 In this Aug. 28, 2018 photo, men who scavenge trash for valuables climb on a trash truck before it unloads at the Truitier landfill in the Cite Soleil slum of Port-au-Prince, Haiti. The landfill, home to about 500 families, is the center of deadly cholera outbreaks when flat lands flood during the rainy season and become a breeding ground for disease-carrying mosquitoes.
