Water, which has been coloured by textile dye and will eventually flow through the Labandha, Turag and Buriganga rivers, is released near a paddy field in the Mawna Union area, north of Gazipur, Bangladesh on March 2, 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)
