Nutrient pollution, primarily from excess nitrogen and phosphorus, severely impacts aquatic environments by causing eutrophication. This process leads to excessive algal blooms, which deplete oxygen levels and result in dead zones where aquatic life cannot survive. Increased nutrient loads disrupt the food web, harming fish populations and biodiversity. Furthermore, harmful algal blooms can produce toxins that affect both aquatic organisms and human health. Addressing nutrient pollution is thus essential for maintaining healthy and resilient ecosystems.
