In this photo taken Monday, Oct. 1, 2018, containers used for hazardous chemicals lie exposed and piled up at a junkyard run by the Chinese-led Dar Petroleum Operating Company in Gumry, near Paloch, in South Sudan. The oil industry in South Sudan has left a landscape pocked with hundreds of open waste pits with the water and soil contaminated with toxic chemicals and heavy metals, and accounts of "alarming" birth defects, miscarriages and other health problems, according to four environmental reports obtained by The Associated Press.
