Surviving on Bangladesh's Toxic 'Dead' River

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. The river's ecological decline is due to the widespread dumping of industrial and human waste, including untreated sewage and chemical waste from nearby mills and factories. The booming garment industry is also a major contributor to the pollution. Despite regulations requiring industrial units to use effluent treatment plants, many flout the rules. The river is now biologically dead, with no fish or aquatic life during the dry season.
