Rea Inu Bake, from the Indian tribe Hunikui, takes part in a protest against slave labor outside the Chamber of Deputies in Brasilia, Brazil, May 8, 2012. Brazil's lower house is expected to vote on a constitutional amendment that would punish landholders found to be using slave labor. The bill would allow the government to confiscate all property of those found to be using slave labor. Eraldo Peres/AP Photo
