Description : An aerial view of the Hazaribagh neighborhood, in Dhaka. The mega city is expanding fast horizontally as well as vertically. Most single family homes that used to house one family have now been replaced with tall apartment buildings with as many as 12 flats. Cost of real-estate have sky rocketed making it impossible for people to afford single family homes any longer. Hazaribagh neighborhood is also home to over 194 tanneries that operate here and freely dump untreated toxic wastes directly to the low-lying areas, river and natural canals. Bangladesh.
