Seen from above, a small boat travels the Buriganga River, thick and dark with pollution, in Dhaka, the capital city of Bangladesh. Though the water is filled with human and industrial waste, millions depend on it for their livelihood and transportation. “The Buriganga is economically very important to Dhaka,” Your Shot photographer Jakir Hossain Rana writes. “Launches and country boats provide a connection to other parts of Bangladesh.”
