Dharavi is in Mumbai, India. The second-largest slum in the continent of Asia, and the third-largest in the world, it is home to over a million inhabitants in the confirms of just 2.1 sq km.  Here, people live and work in very confined spaces - kids attend school, and they can even go to a cinema cafefully set up under large tarpaulins. This photograph taken on a four-hour walking tour, shows workers who pull apart keyboards, car parts, and toys to salvage, (amoungst other materials), plastics that are broken down into small chips - washed, and bagged up ready for manufacturing reuse.  The organisation in this place was truly fascinating.
