write based on reading and lecture
The article states that the progressive decimation and its effect of extinction of the Steller's sea cow was due to the overhunting of human being and it upholds three reasons as support. However, the professor explains that the reasons ascribed upon extinction are not exact, rather they are meaningless and he refutes all three of the reasons with proper logic.
First, the reading claims that sea cow was annihilated by dint of the overhunting by the native Siberian people as they were the predominant people in the 17th century at that time. Moreover according to this theory, as there were no other species like that rife so there were significant chances of extinction by them. Here it is also referable that harsh environment didn't suppress sea cow as they tolerated and easily were habituated to it. Turning to the other side of the logic, the professor refutes by saying that obviously such full extinction is only possible by the huge number of people. What he means by this is that at that time density of Siberian people was very lower and it is well-substantiated. Besides, the height of sea cow is 9 meter and weighs 10 ton. As a result, it is quite onerous that so easily small population of Siberia engrossed it.
Second, the article posits that disruption of the organized ecosystem was the prime source of extinction since sea cow lived on kelp which was totally degraded by the harsh environment. Therefore, it can be said, the main source of food, kelp was decimated by imbalance of ecology which caused their ruins. On the other hand, the lecture says that by far it is well known that if kelp was decimated, so obviously others plants were also annihilated. In consideration of it, whale's main food was also destroyed but it was present then. Actually it provides evidence that ecosystem disruption is an illogical way to make it a fake conclusion.
Third, the reading says that at the 1741 suddenly European trade was extensive and those people were very fond of hunting. Which is why they might hunt sea cow myriad that caused this disruption. In this logic, the professor is very obstinate to accord in it. Eventually he says that sea cow's progressive decrement was result of the previous decade of 1700. That's why it is a hard nut to crack to say wittingly that European people are liable to do this. Rather he says that in the meantime of 1741 the density of sea cow was very negligible. So European trader's hunting might not be an ideal and prime reason to their extinction.
