LA OROYA, PERU - FEBRUARY 12:  A pile of processed zinc  sits inside the Doe Run Metallurgic Complex on February 12, 2008 in La Oroya, Peru.  The smelting plant in La Oroya, Peru, which processes metals like gold and silver, emits toxic gases into the air that pollute the environment. Children and adults alike suffer from headaches, body aches, fatigue and respiratory problems.  The majority in La Oroya live in poverty and can’t afford to see doctors or buy medicine; sometimes their only option for getting healthy is to leave town.  The people of La Oroya, in large part, depend on the very plant that is poisoning them.  (Photo by David Rochkind/Getty Images)
