With land forms such as this the less the trees are chopped down the better. I'm not stressing that all the felling done in the past was wrong, but if economic profits are our motivation for felling and we don't restrict felling, then the results of our actions will be very difficult to deal with.
但砍樹，由現場林木在地表拖著走，對地表的破壞；到水土保持不良會造成水庫淤積、市區颱風淹水等，損失的金錢可能更多。
