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."

In this argument, the author concludes that people in Tria should abandon their regulations and  adopt those of Omni to restore Tria's fish populations and protect all of Tria's marine wildlife since the declining of Tira's fish population is due to overfishing while the fish population in Omni is reported not declining significantly. To support this conclusion, the author points out that the decline of fish populations in Tria is due to overfishing rather than pollution.  The author also notes that Omni reports no significant decline in its fish population. However, this argument suffers from several flaws and is therefore unconvincing as it stands.

First of all, the author assumes that the decline of fish population in Tria is due to overfishing rather than pollution. The author overlooks many other factors that can lead to such a result. For instance, the decline of fish populations in Tria is because local factory dumped some poisonous liquid into the sea and thus the fish are killed. Or perhaps more mammals come to Tria from other places and they eat more fish. Without ruling out these and other explanations for the change of fish populations in Tria, the author cannot make a sound conclusion based on such an assumption.

Secondly, the author overlooks the differences between Omni and Tria which may bring different results in Tria by adopt Omni's regulations. There may be several distinct factors between the two places and thus the regulations of Omni may not proper to Tria. For instance, there are many fishmen requiring fishing to feed themselves while there are not in Omni. In this situation, banning fishing in Tria is not feasible. Also, the mammals live in a range of 15 miles of Tria, which is larger than 10 miles in the regulations of Omni and applying this for Tria would lead to some mammals in Tria are outside the protect of the sanctuary and in dangerous situation.

Finally, the author assumes that adopting Omni's regulations can restore the fish populations in Tria and protect all of Tria's marine wildlife best. The author makes a hasty conclusion. Perhaps there are better regulations than those of Omni, for example, banning dumping, offshore drilling and fishing in 30miles near Tria to enlarge the area of the sanctuary. Or keeping large ships from the Tria is good for wildlife. Without consider these and other factors, the author cannot concludes that the regulations of Omni are the best for Tria.

In sum, this argument is unpersuasive as it stands. To bolster this conclusion, the author must provide clear evidence that the decline of fish populations is because of overfishing and that the Omni's regulations can offer Tria the same effect as in Omni. To better assess the conclusion, more information about the decline of fish populations in Tria and more detail about the regulations in Omni are needed.
