Eutrophication

Eutrophication is the process by which water bodies receive excess nutrients, primarily phosphorus and nitrogen, leading to increased growth of algae and aquatic plants. This phenomenon can result in harmful algal blooms, decreased oxygen levels, and negative impacts on fish and other aquatic organisms, often resulting in dead zones where life cannot sustain. Eutrophication is mainly driven by agricultural runoff, sewage discharge, and the use of fertilizers.
