Nutrient pollution significantly impacts freshwater bodies by causing eutrophication, a process characterized by excessive nutrient enrichment, particularly nitrogen and phosphorus. This leads to disproportionate algal blooms, which deplete oxygen levels in the water and create dead zones, killing aquatic life and disrupting ecosystem balance. Algal blooms can also produce toxins harmful to marine and human health. Furthermore, nutrient pollution affects water quality, making it unsuitable for drinking, recreational activities, and fishing. Addressing nutrient pollution is essential for maintaining healthy freshwater ecosystems and ensuring safe water supplies.
