Smoke rises from chimneys of leather tanneries in Kanpur, an industrial city on the banks of the river Ganges, India, Tuesday, June 23, 2020. Kanpur city produces an estimated 450 million liters of municipal sewage and industrial effluent daily, much of which flowed directly into the Ganges until recently. Today that number is lower, though it's not clear by how much, after a Ganges cleanup project closed some drains and diverted industrial pollution to treatment plants. (AP Photo/Altaf Qadri)
