MABONENG, SOUTH AFRICA - MARCH 21: Homeless people cook food under a bridge in Maboneng district on March 21, 2016 in downtown Johannesburg, South Africa.  A former derelict industrial area, and a no-go area after dark, it is now a vibrant area with artists, businesses, galleries and tourists. A racially mixed cultural hub with markets on the weekend. Maboneng is the idea of young entrepreneur Jonathan Liebmann, and he owns and controls most of the buildings in the area. (Photo by Per-Anders Pettersson/Getty Images)
