The reading passage probe into the contention that forest fires and severe storms can cause a great deal of damage to forests, one method to cope with it is salvage logging which ,according to the article, is beneficial both to a damaged forest and to the economy. The professor's lecture deals with the similar issue, however, she holds that the appeared recovering that salvage logging brings may be harmful to the environment in the long run.
Initially, the cleaning that savage logging does undermines the growing condition of the trees. The lecture proves this by pointing out that the cleaning may cause the result that rich soil lacking
of nutrients which the forest needs. This point of view contradicts what the reading material demonstrates.
Moreover, despite the statement in the reading that insects that decaying wood brings about may be harm to the forest, the lecture proposes
another reasonable opinion that decaying woods may invite more umharmful insects as well such as birds which can be a contributing factor to the health of the forest in the long run.
The lecture's last stance concerns on the claim of the article that salvage logging has economic benefits both to the industry and the workers, the professor argues that this economical benefit does not last long, for the after-fire work shall be made by helicopters which are very expensive and the provided work opportunities are temporary. This argument made by the lecture is incompatible with the article's point.作者: dawn_horizon1 时间: 2011-2-14 21:39:43
