An Indian Hindu family walks on the shallow banks of the Yamuna river, covered with chemical foam caused by industrial and domestic pollution, during Chhath Puja festival in New Delhi on Nov. 2, 2019. Despite the river being accorded the status of a living human entity by an Indian court, untreated sewage and industrial pollutants have turned it into one of the most polluted rivers in the world. The Yamuna is one of the major tributaries of the Ganges. (AP Photo/Altaf Qadri)
