fish species and also a decrease in the quantity and quality of water. Cultural Eutrophication It’s a sort of eutrophication that is caused by human activities. The eutrophication in water causes many complexities not only for aquatic animals but also for the animals on land. Dead animals and plant materials are also decomposed by aerobic and anaerobic decomposers into simple forms that be easily recycled into the natural cycles. 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. Waste-water being discharged into water bodies, e.g. Over the last few years, tech developers and scientists have been working towards creating technologies that can help reduce pollution and even reverse the damages already caused. eutrophication. Types, Examples, Importance, What are the Longest Living Animals? natural ecosystem in which it is occurs. My love for nature is not newfound. 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. Cultural eutrophication causes major changes in the water with the addition of excess amount of nutrients; mainly phosphate and nitrates. The cultural process is primarily associated with phosphorus common in fertilizers and treated sewage. For example, eutrophication is highly associated with the poisoning of shellfish. Eutrophication is most often the result of human activity. 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. of aluminum, iron or calcium carbonate which form compounds of phosphates which The concept of cultural eutrophication is particularly brought about by a human understanding that clear water with minimal visible organisms is better than organic-rich water. be purified by water treatment plants. Organic waste. Causes of Eutrophication and Algal bloom | UPSC – IAS. Although this is a slow process, it may be increased with the addition of human pollution which is called “Cultural Eutrophication “. eutrophication and how the populations are increasing the chances of once again at home. Overgrazing Deforestation Agricultural techniques Water management…, Cigarette smoking causes natural contamination by discharging lethal air pollutants into the air. Governments should create laws and policies against non-point pollution. Causes of eutrophication 1.Concentrated animal feeding operations. Effects of cultural eutrophication. Ways to Protect and Conserve Biodiversity. Governments are, therefore, called upon to as well invest in supporting and encouraging new innovations that deal with environmental challenges. Agricultural fertilizers are one of the main human causes of eutrophication. The modern method of rearing fish, shellfish, and growing aquatic plants without soil is also becoming a big contributor to cultural eutrophication. Furthermore, all essential elements of compost manure are broken down and synthesized by plants avoiding the eutrophication cycle. reducing or very well reversing the effects of eutrophication. being carried out, no oxygen is being produced that may help the fishes of the Recent coastal surveys by the United States and the European Union found that 78% of U.S coastal waters and 65% of Europes Atlantic coastal waters exhibit symptoms of eutrophication. 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. Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem. Environmental issues are problems that have occurred as a result of human actions on…, [Updated: 7 August 2020] Navigation: What are Keystone Species? 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. This not only leads to the death of the - "The Globalization of Cultural Eutrophication in the Coastal Ocean: Causes and … The toxins can be fatal even at very low concentrations. Explain to them the causes and effects of eutrophication and Shellfish accumulate poison in their muscles resulting in human poisoning. Various structural and functional changes accompany both eutrophication and its reversal, oligotrophication. Mostly, eutrophication leads to easily detectable algal blooms which turn the water green in color as there are numerous amount of algae situated on the surface of the water. The process is characterized by excessive plant and algal growth in the water bodies. Under certain conditions of darkness and warm temperatures these blooms may die, decompose and produce offensive sewage-like odor. The most noticeable problem with eutrophication is the deterioration of water quality. Compost manure does not contain high elements of nitrates and phosphates that cause eutrophication. “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 … Besides, the algal blooms are highly toxic. Increased photosynthesis activity causes a dense growth of algal blooms and other plant species. Eutrophication is predominantly caused by human action. This is where I tell you about the Process of Cultural Eutrophication. Effects of Eutrophication: Eutrophication derives from the Greek word eutrophos, meaning nourished or enriched. Causes of Eutrophication Natural run-off of nutrients from the soil and the weathering of rocks. Hurricanes, known by different names around the world from typhoons to cyclones, are potent forces…, Navigation: Definition of Desertification Desertification Process What are the causes of Desertification? Abundant plant growth produces an undesirable disturbance to the balance of organisms and the quality of water. Minimizing non-point pollution works by lessening the number of nutrients that enter aquatic systems. In fact, the idea of using nutrient-rich water by some people sounds insane. Naturally, all bodies of water are being subjected to eutrophication. (And Can You Compost Them), Eutrophication is a major environmental concern. The cigarette butts additionally litter…, The environment protection agency(EPA) is a US based agency that acts as a fence between human activities and…, What are Environmental Issues? Dumping untreated sewage into a water body, for example, results in the fertilization of the algae, increasing their growth. Top Environmental Issues We Are Facing Right Now. This Ultrasonic irradiation, as an example, is one such technology that has tremendously helped in controlling eutrophication by causing cavitations that produce free radicals that destroy algae cells. unwanted organic compounds and bad undesirable odor. Natural eutrophication is the gradual buildup of nutrients, organic material, and sediments that takes place over centuries in many lake basins. This generally describes the concept of cultural eutrophication. Required fields are marked *, What are Hurricanes? FIGURE 2 | Global distribution of eutrophic coastal marine ecosystems (adapted from Breitburg et al., 2018). causes a significant reduction in the quantity and quality of fish available. Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. 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. Lake Mendota and Lake Washington have undergone rapid eutrophication due to man’s activities is possible. EPA points out that non-point pollution causes the biggest challenge in eutrophication control. Even if we are assured that the water coming from the Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The excessive growth results in a reduced presence of oxygen in the water thus triggering the eutrophication process. In cultural eutrophication, however, humans inject large amounts of artificial matter into the water’s ecological system thus overwhelming the natural cycle thereby resulting in the water bodies changing from oligotrophic to eutrophic. In a young lake the water is cold and clear, supporting little life. Cultural eutrophication causes excessive algal bloom in water bodies, with consequent algal overload. poison the livestock which graze around lake or waterways resulting in their Ecosystem Importance of Keystone Species 17 Examples of Keystone…. The use of fertilizers, especially nitrate and phosphate fertilizers on farms, lawns, and golf courses, result in the accumulation of phosphate and nitrate in the nearby water body sources. 1998). Farmers should be widely informed about how the use of reduces the concentration of phosphate ion in the water. water-treatment plants is clean drinking water, it doesn’t hurt to filter it Eutrophication most commonly arises from the oversupply of nutrients, most commonly as nitrogen or phosphorus, which leads to overgrowth of plants and algae in aquatic ecosystems. 1. If, for instance, a water source is affected, those dependent on nutrient-rich water would be unable to use the water until the quality improves. 13437 shares Improvements must be carried out in the water treatment A number of water filtration systems could help you out in turn reduces the amount of species in the ecosystem. Eutrophication is a major environmental concern for rivers, coastal water, lakes, tributaries, and estuaries. Industrial agriculture, with its reliance on phosphate-rich fertilizers, is the primary source of excess phosphorus responsible for degrading lakes (Carpenter 2008). They are responsible for the addition of 80% nitrogen and 75% phosphorus to lakes and streams. A good scenario of how human activities affect the ecology of water bodies is when humans dump sewage into water bodies. thrive and grow sufficiently to degrade the algae. Cultural eutrophication causes major changes in the water with the addition of excess amount of nutrients; mainly phosphate and nitrates. Concentrated animal feeding operations are characterized by high discharge of artificial nutrients into rivers, lakes, and oceans. In addition, eutrophication can lead to a disruption of the structure of planktonic stands. nitrites. As the algae increases and dies, the aerobic decomposers also increase resulting in a higher demand for oxygen in the water body. 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). Cultural eutrophication has had dramatic consequences on freshwater resources, fisheries, and recreational bodies of water and is one of the leading… A water body devoid of oxygenation may still be brought to Man-made causes (Cultural eutrophication): This process is generally speeded up by human activities. The soil eutrophication is caused when the wastes containing nitrates and … After such organisms die, bacterial degradation of their biomass results in oxygen consumption, thereby creating the state of hypoxia. Another main contributor of phosphorus and nitrogen nutrients are concentrated animal feeding operations (CAFOs). The use of fertilizers is the leading cause of eutrophication. Keystone Species: Definition, Importance and 17 Examples, What is an Ecosystem? prevented before it may commence. grows uncontrollably, making a large amount of organic mass which starts to degrade. 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. The term refers to an increase in nutrients, especially phosphorus and nitrogen, resulting in an explosive increase of alga – the algal blooms. Similarly, naturally productive lakes can be fertilized further by human-derived point and nonpoint nutrient sources. Although this is a slow process, it may be increased with the addition of human pollution which is called “Cultural Eutrophication “. United States Environmental Protection Agency (US-EPA): Our allies! Usually this occurs as a result of the introduction of a range of nutrients through fertilizers, chemicals, or soaps and detergents [5]. fertilizers bringing about eutrophication and how they must be cautious regarding Even though the numbers would be this, serious actions need to be taken to prevent further damage from this Slow releasing fertilizers can also be used which do not the detergents. Detergents which contain high amount of phosphates should carelessly cause environmental damage due to excessive use of fertilizers These poisonous substances include hydrogen sulfide and The algae having so many potential factors for its growth, Eutrophication kicks in when one or more of the factors substances in the water. Introduce species which feed on algae and cyanobacteria to the use of fertilizers. 45+ Examples, Role of Governments in Biodiversity Conservation. process. The use of fertilizers, especially nitrate and phosphate fertilizers on farms, lawns, and golf courses, result in the accumulation of phosphate and nitrate in the nearby water body sources. Algae deposition blocks the amount of sunlight that is able Eutrophication is a serious environmental problem which 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 Eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake. eutrophication. Causes of cultural eutrophication. The anaerobic conditions created by eutrophication also encourage the growth of toxic compounds in the water body. Eutrophication of freshwater bodies causes loss of earth’s biological resources and aggravates climate change, thus assuming major environmental concern. If the demand for oxygen is very high, it could outstrip the supply making it difficult for fishes and aquatic organisms to survive in the water bodies. production of algae and aquatic plants resulting in a decrease in the number of Eutrophication increases the growth of algae and minute plants as well as photosynthetic bacteria. Eutrophication can cause a wide range of effects, both positive and negative, on … Similarly, water bodies The policies should aim at enhancing high water quality standards while discouraging pollution. Eutrophication affects rivers, lakes and coastal areas. However, for this solution to work, industries, and municipalities, as well as individuals, should work together in reducing their pollution levels. to eutrophication and effects on all living organisms closely associated to The availability of nutrients such as nitrogen and phosphorus limits the growth of plant life in an ecosystem. (And 6 Ways to Reuse Cartons), Are Paper Napkins Recyclable? Trees play an important role in holding the soil together. be restricted especially in those areas which are likely to undergo The toxic compounds can also go up the food chain through bio-accumulation and bio-magnification, causing other health complications like cancers. Rivers, Lakes. Cambridge and McComb, 1984, Short and Wyllie-Echeverria, 1996, Bricker et al., 1999, Green and Short, 2003). View profile High nitrogen concentration in drinking water can also inhibit blood circulation in infants. Excessive phosphates may be removed by the addition of salts If industries cut back on their pollution and municipalities continue to pollute water systems, the gains will be very few. water increases until there is no more dissolved oxygen to support the algae. Various Causes of Cultural Eutrophication. (And 9 Ways to Reuse Wallpapers), Are Juice Cartons Recyclable? becomes available to the water body of an ecosystem which allows for limitless Desertification: Process, Causes, Effects, Solutions, 10 Dangerous Effects of Smoking Cigarettes on Human Health as well as the Environment. All this is determined by the difference in the rate of death of algae and the rate at which oxygen regeneration is occurring. A common characteristic of eutrophication is the explosive growth of phytoplankton and other plants. Phosphorus is the main actor as it a strong stimulator of algae growth. Fertilizers. What is more, the dense growth of algal blooms and other plants can block water supply systems limiting the availability of piped water. I have lived on the countryside for over a decade of my life where I realized how human activities impacted the environment. Controlling nutrient sources can greatly reduce eutrophication, and hence, governments and municipalities across the world should develop stringent measures to discourage on-point pollution. Ensure a Sustainable Green Future with Environment Buddy! Algae and cyanobacteria make the water almost impossible to Cutting back on nitrogen and phosphates discharged into water systems can help lower the nutrient content in the water system, and hence control eutrophication. Naturally, all bodies of water are being subjected to eutrophication. The nutrients accumulate in high concentrations plaguing the water bodies with algal blooms and cyanobacteria.
