Forests reclaiming land from the sea: Besides having the functions of recreation and moderating natural disasters, coastal wetlands can also clean pollutants from upstream waters. Thus various nations spare no effort in their preservation and are trying in every way to "cultivate" beaches and coastal forests through human effort.
除了遊憩、制衡天災等功能，海岸濕地又可以淨化上游沖刷而來的汙物，因此各國保護不遺餘力，也極力想以人為方式「復育」海灘和海岸林。
