Dye-coloured water is discharged directly into the Buriganga river in Dhaka, Bangladesh, March 6, 2023. The Buriganga, or the “Old Ganges”, is so polluted that its water appears pitch black, except during the monsoon months, and emits a foul stench through the year. Bangladesh is the world's second-biggest garment exporter after China but citizens and environment activists say the booming industry is also a major contributor to the ecological decline of the river. Untreated sewage, by-products of fabric dyeing and other chemical waste from nearby mills and factories flow in daily. (Photo by Mohammad Ponir Hossain/Reuters)
