Effect of UV rays on the population (GRE® argument)

[Sprasad89]

Discuss how well reasoned this argument is

It is known that in recent years, industrial pollution has caused the Earth's ozone layer to thin, allowing an increase in the amount of ultraviolet radiation that reaches the Earth's surface. At the same time, scientists have discovered, the population of a species of salamander that lays its eggs in mountain lakes has declined. Since ultraviolet radiation is known to be damaging to delicate tissues and since salamander eggs have no protective shells, it must be the case that the increase in ultraviolet radiation has damaged many salamander eggs and prevented them from hatching. This process will no doubt cause population declines in other species, just as it has in the salamander species.

This piece of argument describes the effect of the thinning of the ozone layer on the population as a whole. Though at first it seems to be very well reasoned out, there are quite a few fallacies, which need to be addressed for it to receive complete credibility.

The amount of ultraviolet radiation has increased over the years because of the thinning of the ozone layer. It has also been discovered that the species of salamander is on the decline. But relating these two events in a cause-effect relationship might turn out to be a huge blunder. There might be many more unexplored phenomena that might have caused this decline in the species.

The lack of a protective shell might certainly be playing a part in the damage of these eggs. But there might be a possibility where this factor does not contribute to the damaging process to the same extent as some other unaccounted reason. The increased exposure to the ultraviolet rays might not be the main reason in this scenario.

Even assuming that this decline is caused because of the harmful effects of the ultraviolet rays, this cannot be generalized to other species. There might be many other species that are impervious to these rays and might continue to exist even with its increased penetration.

On the whole, though it seems that ultraviolet rays are the primary reason for the decline in the salamander species, it requires some credible evidence to conclude the same. The author has to provide sufficient facts and figures for his argument to be meritorious.

The lack of a protective shell might certainly be playing a part in the damagING of these eggs(,) but there might ALSO be a possibility where this factor does not contribute to the damaging process to the same extent as some other unaccountABLE reason. The increased exposure to the ultraviolet rays might not be the main CULPRIT in this scenario.

Even assuming that this decline is caused because of the harmful effects of the ultraviolet rays, this cannot be /generalized/EXTRAPOLATED TOWARD/ other species.
