The result can be catastrophic. This commitment represents our best opportunity to preserve the ecosystems necessary for our survival. Habitat loss is primarily, though not always, human-caused. Studies reveal that by protecting 50 percent of the land and ocean around the world, plant and animal species could thrive. Key Takeaways Key Points. Despite the habitat loss that has occurred globally to date, there is still hope. Studies reveal that by protecting 50 percent of the land and ocean around the world, plant and animal species could thrive. Habitat Destruction . The situation is even worse in waterways, coastal areas, and the ocean. ... Kathleen Reaugh/Marine Photobank. The Marine Habitat destruction and loss is where the marine environment or the ecological set up is unable to support life due to degradation. This implies that when the natural habitat is encroached or even destroyed, such species or animals and plants become extinct. Where are sharks and rays affected (or unaffected) by habitat loss? Most marine habitat destruction is caused by pollution, commercial fishing equipment, coastal development, and other human activity. It will upset … Habitat destruction is the process by which natural habitat is damaged or destroyed to such an extent that it no longer is capable of supporting the species and ecological communities that naturally occur there. Describe the effects of habitat loss to biodiversity and concept of sustainability . Overfishing can render certain animal species extinct due to the deprivation of food. Lead author Petr Keil of the German Centre for Integrative Biodiversity Research, noted that current methods only consider the amount of area lost, rather than where it is lost, when estimating species extinctions. About one-fifth (20%) of marine coastal areas have been highly modified by humans. Of these, clear-felling, aquaculture and over-exploitation of fisheries in mangroves are expected to be the greatest threats to mangrove species over the next 10–15 years [29] . These fertilizers always contain phosphate and nitrate ions and when they come into contact with the waters; they form basic and acidic compounds thereby leading to dense growth of algal blooms, which in return create intolerable environment that cannot support aquatic life. Where governments have failed to acknowledge the importance of conserving the natural habitat, there is higher probability that negative impacts will be made. In the present, habitat destruction effects on a large scale, constantly destroying habitats such as oceans and rainforest which leads to biodiversity loss. In many cases, countries rely on the shipping means of transport for bulky cargo. Since 1888, National Geographic has pushed the boundaries of exploration, investing in bold people and transformative ideas, providing more than 14,000 grants for work across all seven continents, reaching 3 million students each year through education offerings, and engaging audiences around the globe through signature experiences, stories and content. There are some 1,200 invasive species in European seas, 6 … How would this happen? Habitat destruction drives wildlife away, sometimes to extinction. This is a process that is contributed by various natural and human activities. Here are the various causes of marine habitat loss and destruction. Most countries have had the opportunity to stock marine animals and plants. » Chapter 7: Niche and habitat – Essays on Wildlife Conservation, by … Habitats are destroyed by: Destructive fishing activity: bottom trawling and dynamiting coral reefs destroy entire ecosystems. The primary reason for this would be that they add the beauty of a country. 9 The practice also practice destroys corals, oysters and sponges that form productive marine habitats. High winds, heavy rain, storm surge, and flooding associated with these disasters can pull large structures, household products, and outdoor items into surrounding waters. Other policies can be formulated which support and give guidance on what needs to be done during coastal urbanization to preserve the marine habitats. What activities have the greatest and the least impact? Human discipline would be quite necessary in ensuring that the problem of marine destruction is solved. In addition to the loss of habitat, deforestation reduces the ability of forests to provide the critical benefit of absorbing carbon, which helps to mitigate the effects of climate change. Even with management practices now in place, fisheries have major impacts on ocean environments, ranging from direct harvest to by-catch effects, habitat destruction, genetic changes, and food web changes. The end result is the depletion of marine animal and plant species. Due to the existence of water transport, many countries develop a consequential drive to develop their coastal regions. (And Which Foods Do They Actually Like), What is Flora and Fauna and Importance of Flora and Fauna, Why is Biodiversity Important and Reasons For Loss of Biodiversity, How Do Birds Mate? The beauty of the coastal places is dictated by the variety of plants and animals that are existing. How Does Photosynthesis Take Place in Desert Plants? Poverty, consumption and land-use patterns contribute to the degradation of marine habitats and to the destruction of the species that rely on them to survive. One-fifth of coral reefs have also been destroyed, and another fifth has … Animals such as whale, shark and many others depend on other aquatic ones such as seals for food. Scientists explain that when there is higher concentration of carbon dioxide in the air, the water absorbs much of it. Monitor and test water quality. Deforestation far from shore can cause erosion that enters the water and deposits silt into the shallow marine waters, blocking the sunlight that coral reefs need to survive. Eutrophication can be understood as the process where the fertilizers from land are washed off into the waters. Such human activities can be moderated by limiting land conversion drive. Eventually, global warming shall have been controlled and the threat posed to the aquatic lives will have minimized. When uncontrolled, human settlements can be a nuisance to the existing ecosystem. Protected Areas Save Critical Habitat Like national parks on land, Marine Protected Areas (MPAs) can be used to protect biologically rich ecosystems and help restore overfished populations. The first measure that would be useful in combating this environmental threat would be the step to control environmental pollution. © 2020 . Countries such as North and South Americas, South Africa, Brazil and continents such as Europe Asia and many others are bordering water masses. This may benefit humans for settlement but other benefits drawn from the aquatic life will surely vanish. Marine pollution also affects human health indirectly. The destruction has the potential to kill off habitats, plants and animals that live in the ocean ecosystem. Natural disasters can be causes of habitat destruction. There is evidence to suggest that human activities have caused the amount of carbon dioxide in our atmosphere to rise dramatically. Perhaps, various environmental conservation bodies such as UNEP can be in liaison with the various governments so that laws seeking to control industrialization and waste disposal are ratified. The ocean faces the threat of ocean destruction on a daily basis. Causes and Effects of Coastal Degradation ... posing a threat to the near-shore habitats such as coral reefs. Approximately 15 billion trees are cut down each year. This can be achieved through the strict use of designate routes in order to limit the spread of danger that can be caused by the ships. Contact Us. When we use the natural resources and exhaust them to the fullest, the homes of many animals are lost during the process. Approximately 15 billion trees are cut down each year. The clearing of land for farming, grazing, mining, drilling, and urbanization impact the 80 percent of global species who call the forest home. (And Which Foods to Avoid), Can Squirrels Eat Raisins? Diamond (1984, 1989)referred to these as “the Evil Quartet,” an analogy to the 4 horsemen of the Apocalypse, and concluded that habitat destruction and fragmentation were the most important agents of species extinction in the 20th century. Also read: Which species face the biggest threat from habitat loss? The whole consequence of the marine habitat loss and destruction is that it leads to death and migration of animals. Plants and animals will then suffocate. Earth Eclipse. When she is not writing, she loves watching sci-fi movies on Netflix. This implies that over time, many animal and plant species may die off. Despite the habitat loss that has occurred globally to date, there is still hope. The extinction takes away the beauty of the coastal areas because its natural aspect is taken away. Can Squirrels Eat Bread? It obviously limits the concentration or the solubility of oxygen in the water. Fishing regulations can therefore help in giving guidance. Coastal estuaries and marshes provide breeding grounds for the majority of marine species. The marine habitat destruction and loss is where the marine environment or the ecological set up is unable to support life due to degradation. Her passion for science education drove her to start EarthEclipse with the sole objective of finding and sharing fun and interesting science facts. Today, only 15 percent of the land and 7 percent of the ocean is protected, leaving us with a challenging yet attainable goal. But while this research has confirmed that habitat destruction deeply influences the way species interact, until now we have lacked a full understanding of the effects of habitat … Water, air and soil pollution are responsible for the adverse climatic changes. Natural disasters. Even when the physical structure of a habitat is being preserved, … The organisms that previously inhabited the site are displaced or die, thereby reducing biodiversity and species abundance. When the ocean temperatures rise; there are other associated adverse impacts that are experienced in the aquatic environment. According to a. , the number of trees worldwide has decreased by 46 percent since the start of civilization. Habitat destruction can have a significant impact on marine biodiversity as species richness, abundance, distribution, genetic variation and inter-population dynamics are affected and entire ecosystems are altered by the loss of habitat. In addition to the loss of habitat, deforestation reduces the ability of forests to provide the critical benefit of absorbing carbon, which helps to mitigate the effects of climate change. As they, along with inland wetlands, are dredged and filled, species are less able to birth and support their young. Habitat destruction drives wildlife away, sometimes to extinction. Human and mother nature share blame in Marine Disasters or ocean habitat loss. Some mining methods cause further destruction, such as the use of explosions to destroy mountain tops. Seafloor trawling, in which equipment is pulled across the seafloor to catch bottom-dwelling fish, decreases the biomass and production of benthic species. But in the process, less or no concentration is rendered on the need to conserve the natural marine habitat and all that it contains. By definition, habitat is an ecological area that is inhabited by particular animals, plants or other types of organisms. Ecologists agree on few things; nonetheless, there seems to be general agreement that the most important agents responsible for recent extinctions are habitat destruction and fragmentation, the impact of introduced species, chains of extinction, and overkill. Draining wetlands creates threat for local aquatic flora and fauna. Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. Examples of natural disasters that can be devastating include earthquakes, floods, and tornadoes. Learn about the ongoing, tragic consequences of human actions. The increase in temperature has another aeration negative impact. The Campaign for Nature calls upon world leaders to take action in helping to protect 30 percent of the Earth’s land and ocean by 2030, on the way to 50 percent of the planet in a natural state by 2050. The destruction of habitats (also sometimes referred to as habitat loss or habitat reduction) can be defined as a state in which the natural living conditions of natural habitats are no longer suitable to support native species. Overfishing tampers with the aquatic ecology and food chain. article Naturally Resilient. When the marine habitat is destroyed and is at the brink of vanishing, there various effects that would be likely. The water gets contaminated and the level of heat in the water rises beyond the expectations of life. (And Are They Still Growing), LEED Certification: Why Do You Need it and Process to Apply For it, How Can Animals Drink Dirty Water? All Rights Reserved . In addition to direct habitat and species destruction, seabed mining will release a sediment plume that may drift over large areas of the ocean, suffocating or blocking sunlight from organisms in the deep sea or that live in the water column. As a consequence, plants and animals will be endangered. Native plants suffer, too. Annually, 57 million hectares are destroyed, in other words, an area similar to the surface area of the entire seabed. Other effects of marine pollution – An increase in oceanic temperature through pollution leads to an interruption in the natural water equations causing the unconditional death of innocent water animals. It often results in the extinction of species and, as a result, the loss of biodiversity. There are some human activities which are responsible for the changes in the marine ecological conditions and such may mean alteration or destruction and loss to the marine habitat. Too much aggressive fishing activity can damage the marine habitat as it leads to the loss of many fish and aquatic species. In the case of marine habitats, when there are no policies regulating access to such areas, sea plants and animals will shoulder the burden of irresponsible acts. The primary threats to all mangrove species are habitat destruction and removal of mangrove areas for conversion to aquaculture, agriculture, urban and coastal development, and overexploitation. This can be as a result of water or air pollution which even makes the water to be contaminated. This impacts on the marine environment as the world’s oceans currently absorb as much as one-third of all CO2 emissions in our atmosphere. Because there is some degree of dependence between the terrestrial and aquatic lives; the former will be hit by the depletion of the latter. article Five Questions for Richard Carson, Natural Resource Economist. Fishing is still thought to be the leading threat to marine life, but experts are increasingly concerned about the threat of pollution, alongside habitat destruction and climate change. The first major impact that acts as the determinant and influences the outcome of the others is that oxygen concentration in the water gets to the lower level, to the extent that it can barely support aquatic life. The effects are least severe when a habitat dwindles in random pockets. But while this research has confirmed that habitat destruction deeply influences the way species interact, until now we have lacked a full understanding of the effects of habitat … A significant example that can be cited in this particular scenario is that humans depend on some sea fish such as octopus, star fish, salmon and much more for food. To learn more, visit. When they are depleted, humans will definitely suffer from that negative impact. According to a study about tree density published in Nature, the number of trees worldwide has decreased by 46 percent since the start of civilization. Not only do the sandy beaches attract people but also the picturesque view of the aquatic plants and animals play crucial roles. But coastal areas, with their closeness to human population centers, have suffered disproportionately and mainly from manmade stresses. Here are 25 destruction of ocean habitat. Coastal regions are major tourist attraction sites. This can be as a result of water or air pollution which even makes the water to be contaminated. A natural disaster has a huge potential of ruining an ocean habitat in numerous … Habitat loss is called habitat destruction and it occurs when humans destroy the natural shelters of the wildlife. There are other associated activities that can be used constructively. Sonia Madaan is a writer and founding editor of science education blog EarthEclipse. Great Barrier Reef Marine Park, Australia, is a network of fully protected areas within a larger protected area, designed to protect all habitats … Such changes result into glaciation, melting of the icebergs and in the process, the marine habitat is threatened by degradation.
