Where does eutrophication happen?

Eutrophication typically occurs in aquatic environments such as lakes, rivers, and coastal areas, where nutrient runoff from fertilizers, wastewater, and agricultural activities leads to an overabundance of nutrients, particularly nitrogen and phosphorus. This nutrient influx promotes excessive growth of algae and aquatic plants, resulting in algal blooms. As these organisms die and decompose, oxygen levels in the water can drop, causing harm to fish and other aquatic life. This process can significantly disrupt ecosystem balance and water quality.
