In this June 29, 2015 photo, a makeshift squat toilet installed over a shallow pit serves families living in and around damaged buildings behind the ruins of the National Theater, in central Port-au-Prince, Haiti. Sanititation is a problem in camps and squatter settlements alike. Many people live without access to any toilet facilities, and water for drinking and washing must be bought in by the bucket.
