Slavery: A 21st Century Evil is an incredibly horrifying and enlightening series on modern day slavery by Al Jazeera. As the opening monologue claims, slavery did not end with the emancipation declaration but continues to this day in many guises. In seven episodes, Al Jazeera investigates Food Chain Slaves in America, Sex Slaves in Europe, Bonded Slaves in Pakistan, Child Slaves in Haiti, Charcoal Slaves in Brazil, Bridal Slaves in India, and Prison Slaves in India. I cannot post the episodes here as Al Jazeera has disabled embedding, but they are all freely available on Youtube. They truly are a must watch if you at all care about how the vulnerable around the world are treated, and where many of the products we use come from.
