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 memo, the author attribute the population of fish declining in Tria, which is a marine sanctuary, to overfishing, not pollution, after compared with the marine sanctuary--Omni. As a result, the author recommends the measure that replacing our regulations with those of Omni. However, close scrutiny renders its fallacies, as discussing infra.
At the first place, the author make his conclusion that the reason for this declining is overfishing not pollution on the mere fact that Tria's fish declining, while Omni not, and Tria do not ban fishing, while Omni, do. I think this analysis undue in two aspects. First, the author refutes the reason of pollution, but did not provide any evidence to support this argument. Although Tria bans drilling in 20 miles, the oil and deleterious material could flow to Tria. Second, the author ignores other explanations for this declining other than overfishing. Maybe the food that the fish depend on declined, so the fish died of hunger. Or perhaps this season is the time of fish migration; many fishes go to other place to spend winter. Without ruling out these possible explanations, the author could not deduce his argument, as he did not provide any evidence related to overfishing.
Secondly, the author makes a false analysis of the relationship between Tria and Omni, only establishes his recommendation that we must use Omni’s regulations only due to their adjoining in geography. The differences between Tria and Omni may vary in climate, the species, the management, and so forth. It is highly possible that Tria’s fishes are frail, but Omni’s are strong. And maybe Tria is a new sanctuary, inclined to be influenced by the climate, while Omni established many years ago, not. And as for different protecting objective, Tria mainly in marine, Omni in all, the regulations of Omni may not suit for Tria, as fish is including to be protected. So, the author based his recommendation on ignoring these situations, which unadvisable.
Finally, this argument is unconvincing, due to lack of evidence and false analysis. To bolster it, the author should provide information on the pollution and the statistics of fishing. To better assess it, the author should compare the regulations of the two, with a scientific measure, in practical attitude. |
