not cause a dramatic impoverishment in internationally shared biodiversity, as much as reclamation activities in Yellow Sea or Taiwan Strait areas. The problem of mentioned areas touches directly the fishing villages and their inhabitants, what became the backbone of this thesis. The negative results of reclamation are already huge and are still increasing. Firstly, this process worsen drought. The first symptomes were already noticed, especially in North China that suffer from very dry weather in recent years. It is related to many water areas that have already dried or have been build up. Dimnishing water areas, including wetlands as well, mean less evaporation and as a result reduction in rainfall. Secondly, reclaiming land areas lead to the loss of biodiversity and fisheries. Coastal shallows, swamps, mangrove forests and intertidal zones are the point, where the land meets the sea. Creating some artifical separator between natural land and sea will block nutrients flow into coastal waters. That, in turn, will threaten crabs, shrimps, clams and other organisms, which rely on this source of food. This has an impact on the ocean food chain and the fishing industry as well as some land-dwelling animals. Third, land reclamation along the shoreline increases the tidal range and the risk of flooding in these areas. Since always, wetlands have been a buffer zone between the ocean and the land - absorbing much of the ocean’s forces. The decay of this natural buffer can have potentially harmful consequences, including loss of human life and livestock. Fourth, reduction of the tides intensify also the so-called phenomenon of harmful “red tides�. The 3. Hong Kong in 1984 and in 2015
artificial barrier, that is built up during this process, pertract between land and sea and accelerate the flow of the nutrients from river deltas into the sea. In turn, on the coastal areas, where the wetlands were used for aquaculture before reclamation, the tides carry too large quantities of organic matter. And as a result trigger enormous algal blooms, producing toxic or harmful effects on people, birds and marine habitat. And fifth - the process of reclamation destroys natural landscapes. In the course of time, land is shaped and reshaped, and eventually reclaimed by movement of ocean waters. In that case, this is a slow process, so nature has time to adapt to the changes in environment. But if the changes take place too quickly, the process can cause huge damages and threaten not only the marine habitat but especially people living in coastal areas [3].
