In the Sundarbans, the world's largest mangrove forest, the number of trees and animals is fast decreasing, according to multiple reports. A few days ago, a cargo vessel carrying about 775 tonnes of coal sank in the Sundarbans' Pasur River. This may result in a reduced level of pH in the nearby water and could severely harm aquatic creatures.

What's more, the construction of a coal-based power plant around the Sundarbans is well underway, defying public outcries and environmental concerns. I would urge the authorities concerned to take measures to maintain the ecological balance of the Sundarbans.
