9Dhaka, Bangladesh

Dhaka, the capital of Bangladesh, is another city grappling with a high level of pollution. Rapid industrialization, particularly from the garment and textile sectors, has led to alarming levels of water pollution in the rivers surrounding the city. 

The Buriganga River, once a vital water source, is now severely polluted due to industrial waste and untreated sewage. The air quality is also poor, primarily due to the rising number of vehicles, brick kilns, and construction sites. The city’s inability to handle its waste effectively results in unsanitary living conditions for many residents.
