Women collecting prawn seeds from the saline river of Sundarban delta. Poverty prevails among the villagers that about 60,000 families go into chest-high waters of the rivers of Sundarbans regularly in search of prawn seeds (Bagda), where they often fall prey to shark bites and catch skin diseases. Life in the Sundarbans, the largest delta in the world, is all about the struggle for survival, be it for food, shelter or for sheer escape from man-eaters. Gosaba, Sundarban, West Bengal, India.
