听力材料:
Salvage logging may appear to be an effective way of helping forests recover after a destructive fire or storm, but it can actually result in serious loner-term environmental damage. Its economic benefits are also questionable.
回收性砍伐看起来似乎是个帮助森林从破坏性大火或者暴风雨中的损害中恢复的有效方法,但是事实上却会带来长期的环境损失。而它的经济利益也是存疑的。
First, cleaning up a forest after a fire or storm does not necessarily create the right conditions for tree growth. In fact, the natural process of wood decomposition enriches the soil and makes it more suitable for future generations of tree. The rapid removal of dead trees can result in soil that lacks the nutrients necessary for growth.
首先,在大火或者暴风雨之后的清理并不一定会给树的生长提供合适的生长环境。事实上,树木腐烂的自然过程可以使土壤变得肥沃,更适合以后树木的生长。迅速地移除死去的树木可能会导致土壤确实树木生长所必须的营养物质。
