Argument Essay 7: Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands were extinct.

Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands were extinct. Previous archaeological findings have suggested that early humans generally relied on both fishing and hunting for food; since archaeologists have discovered numerous sites in the Kaliko Islands where the bones of fish were discarded, it is likely that the humans also hunted the mammals. Furthermore, researchers have uncovered simple tools, such as stone knives, that could be used for hunting. The only clear explanation is that humans caused the extinction of the various mammal species through excessive hunting.

Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation(s) can plausibly account for the facts presented in the argument.

Although at first glance it might appear admittedly that, the above statement is highly supportive however close scrutiny reveals that the above arguments are not enough to support the statement given by the author.

Firstly the author argues that after 3000 years of arrival of human to Kaliko Island, a large number of mammal species have been extinct. However he did not mentioned any other factors like eco-system effects, and climate changes in the area. Moreover he also failed whether the species have left the habitat due to the environmental changes. Additionally he also undermines one of the other possibility is that human might have consumed the plants and animals on which the extinct species used to depend on for their food.

Secondly, further analysis reveals that author mentions archaeological findings which were conducted earlier showed that human hunted for their food, which although convinces us to a large extent, however he did not any mentioned any possible hunters other than human being. Since the author is talking about the forest, there must be many more hunters due may be the reason of extinct of the specific mammals.

Thirdly, his statement regarding the simple tools works against the extinction of such a large population of the mammals. Such instruments cannot be reason of huge extinction of the mammals. This point impedes to believe the statement which he has mentioned before. However, the author also did not mention any other possible way of hunting other than the small stone knives, which seems unrealistic to the reader.

Lastly, the existence of the bones of fish is in any case not a good determinant of the human being and it cannot be the only reason for the extinction of the species. In this point the author only assume in the absence of any authentic argument.

Considering all the things, we fail to accept the author’s claim that only human can be the reason of extinction. The author needs to provide us some more reason for the accomplishment of his statement.
