many are slaves to a system that produces something almost all of us consume and enjoy.

The CNN Freedom Project sent correspondent David McKenzie into the heart of the Ivory Coast – the world’s largest cocoa producer – to investigate what’s happening to children working in the fields.

His work has resulted in a shocking, eye-opening documentary showing that despite all the promises the global chocolate industry made a decade ago, much of the trade remains unchanged. There are still child slaves harvesting cocoa, even though some have never even tasted chocolate and some don’t even know what the word “chocolate” means.

Slavery still exists in our modern world. It is easy for most people in developed countries to live oblivious lives without ever hearing of these atrocities going on across the world. We all know that slavery is not okay; it is the fundamental denial of ones humanity. At the very least, we can be educated consumers that do not fuel these inhumane practices.
