Wetlands destruction has increased flood and drought damage nutrient runoff and water pollution and shoreline erosion and triggered a decline in wildlife populations. 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.

Some research has estimated that 87% of the Earth's wetlands have disappeared since the 19th century. Runoffs of agricultural wastes and chemical fertilizers and pesticides into marine and freshwater environments have also deteriorated the quality of wild life habitats, natural water resources, wetlands and aquatic life. Li X.Z., Ren L.J., Liu Y., Craft C., Mander U., and Yang S. 2014. And what can we do to prevent this? <<7B56AB1413FEA741B02CDCD02B0E9BE4>]>> Wetlands support a wide range of human activities such as commercial fishing, shellfishing, and other industries, as well as recreation, education, and aesthetic enjoyment.

Geology. Condition is difficult to measure because it is made up of many different attributes, and each wetland has its own unique baseline condition, function, hydrology (water flow), and combination of plant and animal species. In many cases, the ocean-front block of these islands is 5 to 10 feet above high tide; but the bay sides are often less than two feet above high water and regularly flooded. Hygiene ideas that associated wetlands with disease and the mechanization of agriculture have been the main forces leading to the disappearance of wetlands throughout history. The agricultural development plans of past times saw certain areas as uninteresting and unnecessary. Winter grazing (after seed dispersal and before seedling growth in spring) probably has a low effect on survival and reproduction, although there could be some trampling of rosettes, while spring and early summer grazing probably reduces growth, survival, and reproduction. As they, along with inland wetlands, are dredged and filled, species are less able to birth and support their young. The EPA also list the following as major human causes of wetland loss: logging, runoff, air and water pollution, introducing nonnative species. Due to environmental degradation, the results include water scarcity and decline in quality foods. Yee A.T.K., Ang W.F., Teo S., Liew S.C., and Tan H.T.W.

Huang X.W., Wang W., and Dong Y.W. Primary productivity: the link to global health. As the sea rises, the outer boundary of these wetlands will erode, and new wetlands will form inland as previously dry areas are flooded by the higher water levels. More importantly, when restoring the ecosystem occupied by aquaculture, the income of local people should not be reduced. Understanding and predicting wave erosion of marsh edges.

Ecol. The amount of dryland within a few feet above the wetlands is much less than the area of wetlands that would be lost if sea level rises a few feet. Destruction of wetlands is also detrimental to our regions economy: recreation like fishing, hunting, and wildlife watching generate more than $22 billion annually. Most disturbances that result in direct impacts to wetlands are controlled by State and Federal wetland regulatory programs. 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.

Degradation of the environment has recorded a continued destruction of wild forests and the damage of natural ecosystems that has greatly contributed to the mass extinction of species. Bruno J.F. A 3-foot rise in sea level (for example) would enable a 15-year storm to flood many areas that today are only flooded by a 100-year storm. Pollution impacts the chemical compositions of lands, soil, ocean water, underground water and rocks, and other natural processes.
