Algal Bloom

What are the impacts of cultural eutrophication on water quality?

Answer explanation

Cultural eutrophication leads to nutrient over-enrichment, causing algal blooms that deplete oxygen and block sunlight. This results in poor water quality, harming aquatic life and disrupting ecosystems.
