What environmental issue is eutrophication associated with?

Eutrophication is primarily associated with the excessive nutrient presence in water bodies, particularly nitrogen and phosphorus. This environmental process occurs when these nutrients, often from agricultural runoff, wastewater discharge, or pollution, accumulate in lakes, rivers, and coastal areas. The surplus nutrients stimulate an overgrowth of algae, leading to harmful algal blooms that can severely disrupt aquatic ecosystems. This can result in decreased oxygen levels in the water, known as hypoxia, which is detrimental to fish and other aquatic life.

The relationship between eutrophication and nutrient overload is crucial because it emphasizes the need for effective water quality management and pollution control to prevent these environmental disturbances. Understanding this connection is vital for implementing strategies to mitigate the impacts of eutrophication and protect water resources.
