It is a city of marked contrasts: hawkers moving in and out of the Victorian arcades of South Mumbai; a river separating Dharavi’s household enterprises from the business district of Bandra Kurla Complex; beaches dotted with joggers and vendors; the international airport surrounded by Lego-like houses made of brick and tarpaulin, each with its own dish antenna anchored on the roof. Along its picturesque coastal setting by the Arabian Sea, heaps of garbage are deposited from the ocean every monsoon and strewn along the length of Marine Drive, a seaside promenade that forms part of the popular imagery of the city.
