Plastic pollution poses threat to ecosystem, biodiversity of Sundarbans

KHULNA, Jan 21 (BSS): Plastic pollution has been posing a serious threat to both the ecosystem and biodiversity of the Sundarbans, the largest mangrove forest in the world, for the last couple of decades. Prof Abdullah Harun Chowdhury of the Environmental Science Discipline at Khulna University said single-use plastics, used in Khulna and other areas near the Sundarbans, have made their way into the forest.

Besides, plastic bottles were seen scattered along the banks of Bhairab River near the forest frequently.

He explained plastic in coastal areas is entering the food chain through fish, affecting their reproductive process and growth. This plastic pollution also impacts other aquatic animals.

Single-use plastics have severely damaged the environment and biodiversity of the Sundarbans. Prof Chowdhury said the gravity of pollution caused by plastics is more than meets the eye.

Wild animals often end up eating these plastics."

Mangroves protect coastlines from erosion and extreme weather events, improve water quality by filtering pollutants and serve as nurseries for many marine creatures.

They can help fight climate change by sequestering millions of tons of carbon each year in their trees' leaves, trunks, roots and the soil.

The Sundarbans, located on the delta of the Ganges, Brahmaputra and Meghna rivers on the Bay of Bengal, also help buffer coastal communities in Bangladesh from the cyclones that frequently strike the country during its annual monsoon.

He said, "The Sundarbans and coastal areas are now covered in plastic. Single-use plastics are harmful to public health and the environment.

Quoting findings of much of the research he mentioned at least 17 species of fish and three kinds of species of shellfish in the three main rivers of the world's largest mangrove forest are infected with microplastics.

To address this issue, Prof Chowdhury emphasised the need for responsible tourism and collaboration with tour operators to promote sustainable practices.

He stressed the importance of adopting a circular economy that promotes plastic recycling and gradually eliminates its use altogether.

He also mentioned plans for a green growth strategy aimed at fostering environmentally friendly development.

"It's important to educate future generations to reduce plastic consumption," he said.

Nurul Karim, Divisional Forest Officer, Sundarban West Forest Division, Khulna, said they have informed all tour operators that single-use plastics are completely banned in the Sundarbans.
