An oil tanker carrying 358,000 liters (almost 100,000 gallons!)

An oil tanker carrying 358,000 liters (almost 100,000 gallons) of furnace oil sank in the Shela river on December 7, spilling oil over more than 60 kilometers (about 37 miles) of the Sundarbans. Located on in southwest Bangladesh, the Sundarbans is the largest single block of tidal mangrove forest in the world, covering approximately 10,000 square kilometers (3,900 square miles), of which 60 percent is in Bangladesh. The Sundarbans, a UNESCO World Heritage Site, is also one of the largest reserves for the Bengal tiger, and provides sanctuary to many other species.
