causes and effects of wetland destruction

The act of deforestation (cutting down of trees) has impacted on the world in terms of depreciating the natural environment and wildlife. Jubete, F. (2004). The world coastal wetlands are faced with great pressure of being squeezed by human land use and sea-level rise. PLoS ONE, Leonard L.A. and Croft A.L. 2017. Wetlands help prevent erosion in 2 ways: 1) Wetland plants serve as a physical barrier by taking the punishment of the waves crashing into shore or the water running down a hill.

Land, air, and water pollution pose long-term cumulative impacts on the quality of the natural environments in which they occur. Res. The EPA also list the following as major human causes of wetland loss: logging, runoff, air and water pollution, introducing nonnative species. Mar. Impacts of biodiversity loss on ocean ecosystem services. Due to improper extraction of uses and misconceptions forwarded to wetlands, the health of the wetlands is continuously decreasing from time to time that in doubt their existence in the near future. Marani M., DAlpaos A., Lanzoni S., and Santalucia M. 2011. Res. Their presence ensures shelter and food for hundreds of fish, birds, invertebrates, amphibians, and mammals. Poffenbarger H.J., Needelman B.A., and Megonigal J.P. 2011. For years, people have drained or filled wetlands for agriculture or development, causing habitat loss as well as a decline in many other important wetland functions. Wetlands are among the most biologically productive ecosystems in the world. Invasive species often cause coastal wetland degradation. How effective were mangroves as a defense against the recent tsunami? Duarte C.M., Middelburg J.J., and Caraco N. 2005. Mitsch, W.J., and Gosselink, J.G. Mudd S.M., DAlpaos A., and Morris J.T. Das S. and Vincent J.R. 2009. This is the key finding of the first-ever Global Wetland Outlook by the Ramsar Convention, a globally treaty ratified by 170 countries to protect wetlands and promote their wise use. Conversion to agricultural use was the primary cause for most of the losses, but urbanization, reservoir construction, highway construction, and other activities also contributed. In the past, the societal and ecological value of wetlands were not widely recognized and many wetlands were destroyed. Massel S.R., Furukawa K., and Brinkman R.M. Biogeosciences.

Another type of habitat destruction is habitat degradation. The good news is that despite the significant amount of wetland destruction since European settlement in Michigan, 6.47 million acres of wetlands remain. Human activities cause wetland degradation and loss by changing water quality, quantity, and flow rates; increasing pollutant inputs; and changing species composition as a result of disturbance and the introduction of nonnative species. 2010. Bertness, M.D. Plant growth in wetlands provides a sink for many chemicals including atmospheric carbon. Environmental degradation through aspects such as over-exploitation of natural resources, pollution, and deforestation can contributes to the scarcity of resources particularly arable land, water, genetic resources, medicinal plants, and food crops. However, theyre in constant decline due to climate change and the expansion of industries that provide products for human use. Springer, Dordrecht. Coast. Salt marsh restoration experience in San Francisco Bay. Pollution impacts the chemical compositions of lands, soil, ocean water, underground water and rocks, and other natural processes. Iftikhar, U. Well answer these questions and many more in the following lines. They are also on the migration routes of 19% of the globally threatened migratory bird populations. The low water level allows for the establishment of all types of plants, which in turn support an enormous diversity of animals. Some of the reasons for deforestation include farming, construction, settlement, mining, or other economic purposes. Spatial and temporal variations in sediment grain size in tidal wetlands, Yangtze delta: on the role of physical and biotic controls. 2016. However, due to unbridled human development, most of the Earths wetlands are at risk or have disappeared.

Air pollution from automobiles and industries that results in the formation of acid rain which in turn brings about acidic lake is a good example of how the environment is degraded by pollution. Wetlands, or marshes, fens, bogs, and swamps, are the link between land and water. If we help in their conservation, we promote the long-term permanence of thousands of species that have wetlands as their home. This is because of the human activities such as acidifying water systems, over-exploitation of natural resources, overpopulation, and the deliberate and indirect destruction of natural systems necessary for the survival of different species. Majority of farmers resort to converting forests and grasslands to croplands which reduces the quality of natural forests and vegetation cover. Wetlands help prevent erosion in 2 ways: 1) Wetland plants serve as a physical barrier by taking the punishment of the waves crashing into shore or the water running down a hill. However, things soon turned around, as well see in the next section. When wetlands are filled, the water that made them wet has to go somewhere. The landfills discharge various kinds of chemicals on the land adjacent to forest, various natural habitats, and water systems such as underground and surface water which makes the environment unappealing to the survival of trees, vegetations, animal and humans. It is widely recognised that wetlands play an important role in the hydrological cycle, influencing groundwater recharge, low flows, evaporation and floods. Wetland losses around the world are truly dramatic. Geophys. Types of Wetland ImpactsHuman ImpactsNatural ImpactsTypes of Wetland Impacts, Sources of pollution have local and regional effects on the chemistry and quality of water flowing through wetlands.

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. Res. Before the 20th century, this lagoon was one of the most important wetlands on the Peninsula, covering almost 5,000 hectares during the wet season.

Human activities cause wetland degradation and loss by changing water quality, quantity, and flow rates; increasing pollutant inputs; and changing species composition as a result of disturbance and the introduction of nonnative species. Coastal wetlands include all wetlands in coastal watershedsthe entire area from which tidal streams drain to the ocean or inland seas. Altogether, the toxic wastes and harmful chemicals from factories, agriculture and automobiles cause illnesses and death in children and adults. Sustainable hydraulic engineering through building with nature. Incorporating ecosystem services into coastal planning will achieve greater returns from coastal protection and tourism than from achieving conservation or development goals only (, Moreover, while faced with quick economic development along the world coast zones, we also need to make room for potential sea-level rise. Ma Z.J., Melville D.S., Liu J.G., Chen Y., Yang H.Y., Ren W.W., et al. The National Geographic Society is a global nonprofit organization that uses the power of science, exploration, education and storytelling to illuminate and protect the wonder of our world.

The State of Maryland pledges to provide constituents, businesses, customers, and stakeholders with friendly and courteous, timely and responsive, accurate and consistent, accessible and convenient, and truthful and transparent services. An effective strategy for protecting coastal wetlands includes a coastal marine spatial planning effort focused on the shared goal of identifying future competitive uses and impacts. 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.
