Shaped by nature over long periods, the shoreline has been damaged and thrown out of balance by man in various different ways. Some areas of shoreline have experienced erosion, others accretion. Everywhere the shoreline ecology has changed dramatically. Many animals and plants haven't adjusted well to these dramatic changes, and their numbers have greatly diminished or they have disappeared from these Taiwan coastal ecologies altogether.
種種人為干擾都會使長時間經大自然「波流作用」後才形成的海岸地形受到破壞而失去平衡，有些區塊發生侵蝕，有些岸邊則堆積土沙，致使四周海域生態環境改變，棲息其中的生物因為無法適應這些「山崩地裂」而減產或消失。
