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."
Based on the fact that the number of factories in Clearview(C) has doubled, air pollution levels and patients with respiratory illnesses have increased, the author assumes that the current members of C town council are not protecting environment. Then the author concludes that they should elect Ann Green (AG) instead of Frank Braun (FB) in order to solve the environmental problems in C. This argument, however, contains several logical flaws, which render it unconvincing.
First of all, the author unfairly assumes that the increasing factory number count for air pollution and respiratory illnesses. No evidence mentioned in the argument can support this assumption. Perhaps, the air pollution is caused by waste gas blowing from nearby towns. In addition, it is entirely possible that most of patients with respiratory illnesses in C town’s local hospital are coming from other town because C town can provide a better medical treatment. Without ruling out other possibility, the author cannot convince me that increasing factories in C caused air pollution and respiratory illnesses.
Secondly, the number of factories has doubled does not indicate that C town council are not protecting environment. Maybe these new-built factories are just project of sewage treatment, refuse reclamation and other green enterprise. Without more information about the type of these factories’, the author cannot draw any conclusion about the C town’s attitude towards environment.
Thirdly, even if the C town council would not like to protect environment, it does not indicate that FB will also hold the same attitude. Perhaps, FB devotes to protect environment while the C town council fails to do so. For that matter, it is possible that FB’s impact is not heavy enough to influence the decision made by C town council.
Thirdly, even if FB has no willing to protect environment, the author provides no evidence to prove that AG will surely protect environment as well after being selected. To be a member of Good Earth Coalition does not indicate that AG will surely commit herself to environment protection. Perhaps the publicity of AG’s identity involve in Good Earth Coalition is just a campaign measure. Without more detail about the Good Earth Coalition, the author cannot conclude that AG will solve the environmental problems in C.
In sum, the argument is unconvincing as it stands. To strengthen it, the author must provide more information about the Good Earth Coalition and the attitude of environment protection between AG and FB. To better assess the argument, we need also to know the background of the patients with respiratory illnesses and more detail of the increasing factories. |
