The Great Lakes watershed has lost 62 percent of its original wetlands, and some parts of this region have lost, Wetlands destruction has increased flood and drought damage, nutrient runoff and water pollution, and shoreline erosion, and triggered a decline in wildlife populations. The loss of habitat has far-reaching impacts on the planets ability to sustain life, but even with the challenges, there is hope for the future. New benefits for those people must be explored, such as ecotourism, apiculture, and horticulture. Majority of farmers resort to converting forests and grasslands to croplands which reduces the quality of natural forests and vegetation cover. Am.

Pollution and effluents from the land travel easily through streams and rivers to the ocean, where they impact the health of fish, birds, and marine plants. 2015. Wetlands destruction has increased flood and drought damage, nutrient runoff and water pollution, and shoreline erosion, and triggered a decline in wildlife populations. The study assesses the nexus between the drivers of wetland utilisation patterns, land-use and land-cover change (LULCC) and the current status of provisioning and cultural services in Driefontein . 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. In the case of any doubt, it's best to consult a trusted specialist. Climate change could change wetlands forever, but in turn, wetlands can also help to mitigate the impact of climate change.

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. The soil instability of gully banks, usually associated with seepage of groundwater, leads to sloughing and slumping (caving-in) of bank slopes. Besides, occurrences such as hurricanes and flooding can wash or force the migration of invasive species into foreign environments which can lead to its eventual degradation.

Mitsch, W.J., and Gosselink, J.G. Local governments may also take action to protect wetlands from development, by enacting ordinances that meet state guidelines. Sediment budgets and ratios of mud, sand, and organic matter in the soil of deltaic plain are generally unknown, yet are crucial for preventing drowning (, From an academic point of view, the challenge for coastal wetlands restoration is also a great opportunity for landscape ecologists to transfer their knowledge into practice. 2014. But the production of Chinese fishery is mainly from aquaculture (>70%) (, Coastal wetland reclamation often results in the destruction of spawning and nursery ground for many marine species, while birds lose their food and shelter with more disturbed habitats. For example, considering the Midwest of the United States alone, some studies estimate that from 1850 to 1930, humans drained a minimum of 125 million acres of wetlands for agriculture.

Rooth J.E. etlands collect and store water from the surrounding landscape during rain or snow- melt. Mining and oil exploration, for instance, renders land unusable for habitation and causes other forms of environmental degradation by releasing toxic materials into the environment. Nebraska has lost about 1 million acres of wetlands in the last 200 years--about 35 percent of the State's original wetland acreage. Shuoben Bi. Remote sensing monitoring and spatialtemporal variation of Bohai Bay coastal zone. Coastal engineers generally estimate that a 1 foot rise in sea level will cause beaches to erode 0.5 to 1 feet from New England to Maryland, 2 feet along the Carolinas, 1 to 10 feet along the Florida coast, and 2 to 4 feet along the California coast. Eng. Zhang K.Q., Liu H.Q., and Li Y.P. Estuar. What are 3 major causes of degradation and loss of wetlands?
