For example, the removal of detergents into water can have a negative impact on organisms in the waters. Fertilizing rice fields or fields with artificial fertilizers, then entering the waters will cause uncontrolled growth of aquatic plants called eutrophication or blooming. Some types of plants such as algae, water nails and water hyacinth will flourish and cover the surface of the water so that sunlight does not penetrate to the bottom of the water. As a result, plants that are below the surface cannot photosynthesize so that the oxygen content dissolved in water is reduced.
