In this photo taken Thursday, Nov. 12, 2015, Agnes Njoki, 17, takes a break with her daughter, Shantel Akinyi, 2, who accompanies her as she works scavenging for plastic at the garbage dump in the Dandora slum of Nairobi, Kenya. Men, women and children traipse through the murky sludge that weaves through mountains of garbage in Nairobi's notorious Dandora dump, hunting for anything that can be recycled to earn themselves enough for their daily bread - some of the poorest of Kenya's poor and those likely to be on Pope Francis' mind when he makes his first trip to Africa this week and brings his message of environmental stewardship and care for society's most marginal.
