Surviving on a lifeless river in Bangladesh.

The Buriganga river in Bangladesh, once a lifeline for the capital Dhaka, is now so polluted that it emits a foul stench and appears pitch black, with hardly any fish to be found. The river's decline is due to widespread dumping of industrial and human waste, including untreated sewage and by-products of fabric dyeing. The country has about 220 small and large rivers, and a large chunk of its population depends on rivers for a living and transport.
