The geologic structure of the east and west coasts is vastly different, and just off the east coast there is a sea trench eight or nine thousand meters deep--so deep it couldn't be filled even if the whole Central Mountain Range could be sliced off and dumped in. Thus there is no hope of generating new land or reclaiming land from the sea by casting the rocks into the Pacific.
由於東、西海岸構造迥異，東海岸外幾公里就是八、九千公尺的海溝，整個中央山脈切割下來也填不滿，因此把砂石都搬棄於太平洋，也無法產生海埔新生地。
