Going undercover to meet slaves and slaveholders for his book Disposable People: New Slavery in the Global Economy, Kevin Bales exposed how modern slavery penetrates the global economy and flows into the things we buy. Disposable People was named by the Association of British Universities as one of “100 World-Changing Discoveries” and published in ten other languages. In 2001 he co-founded the NGO Free the Slaves, which has liberated thousands of slaves worldwide. After reading Bales’ book Ending Slavery, President Clinton told the plenary of the CGI: “It tells you that it is a problem we can solve and here’s how to do it.” Bales is the Professor of Contemporary Slavery at the University of Nottingham; and Lead Author of the WalkFree Global Slavery Index. The film based on his work Slavery: A Global Investigation (HBO/BBC) won a Peabody and two Emmys. Bales has advised the US, British, Irish, Norwegian, and Nepali governments as well as the European Parliament on trafficking and slavery policy. His newest book is, Blood and Earth: Modern Slavery, Ecocide, and the Secret to Saving the World . Check out his TED Talk.
