The challenging lives of the world’s cocoa growers

More chocolate is sold in the U.S. than any other country in the world, the majority coming from Ivory Coast and Ghana. A new book, "Cocoa," examines the politics that go into its production with an analysis of power and inequality in the cocoa industry. Megan Thompson speaks with author Dr. Kristy Leissle, based in Accra, Ghana, who spent more than a decade researching chocolate.
