The holiest river of Hinduism. It rises in the Himalayas and flows a comparatively short 1,560 miles to the world's largest delta, on the Bay of Bengal. Among that delta's distributaries are the Hooghly (on whose banks Kolkata — formerly Calcutta — may be found) and the Padma (which enters Bangladesh). Approximately one in every twelve human beings lives in the Ganges Basin, a population density that is rapidly polluting the river; a significant source of that pollution is cremated remains.
