Bangladesh on 13 December 2014 launched an intensified manual campaign to clean up Sunderbans oil spill.
The forest department had engaged nearly 100 boats to collect the furnace oil spilled from the tanker which sank in the Shela river in the Sundarbans after being hit by a cargo vessel.
The seepage spread in the Shela and the Pashur rivers and over 20 canals which crisscross the Sundarbans in the past four days while officials found four out of six chambers of the tanker carrying 358000 litres oil damaged.
Officials said oil spill from the sunken tanker affected seven young saltwater crocodiles at Karamjal Wildlife Reproduction Centre and they were concerned about the fate of dolphins in the region it is their natural abode.
The authorities have filed a lawsuit against the owners of both ships. Bangladesh is yet to seek any overseas assistance to remove the oil but a London-based team officered its assistance for the clean-up.
The Sundarbans is the world largest mangrove forest, which covers 26000 square km in India and Bangladesh. It is also the habitat of famous Royal Bengal Tigers.
