argument 第6篇
TOPIC: ARGUMENT131 - The following appeared in an environmental newsletter published in Tria Island.
"The marine sanctuary on Tria Island was established to protect certain marine mammals. Its regulations ban dumping and offshore oil drilling within 20 miles of Tria, but fishing is not banned. Currently many fish populations in Tria's waters are declining, a situation blamed on pollution. In contrast, the marine sanctuary on Omni Island has regulations that ban dumping, offshore oil drilling, and fishing within 10 miles of Omni and Omni reports no significant decline in its fish populations. Clearly, the decline in fish populations in Tria's waters is the result of overfishing, not pollution. Therefore, the best way to restore Tria's fish populations and to protect all of Tria's marine wildlife is to abandon our regulations and adopt those of Omni."

By making a comparison of Tria Island, which regulations ban dumping and offshore oil drilling whthin 20 miles of Tria and fishing is not banned, with Omni Island, which regulations ban dumping, offshore oil drilling, and fishing within 10 miles of Omini, the author concluded that the decline in fish populations in Tria's waters is the result of overfishing, not popullution and therefore, the best way to restore Tria's fish populations and to protect all of Tria's marine wildlife is to abandon our regulations and adopt those of Omni.
The argument is problematic in several critical places.
First, the author assumes that the decline in fish populations in Tria's waters is due to population or overfishing, rather than other possible alternations. This may not be the case. Perhaps the decline in fish populations in Tria's waters is the result of the move or the climate. It is possible that the climate of Tria Island changes a lot, so the fish is not adapt to its weather. In short, without ruling other possible alternations, the author should not conclude that the decline in fish populations in Tria's waters is the result of population or overfishing.
Secondly, even if the decline in fish populations in Tria's waters is the result of overfishing or population, the author also can not say that it is the result of overfishing rather than population. In Tria Island, the regulations ban dumping and offshore oil drilling within 20 miles of Tria, but in Omni Island, the regulation s ban dumping and offshore oil drilling without limit. So, it is possible that the decline in fish populations in Tria's waters is due to the population.
In sum, the argument is not convincing as it stands. To strength the argument the author should rule out other possible alternations and provide other evidences to improve that the decline in fish populations in Tria's waters is the result of overfishing rather than other alternations. |
