Residents and workers at La Chureca in Managua, Nicaragua, pick through the mountains of trash looking for recyclables to exchange for cash. In 1972, Managua was devastated by an earthquake that rendered many of the city's poorer barrio's uninhabitable. That year many displaced people moved into the landfill to pick through the rubble. Since then, the landfills population swelled to 2,200 people, an estimated half of which are children.
