Describe geographical cause of decay of Baitarani river system in the recent past.

There are several geographical causes that have contributed to the decay of river systems in India in recent years. Some of these include:

Urbanization: The rapid growth of cities and urban areas has led to the encroachment of rivers and their floodplains, leading to a reduction in their natural flow and an increase in pollution levels.

Deforestation: The cutting down of forests has disrupted the natural water cycle and led to the drying up of rivers, especially in areas with low rainfall.

Climate change: The increase in global temperatures has led to more extreme weather events such as droughts and floods, which have had a negative impact on river systems.

Overuse of water resources: The increasing demand for water has led to overuse of rivers, leading to their depletion and degradation.

Pollution: Industrial and domestic waste has led to the contamination of rivers, making them unfit for use.

Dam construction: The construction of dams and reservoirs has disrupted the natural flow of rivers and led to the loss of wetlands and other habitats.
