The ecosystem of rivers is kept in the category oc fresh or soft and flowing water. All civilizations in the world have originated in the fresh water river valleys. These are considered to be the cradle of human civilization. 

Therefore, rivers of fresh water in all civilizations have been recognized as mothers.

Central Ganga Area: Central Ganga Plain covers the areas of Eastern Uttar Pradesh and Bihar State. These are populated areas of human settlement. The main occupations of the residents are agriculture, animal husbandry, fishery and cottage industries based on them. In this area there are major tributaries of Ghaghra, Gandak, Kosi and Son, etc. Here, the flow of the Ganga diminishes and pollution is greatly increased by the mixing of mud, garbage, stool – urine, chemicals, etc. In these areas, the formation of the meander, alluvial soil plains, ox-bow lake, etc. also takes place.

Due to high pollution, the river’s water is also not suitable for bathing or drinking. Due to floods in the Kosi river in this area, there is a loss of excessive public life and property in Bihar. Fresh water dolphins, turtles, crocodiles, alligators, fish, etc. are the main creatures found in the rivers of this area. Vikramshila Dolphin Sanctuary in Bihar has been set up in 50 km area in Bhagalpur district. In this region, dolphin (souns) has been declared a national aquatic creature. It is also called the Tiger of fresh waters Dense forests are also found in this area. They are rich in wildlife.
