Buriganga, the main river flowing beside Dhaka city, capital of Bangladesh, is now one of the most polluted rivers in Bangladesh because of rampant dumping of industrial and human waste. 40-50 years ago, a cruise on the historic Buriganga River in the capital used to be a must for visiting dignitaries. It was once the main source of drinking water for Dhaka residents. These days visitors are confronted with foul smells and rotting fish caused by massive pollution. This stench is unbelievable. According to the Environment Department, up to 40,000 tons of tannery waste flows into the river daily, along with sewage from Dhaka, a city of more than 10 million. Illegal structures have sprung up along its banks, narrowing the river and adding to the dirt, whilst ferries spill oil into its waters. It is now a dying river and the situation will get worse unless steps are taken urgently to reverse the trend.
