“There are many physical, chemical, and biological factors that combine to create dead zones, but nutrient pollution is the primary cause of those dead zones created by humans” (National Ocean Service). Nutrient pollution is when too many nutrients enter the water. Chemicals that are commonly found in nutrient pollution are phosphorus and nitrogen. The excess amount of nutrients in the water gives algae the ability to overpopulate the ecosystem. When algae dies it ends up sinking to the bottom of the ocean. When it decomposes, it releases oxygen which makes zones hypoxic. Dead zones can come from oil spills, wastewater, pollution in the rain, runoff from farmers, and illegal dumping of toxic
