A fire crackles along the banks of the Yamuna River: a cremation of a young mother, struck by a car while she was fetching water.
The stench of the river engulfs the sad assembly.
Before the hissing funeral pyre, floating down the river, white blocks of what looks like detergent appear like icebergs. It is 95 degrees in Delhi this night. This is chemical waste from factories that have sprung up across the city, manufacturing leather goods, dyes and other goods.
Downstream, the living reside along garbage-strewn banks.
