The reading passage raises the issue that salvage logging benefits the forest and economy a lot. However, the professor in the following lecture contends that salvage logging may appear effective for recovering the forest, actually it will cause long-term environment damage and the economical benefits are also questionable.

To begin with, opposite to the standpoint demonstrated in the reading passage that removing the dead trees will help the forest recover from the disaster, the professor argues that cleaning up the dead trees do not necessarily create good condition for tree growth. This is because natural decomposition of the dead trees will enrich soil which is helpful for the growth of trees in future generation, rapid removal would result in soil lacking nutrients for tree growth.

In addition, contrary to the point presented in the reading passage that dead wood removal will decrease the damage caused by harmful insects, the professor asserts that dead trees may enhance the population of insects, but it is not bad for the forest. The spruce beetles have lived in the forest for more than 100 years, but they cause no damage at all. Other insects and birds will be attracted by the dead wood as well, which will play important roles in the forest ecosystem balance. In the long run, salvage logging will end up doing more harm than the harmful insects do.

Finally, although the reading passage claims that salvage logging will bring about economic benefits, the professor proves that this claim is specious. He points out that the economic benefits are small and will not last long. Much of the removal would need the help of helicopters and other vehicles which will be expensive. Furthermore, the jobs require outside workers who are experience and trained instead of the local people, so the residents would not benefit from salvage logging.

In conclusion, based on the evidence offered above, the professor successfully reveals that salvage logging will not benefit the forest recovery as well as local economy.
