This nutrient pollution produces “dead zones” in aquatic ecosystems by way of a course of action referred to as eutrophication: algae feed to the nitrogen and phosphorus, resulting in algal blooms. When the excess algae die, the microorganisms that decompose the dead algae expend the water’s oxygen supply, suffocating fish along with other aquatic organisms.
