▶ Your Answer :
Both the reading passage and the lecturer from the listening focus on the method of using the tamarisk beetle as a solution to cease the tamarisk tree from draining the water source. While the reading passage argues that taking advantage from the beetles has some drawbacks, the lecturer opposes to these shortcomings, explaining that the objection to the method is overstated. First, the lecturer goes against the statement that it is nearly impossible to control the spread of the beetle. According to the reading passage, the tamarisk beetles could be detrimental to the environment as they are an invasive species, being difficulty to be managed. On the other hand, the professor from the lecture objects to this notion. To be specific, he states that the beetle only consumes one food, the tamarisk tree. In addition to that, natural predators including wasps can make it easier for the people to control their spreading across the continent. On top of that, the lecturer from the listening alleges that making use of the tamarisk beetle shows an immediate influence. In the article, the author asserts that the damage from the beetles takes about three to five years for the tamarisk tree to die out. During the period, the tree would continue to consume the water. However, the professor from the lecture is doubtful about this view from the article. According to his explanation, this tree eating insect soon consumes all the leaves of the trees, preventing the trees to utilize photosynthesis, the process in which trees get their nutrients and energy from water and sun light, and thus having an enormous impact on them. To end with, the lecturer claims that the risk of wildfire is not increased by the use of the tamarisk beetle. As proposed in the reading passage, dead leaves are left as a consequence of the solution of using the tamarisk beetle. These leaves are easily flammable, being highly likely to contribute to the occurrence of wild fires. On the contrary, the lecturer believes that the possibility of happening of wildfires is rather not severe. This is thanks to the fact that the government officials in the region possess numerous experiences in stopping the wildfire. For example, they get rid of the fallen leaves by extinguishing them before the wildfire happens. In conclusion, the lecturer from the listening counters the three reasons the author suggests, why applying the tamarisk beetle to eradicate the tamarisk tree should be avoided. |
