Unfortunately Mauritania isn't the last stronghold of slavery. Modern slavery exists in a number of places - including:

The Ivory Coast - cocoa farming. Child slaves are an exploited part of the labor force in cocoa production (yes, your chocolate's main ingredient, cocoa, may come from sources that employ forced labor). Info: http://en.wikipedia.org/wiki/Children_in_cocoa_production

The Unites States: there are an estimated 50,000 people trafficked into/out-of the US every year. 2.8 million children live in the streets, with over 30% exposed to the sex trade in some capacity. Source: http://www.gchope.org/human-slavery-statistics.html
