A pile of quarried lime in one of multiple informal markets located at Warwick Junction, Durban, South Africa. Lime is a versatile mineral, and its many uses include construction, agriculture, and sunscreen. The lime traders at Warwick, mostly women, rotate every few weeks, vacating the space for other traders as they return to the mines for more product. Because lime traders often come from afar, they are the only traders at Warwick permitted to sleep in the market. (Renny Simone)
