An oil spill still threatens part of the world's largest mangrove forest in Bangladesh.
The oil spill covered nearly 40 miles of waterways. At low tide, oil marks are still clearly visible on the mangrove trees inside the Sundarban Forest.
Cargo vessels are forced to wait on Pashur River while the clean-up is under way.
The people who usually fish in the Sela River are now busy collecting the oil.
The spill has affected the people who have homes by the Sela River and make a living from the waterways.
The Forest Department has encouraged local people to help with clean-up efforts. Villagers have been scooping oil from the rivers using pots and pans.
It has become a source of income for many. Some of the oil is put into drums and sold to a state-owned oil company after it is collected.
An oil spill from a crashed tanker in Bangladesh's Sundarbans waterways is threatening a rare dolphin sanctuary and part of the world's largest mangrove forest. Much of the surrounding environment is now toxic.
The tanker, believed to be carrying 350,000 litres of oil, collided with another vessel on 9 December. It has now been brought to shore.
Many people continue to use water from the river for their daily household needs, despite the risks to their health.
The Sundarbans area contains part of the world's largest mangrove forest. But locals say mangroves by the river bank are going to die, as oil from the spillage has covered their roots.
