Eutrophication is the process by which a body of water becomes enriched in dissolved nutrients, usually nitrogen and phosphorus, that stimulate the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen. It can occur naturally or be accelerated by human activities such as agriculture and development. When eutrophication is accelerated by human activities, it can negatively impact the balance of organisms in the body of water and potentially lead to algal blooms and fish kills due to low oxygen levels. Managing eutrophication involves reducing nutrient inputs from fertilizers and erosion.
