Dolphins

A school of gangetic dolphins have returned to the rivers Turag and Buriganga with the flow of fresh floodwater from the upstream. several dolphins were sighted recently near Shoalmachi in the river Turag and at Jhaochor, a kilometer downstream in the river Buriganga, much to the delight of environmentalists and local boatmen. But the delight is short-lived as the fresh water flow in all the rivers aroud the capital city will soon start to recede and dumping of millions of tonnes of toxic waste into the river water will make it impossible for any aquatic life to survive.
If the escape route towards the freshwater of the rivers Daleshwarei and Meghna is cut off,these aquatic mammals, representing a healthy atmosphere,will face certain death.
