The reading passage proposes three main benefits that salvage logging could bring. The lecturer, however, points to the inaccuracies in each of the reason and states that the action can make longer term damage.
To begin with, the reading passage claims that removing dead trees can expand space for living trees. On the other hand, the professor argues that it will disturb the nature process of wood decomposition. This action will lead to a lack of nutrients in the soil which is harmful to future tree generation.
Second, the reading passage states that salvage logging will reduce the damage caused by harmful insects like spruce bark beetle. On the contrary, the professor contends that spruce bark beetle has been living in the forest for hundreds of years without causing damages. Besides, the removing of trees can make some birds and other beneficial insects leaving too.
Moreover, the writer asserts that the salvage logging is beneficial for economy. However, the professor points out that the economic benefits are small and do not last long. The action needs helicopters and other expansive vehicles to transport the woods. In the meantime, this job requires experienced and skilled workers rather than local people.
In the final analysis, the professor convincingly shows that none of the explanation in the reading passage provides sufficient support for the statement that the salvage logging could bring benefits.
