RONDON DO PARA, BRAZIL - JUNE 08: A worker carries a bag of charcoal produced from illegally harvested Amazon rainforest wood up a ladder onto a truck on June 8, 2012 in Rondon do Para, Brazil. According to a recent Greenpeace study, illegal wood charcoal is primarily used in Brazil to power smelters producing pig iron, which is used to make steel for industries including U.S. auto manufacturing. Illegal charcoal camps were found to sometimes result in slave labor and the destruction of rainforest on protected indigenous lands. Between 2003-2011, 2,700 charcoal camp workers were liberated from conditions akin to slavery, according to Greenpeace. The workers in this photo said they were paid $40 per truckload of charcoal.
