Eutrophication causes practical problems in water quality, aesthetics, and recreation These are usually reversible if nutrient loading is reduced Eutrophication also causes fundamental ecological changes Such ecological changes may or may not be reversible Eutrophication is also associated with major changes in aquatic community structure. Cultural appropriation occurs when a person from one cultural adopts the fashion, iconography, trends, or styles from another culture. While also absorbing all the oxygen from the water, creating dead zones. As per Wikipedia, “Eutrophication or more precisely hypertrophication, is the ecosystem’s response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.One example is the “bloom” or great increase of phytoplankton in a water body as a response to increased levels of nutrients.
