The article discusses the main causes of extinction of Steller's sea cow that lived in the waters around bering island off the coast of Siberia and provides three reasons of support. However, the professor claims that we actually do not know what happen exactly that cause extinction of this animal and he refutes each of the author's reasons.
First, the reading suggests that overhunting by a certain population of Siberian people leads to extinction of the sea cows. The professor argues this point by explaining that the size of sea cows are huge in the way that if these people hunted a small number of the sea cows could feed them for a month. Therefore, the professor emphasizes that there is no need to hunt a lot in order to provide food for Siberian people.
Second, the article claims that ecological disturbance could haven caused extinction of sea cows because they lacked their source of food, which is known as kelp. On the other hand, the professor proposed that if this hypotheses is correct, so all the ecological system should be affected, and we would have to see other animals are extinct or become decline in population. According to report, there is no evidence that suggest decline in marine population like whales. The professor concludes that sea cows and other marine animals were growing fine and there is no food shortage.
Third, the article states that European fur trader could have been the real cause why the sea cows were extinct. The professor disagrees with this point for the reason that when European arrived to the land, the sea cows had already become decline in population. Also, the professor explains that extinction of the sea cows have been happened hundreds years before European arrival. As the result there are no relation between fur trader people and extinction of the sea cows.
