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

The Baitarani river system in Odisha has undergone significant decay in recent years due to a number of geographical factors. One major cause of this decay is the increasing levels of pollution in the river. Industrialization and urbanization have led to the release of various pollutants such as chemical waste, untreated sewage, and solid waste into the river, leading to the deterioration of its water quality. This has severely impacted the river's biodiversity, with many species of fish and other aquatic life dying off or becoming endangered.

Another cause of the decay of the Baitarani river system is the overuse of its water resources. The river is heavily relied upon for irrigation, drinking water, and other domestic and industrial purposes, leading to a depletion of its water levels. This has led to severe drought and water shortages in the region, affecting the lives and livelihoods of the local population.

Another factor contributing to the decay of the Baitarani river system is the lack of proper waste management practices in the region. With no proper infrastructure for the disposal of solid waste, garbage and other forms of waste are often dumped into the river, leading to further pollution and deterioration of its water quality.

Furthermore, the construction of dams and barrages on the river has also had an impact on its health. These structures have disrupted the natural flow of the river, leading to siltation and erosion of its banks. This has caused significant damage to the river's ecosystem, with many species of flora and fauna being affected.

Overall, the decay of the Baitarani river system in Odisha is a result of the combined effects of pollution, overuse of water resources, lack of proper waste management practices, and the construction of dams and barrages. These factors have led to the deterioration of the river's water quality, biodiversity, and ecosystem, severely impacting the lives and livelihoods of the local population.
