In the area under Sunderban delta on the western banks of the Matla River, most inhabitants of the delta are fishermen who are facing challenges as the ocean swallows up land in the world's largest mangrove forest. Humans and tigers are being squeezed into an ever-shrinking space in the Indian Sundarbans with deadly consequences. The sea level has risen by an average of 3 - 5 centimeters a year over the past two decades in the Sundarbans leading to one of the fastest rates of coastal erosion in the world.
