For the last three-four decades, the fisherman issues in and around the PARK BAY’ & the ‘GULF OF MANNAR ’ region have persisted and have affected the bilateral relations between Indian and Sri Lanka. Reasons for the issue: Indian fishermen from Tamil Nadu have largely exhausted their fisheries resources in India.s EEZ:   Because they mostly used an unsustainable fishing practice known as “Bottom Trawling”. In Bottom Trawling: Mechanized boats make use of deep trawler nets to scoop up anything in their path, the bottom of the sea. They end up catching huge quantities of fish (many of which are not even consumed) and they even cause serious environmental degradation. Impacts : Serial resources depletion: The practice is unsustainable, the practice does not provide enough time or replenishment. Causes damage to sea floors: and other many marine animals including coral reefs. In the long run, it can even disrupt the biogeochemical channels. Reducing carbon sequestration rates. Hen

DEFINITION OF WATER POLLUTION: The addition of certain substances to the water bodies such as organic, inorganic, biological, radiological heat degrades the quality of water so that it becomes unfit for use . SOURCES OF WATER POLLUTION: Point sources: All the pollutants that travel directly from source to water. They are easy to regulate. Diffuse or non-point source: These pollutants include community waste and industrial waste. They are difficult to regulate. Agricultural source: Excessive use of chemicals and fertilizers by farmers is also a major source of water pollution as it pollutes underground water resources. Thermal pollution: In thermal and nuclear power plants, water is used as a coolant and releases hot water to the original source, this sudden rise in temperature kills fishes and other aquatic animals. Underground water pollution: Contamination due to seepage from industrial and municipal waste and agricultural runoff. Marine pollution: Oceans are the ultimate sinks of na
