Sidiki Mayamba, left, puts on his shoes in the room he shares with his wife Ivette Mujombo Tshatela and their 2-year-old son Harold Muhiya Mwehu in Kolwezi on June 10, 2016. Mayamba is a “creuseur”, or digger who works in the cobalt and copper mines that surround Kolwezi. He says he works in harsh conditions to bring home $2-3/day. Mayamba and his family rent part of an unfinished home and have no electricity or running water. (Photo by Michael Robinson Chavez/The Washington Post)
