The negative impacts of floods and sea level rise in the coastal area are expected to increase significantly in the middle of the century, showing an emergence that residents’ life and property safety is in great danger. The natural coastal habitat can protect humans from the influence of the rising sea level and storms. However, due to centuries of overexploitation, habitat transformation, and pollution, our coastal habitat have been degrading and destroying greatly, which is also undermining biodiversity and coastal ecological resilience. Statistics show that human activities have depleted 99% of previously important species, undermined 96.5% of seagrass and wetland habitat, degraded water quality, and accelerated species invasions. Over time, 67% of wetlands, 65% of seagrasses, and 48% of other submerged aquatic vegetation were extinct. (Lotze 2006)

According to a research, human impacts to coastal habitat deterioration and rapid diversity depletion concentrate on two global market periods, 1900–1950 and 1950–2000. There were rapid growing of human population and increasing demand for resources, industrialization and technology explosion. Conservative actions have slowed the trends of coastal habitat degradation in developed countries, but In developing countries, with predicted future population growth and increasing demand for consumption on natural goods, the pressures on coastal ecosystems will increase degradation. (Lotze 2006)

There are three strategies that help protect coastal habitat. Ecosystem-based management, coastal conservation, and invasive species control. Reduced exploitation is necessary to mitigate the damages to coastal habitats from human activities. The reduction effect can greatly improve water quality and coastal habitats resilience. Education for the public on conservation of marine resources is the first step of coastal conservation. In addition, invasive species control is an effective way to keep potential invaders out in the first place.
