Aila prompts exodus

Sea levels rising between 3mm and 5mm a year; tidal surges will intensify say scientists

a steady stream of people can be seen making their way to the main jetty in Chotomollakhali island in the Sunderbans these days. On an average, about 200 of them leave for the mainland each day with their belongings and livestock.

The migration has increased threefold since Aila struck on May 25, said Gopal Mondal, primary school teacher on the island.
