The reading states that the population of the yellow cedar is declining and provides three hypotheses to explain the reason. However, the professor explains that the researchers still do not know what kill these trees and he thinks that the reasons that the reading are mentioned are not adequate and he refutes each of the author's hypotheses.
First, the article claims that the insect parasites, especially the cedar bark beetle is attacked the trees by eating the wood. The professor refutes this point by saying that even healthy trees are more resistant to this kind of insects. He states that the bark and leaves of these trees have some kinds of chemicals that are poisonous to these insects and this substance kills them. Thus, these beetles are not the cause for death of these trees.
Second, the reading avers the bears that eat the tree bark which contain a high sugar content for them attributes the decline. However, the professor says that even though the bears damage some trees, but these trees exist in both island and mainlands and the bears are not living in islands. According to professor as these trees are declining in both places, thus bears cannot be the reason for their drop.
Third, the article posits that the gradual changes in climate may to be to blame as the timing of the root growth is changes and the sensitive roots suffer from partial freezing. The professor opposes this point by saying that the author forgot to account one important thing. Based on the lecture if the author is true, the trees in high elevation would die as the weather is colder and they are in danger of becoming frozen, but they found that trees in low elevation are dying more. Thus, the climate changes cannot be responsible for declining in number of these trees.
