QUẢNG NINH — The Management Board of Hạ Long Bay in the northern province of Quảng Ninh is carrying out a campaign to collect styrofoam buoys left by illegal fish farms to avoid pollution in the UNESCO-recognised World Heritage Site.

The campaign, taking place from March 24-26, mobilises 20 vessels and 100 people who gather and bring the styrofoam buoys out of the area for treatment.

The styrofoam buoys, which have different sizes, were left by the illegal fish farms that were forced to be removed from the site. They have seriously affected the movements of vessels and the environment around the popular tourist site.

A large number of styrofoam buoys, along with other types of waste, have been cleared from the bay on May 24 and 25.

Located in the northeast of Việt Nam, the bay has attracted visitors from far and wide as it is home to over 1,600 limestone towers and islets covered in tropical trees. Most of the islands are uninhabited and unaffected by humans.

It was named one of the most beautiful places in the world to add to any traveller’s bucket list in 2022, according to Canadian travel publication The Travel. — VNS
