Papuan villagers gather in a river to pan for gold after sludge containing gold leaked from a pipeline of US mining giant Freeport-McMoran in Kwamki Lama, Indonesia. Striking Freeport workers said the leak was due to corrosion and were demanding at least an eight-fold increase in the current minimum wage of $1.50 an hour. (Tjahjono Eranius/AFP/Getty Images)
