7 The following appeared in a letter to the editor of the Clearview newspaper.
"In the next mayoral election, residents of Clearview should vote for Ann Green, who is a member of the Good Earth Coalition, rather than for Frank Braun, a member of the Clearview town council, because the current members are not protecting our environment. For example, during the past year the number of factories in Clearview has doubled, air pollution levels have increased, and the local hospital has treated 25 percent more patients with respiratory illnesses. If we elect Ann Green, the environmental problems in Clearview will certainly be solved."
Merely based on some suspicious evidence and dubious sumption, the arguer draws a conclusion that the residents in Clearview should vote for Ann Green, instead of Frank Braun
in the next mayoral election. To prove the conclusion, the arguer point out that the air pollution levels increases during these years.Well, Ann Green, who is in the Good Earth Coalition, should be a better candidate for the mayor than Frank Braun, a member from town council. However, in my opinion,this argument didn’t testify his conclusion.
At first, the fact that more patients suffers from illness related to respiration lend no strong support to that air pollution levels have increased. There are many other explanations for that the number of people who get respiratory illness increases. Perhaps there is a serious epidemic illness in Clearview. Without ruling out all these possibilities, it’s unfair to say that environmental problem worsened in Clearview.
Secondly, even if air pollution level did increase during these years, the arguer fails to prove that Frank Braun should be responsible for this problem. It’s entirely possible that Frank Braun worked in the department of public health and he do care public health and related pollution issue. Therefore, the arguer’s concern is unfounded.
Last but not the least, the environmental policy may not be the key factor that determines voters’ choice. People may pay more attention on jobs, education, traffics and some other matters. Even if Frank Braun did not care much about the environments, and give promise to more jobs, better elementary school and new efficient government, people would still support him. On the contrary, If Ann Green overemphasize on environments and didn’t show a ideal governance program, nobody would choose her as the next mayor.
To sum up, the arguer fails to lend s strong credence over his conclusion. To be more convincing,
on the one hand, the arguer should provide more direct evidence on that air pollution got serious in these years and that Frank Braun was responsible for it. On the other hand, a survey on whether people in Clearview pay much attention on the environment should be conducted. With the given factors discussed above, the argument would have been more thorough and logically acceptable. |
