Refers to the process by which a body of water becomes overty enriched with nutrients, typically nitrogen and phosphorus. This excess of nutrients often comes from human activities such as agricultural runoff, sewage discharge, and the use of fertilizers. As a result, it stimulates the excessive growth of algae and other aquatic plants. The increased plant growth can lead to a series of ecological problems.
The algae and plants eventually die and decompose, and this decomposition process consumes oxygen, depleting oxygen levels in the water. Low oxygen levels can harm fish and other aquatic organisms, leading to a condition known as hypoxia. Eutrophication can disrupt the balance of ecosystems, negatively impacting water quality, biodiversity, and the overall health of aquatic environments.
