Nutrient pollution

Nutrient pollution occurs when excess nutrients, mainly nitrogen and phosphorus from sources like agriculture runoff, sewage, and detergents, enter water bodies. These nutrients fuel excessive algae growth, which can block sunlight and deplete oxygen in the water, harming aquatic life. The resulting algae blooms can produce harmful toxins and create dead zones where most marine life cannot survive. Nutrient pollution not only disrupts ecosystems but can also impact water quality, making water unsafe for drinking, recreation, and supporting fisheries. Managing nutrient inputs is essential to protect aquatic health and maintain balanced, thriving ecosystems.
