La Chureca, the city dump on the outskirts of Managua, Nicaragua, could be the setting for a dreary, futuristic movie. A city of scavengers, many of them orphans, they live in the filthy heaps of refuse at this municipal garbage dump. Clothed in rags, they rummage for food, scrounging out a meager existence by selling the small trinkets or recyclables they find, or sometimes selling their own bodies to survive.
