The Indian town of Pushkar is located on the edge of the Thar desert and hosts the world's largest camel fair in the world every winter. It draws local camel traders as well as tourists, photographers and filmmakers from across the world. Underneath the attention Pushkar receives for a week are some of the town's poorest people who use the opportunity to address one of their most basic need. It is a challenge that some 2.5 billion people face everyday across the world.
