cultural eutrophication: causes

Cultural eutrophication causes major changes in the water with the addition of excess amount of nutrients; mainly phosphate and nitrates. being carried out, no oxygen is being produced that may help the fishes of the unfortunate demise. reduces the concentration of phosphate ion in the water. Cultural eutrophication currently affects millions of lakes and waterways throughout the world [4]. life by oxygenating it again thereby The nutrients accumulate in high concentrations plaguing the water bodies with algal blooms and cyanobacteria. Various structural and functional changes accompany both eutrophication and its reversal, oligotrophication. A good scenario of how human activities affect the ecology of water bodies is when humans dump sewage into water bodies. Eutrophication increases the growth of algae and minute plants as well as photosynthetic bacteria. reduce their numbers within the water. Causes of cultural eutrophication. What is more, the dense growth of algal blooms and other plants can block water supply systems limiting the availability of piped water. “Cultural eutrophication of lakes quickly causes algae and macrophytes to cover a bay with scum, form hairy filaments to enslime shorelines, and clog an entire … Cultural eutrophication or nutrient over-enrichment, especially of nitrogen and phosphorus, has degraded many coastal waters and has been invoked as a major cause of seagrass disappearance worldwide (e.g. Humans prefer clear water as opposed to nutrient-rich water. As more and more organic matter accumulates, the demand for oxygen from the Soon these species also This acceleration of nutrient inputs to surface waters is termed cultural eutrophication. water increases until there is no more dissolved oxygen to support the algae. Fertilizers. As the algae increases and dies, the aerobic decomposers also increase resulting in a higher demand for oxygen in the water body. Cultural eutrophication refers to situations where the nutrients added to the water body originate mainly from human sources, such as agricultural drainage or sewage. eutrophication. A common characteristic of eutrophication is the explosive growth of phytoplankton and other plants. Effects of cultural eutrophication. Any pollutants that get phosphorus and nitrogen into the water. Rivers, Lakes. This Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. Their presence in water bodies declines the availability of clean drinking water. Causes. When trees are cut, soil erosion occurs, which carries the sediment and other nutrients into water bodies creating a suitable environment for the explosive growth of algae blooms. Eutrophication manifests itself in an increase in algal biomass and deoxygenation of the water column, itself caused by heterotrophic mineralization of the organic matter produced. Organic waste. Other technologies that convert plant growth present in water bodies into energy have also been advanced. this, serious actions need to be taken to prevent further damage from this This led to the foundation of EnvironmentBuddy! I have lived on the countryside for over a decade of my life where I realized how human activities impacted the environment. Overgrazing Deforestation Agricultural techniques Water management…, Cigarette smoking causes natural contamination by discharging lethal air pollutants into the air. Cultural Eutrophication: This process is generally speeded up by human activi­ties; which are responsible for the addition of 80% nitrogen and 75% phosphorus to lakes and streams. carelessly cause environmental damage due to excessive use of fertilizers Cultural eutrophication has had dramatic consequences on freshwater resources, fisheries, and recreational bodies of water and is one of the leading… When humans cut trees, they increase the likeliness of eutrophication. Cultural denotes human involvement, and eutrophication means truly nourished, from the Greek word eutrophic. The toxic compounds can also go up the food chain through bio-accumulation and bio-magnification, causing other health complications like cancers. (And 6 Ways to Reuse Cartons), Are Paper Napkins Recyclable? becomes available to the water body of an ecosystem which allows for limitless Ecosystem Importance of Keystone Species 17 Examples of Keystone…. If industries cut back on their pollution and municipalities continue to pollute water systems, the gains will be very few. substances in the water. Furthermore, all essential elements of compost manure are broken down and synthesized by plants avoiding the eutrophication cycle. Eutrophication poses a problem not only to ecosystems, but to humans as well.Reducing eutrophication should be a key concern when considering future policy, and a sustainable solution for everyone, including farmers and ranchers, seems feasible. It is also the responsibility of the once again at home. Required fields are marked *, What are Hurricanes? Usually this occurs as a result of the introduction of a range of nutrients through fertilizers, chemicals, or soaps and detergents [5]. Later during my stint in medical school, I realized that many of our health concerns originate from neglecting our environmental responsibilities and this was just not sustainable in the long run. This generally describes the concept of cultural eutrophication. Top Environmental Issues We Are Facing Right Now. Eutrophication is most often the result of human activity. The use of fertilizers is the leading cause of eutrophication. growth of photosynthetic organisms such as algae. The European Union defines cultural eutrophication as The enrichment of water by nutrients, especially compounds of nitrogen and phosphorus, causing an accelerated growth of algae and higher forms of plant life to produce an undesirable disturbance to the water balance of organisms present in the water and to the quality of the water concerned, (European Commission, 1991). Natural eutrophication is the gradual buildup of nutrients, organic material, and sediments that takes place over centuries in many lake basins. The explosive growth of the algae and plants can lead to the development of extensive and dense mats of floating plants that make it difficult to set fishing nets in the water. photosynthetic organisms, but the species which depend on them for oxygen. Eutrophication is a serious environmental problem which Controlling nutrient sources can greatly reduce eutrophication, and hence, governments and municipalities across the world should develop stringent measures to discourage on-point pollution. 1998). turn reduces the amount of species in the ecosystem. systems available so they may work more efficiently in reducing the unwanted Agricultural practices and the use of fertilizers on lawns, golf courses, and other fields contribute to nutrient accumulation. the water further depleting the oxygen concentration. Trees play an important role in holding the soil together. Dead zones. There are three main sources of anthropogenic nutrient input: erosion and leaching from fertilized agricultural areas, and sewage from cities and industrial waste water. Although this is a slow process, it may be increased with the addition of human pollution which is called “Cultural Eutrophication “. This is due to the numerous toxins, The bacteria generate a red tide that releases very powerful toxins with high poison levels into the water. While eutrophication does pose problems, humans should be aware that natural runoff (which causes algal blooms in the wild) is common in … An increase in biological productivity and ecosystem succession caused by human activities. poison the livestock which graze around lake or waterways resulting in their My love for nature is not newfound. process. The cultural process is primarily associated with phosphorus common in fertilizers and treated sewage. Agricultural fertilizers are one of the main human causes of eutrophication. production of algae and aquatic plants resulting in a decrease in the number of Even if we are assured that the water coming from the Once the nutrients get into lakes, oceans, rivers, and other water bodies; algae, and plankton, among other aquatic plant life become well-fed resulting in an increase of their photosynthesis activity. the detergents. reducing or very well reversing the effects of eutrophication. Even treated water should not be discharged back into rivers or lakes as it can also cause an accumulation of excess nutrients into the water bodies. When water can no longer hold oxygen, the condition encourages the growth of bacteria that produces toxins that are fatal to marine mammals and birds. However, for this solution to work, industries, and municipalities, as well as individuals, should work together in reducing their pollution levels. A continuous increase in nutrient concentration in a lake decreases the ability of self-purification of the ecosystem and can even lead to the premature death of a body of water. Similarly, naturally productive lakes can be fertilized further by human-derived point and nonpoint nutrient sources. Lake Mendota and Lake Washington have undergone rapid eutrophication due to man’s activities is possible. The explosive growth of plants increases the demand for oxygen resulting in a reduced availability of dissolved oxygen for respiration by other aquatic plants and animals in the water. https://www.britannica.com/science/cultural-eutrophication, https://www.nature.com/scitable/knowledge/library/eutrophication-causes-consequences-and-controls-in-aquatic-102364466/, https://www.encyclopedia.com/environment/encyclopedias-almanacs-transcripts-and-maps/cultural-eutrophication, Rinkesh In fact, the idea of using nutrient-rich water by some people sounds insane. Detergents which contain high amount of phosphates should These structural changes are based on three major causes of eutrophication which include: Cultural eutrophication is affecting millions of lakes, rivers, waterways and other various water bodies throughout the world. After such organisms die, bacterial degradation of their biomass results in oxygen consumption, thereby creating the state of hypoxia. Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem.
