Exploring the concept of eutrophication Environmental science essay
Eutrophication Definition. Eutrophication is the condition of a gradual increase in the concentration of phosphorus, nitrogen and other plant nutrients in a body of water, resulting in an excess of plants and algae. Eutrophication is one of the leading causes of ecosystem degradation in lakes. Its intensification over the past decades has led stakeholders to seek solutions for water management and restoration, including those based on modeling approaches. This article presents an overview of lake eutrophication modeling, where increasing global declines of submerged aquatic plants in lakes are commonly attributed to lake eutrophication, while other factors, such as water levels, are rarely considered. This study focused on the sudden extinction of the submerged plants in Caohai Lake, Guizhou, and used long-term data and water level manipulation over the entire lake. Vertical farming has emerged in urban areas as an approach to provide more resilient food production. However, a significant part of material needs comes from outside their urban environment. Since urban environments produce a large portion of residual and waste streams, there is extensive potential to use this material. Human-induced eutrophication degrades freshwater systems worldwide by reducing water quality and altering the structure and function of ecosystems. We compared current total nitrogen TN and phosphorus TP concentrations for the U.S. Environmental Protection Agency nutrient ecoregions to estimated reference conditions. For all nutrients, land-based management has reduced nutrient discharges, but many coastal water bodies are still degraded. The 'bioextraction' of nutrients by oysters and how oyster aquaculture could complement existing management measures in urban estuaries was investigated in Long Island Sound, Connecticut. Eutrophication status, nutrient removal. Eutrophication is one of the most common causes of water quality deterioration in inland and marine waters. The best known manifestations are the blooms of toxic cyanobacteria in lakes and waterways and the proliferation of green macroalgae in coastal areas. The term eutrophication is used by both the scientific community and environmental sciences, an interdisciplinary academic field that uses ecology, geology, meteorology, biology, chemistry, engineering and physics to study environmental problems and the human impact on the environment. Environmental science is a quantitative discipline with both applied and theoretical aspects. Eutrophication is the phenomenon characterized by an abundance of nutrients in a body of water, causing excessive growth of simple plant life. This process is clearly visible by the uncontrolled proliferation or bloom of algae and plankton. Eutrophication poses a serious threat to the environment as it often leads to greenhouse gas emissions, which are closely linked to climate change and severe ecological instability and have attracted worldwide attention. The estimation of critical aquatic drivers of greenhouse gas fluxes into lakes is an important step in controlling and reducing greenhouse gas emissions. The importance of aquatic factors for greenhouse gas emissions was estimated. Lake eutrophication, as one of the most challenging global environmental problems for more than half a century, is in trend.
