In "Chocolate's Child Slaves," CNN's David McKenzie travels into the heart of the Ivory Coast to investigate what's happening to children working in the cocoa fields. (Premieres Friday January 20, 8 p.m. GMT, 9 CET on CNN International.)

It's easy to say that human trafficking is a violation against basic human rights and that it should be abolished. And we often assume that modern-day slavery only takes place in countries far away.

But chances are, you have purchased, eaten, or have worn something tainted by slavery sometime in your life. Curious about what some of those connections might be? Calculate what some groups call your "slavery footprint"  or check out Anti-Slavery International's interactive map  of products, which includes something many of us love: chocolate.

So, how can you prepare yourself as a consumer before you bite into that chocolate bar or sip some hot cocoa? Here are a few ways.

Organizations like the 10 Campaign offer some ideas for taking action, such as signing an online petition against trafficked-linked chocolate, sending a 10th birthday card to the Cocoa Protocol or writing a letter to you local member of Parliament, senator, representative or other government official.
