The author of the passage demonstrates tree theories about the main cause of the extinction of Steller’s sea cow, a huge marine mammal, while the lecturer in the lecture is opposed to all of them.
To begin with, the author claims that native Siberian people may have overhunted sea cows for food. However, the lecturer rebuts that it is not the case. Steller’s sea cow is a massive mammal with 9 meters height and up to 10 tons weight, thereby a small one can feed the Siberian for months. Besides, the population of Siberian at that time was considerably small. So, even if the Siberian did hunt the sea cows, it is unlikely for them to do it in an extant so great that can cause the extinction.
Moreover, the author believes ecosystems disturbances have caused the sea cows’ main source of food, kelp, to decline. On the contrary, the lecturer refutes the occurrence of such a disaster. If the disturbances were so severe, it would not only affect the sea cows but also have influence on other parts of the ecosystem such as whales, but it has never been reported. This indicates that there were not broader ecosystem problems that could probably lead to sea cows’ food shortage, let alone the extinction.
Finally, the author puts forward the hunting of European fur traders could be the main cause of the extinction. Instead, the lecturer retorts when the traders first arrived in Siberia, the sea cows already had a small population. Evidence have proved that it is hundreds of years before the traders’ arriving that their population reached the peak. As a result, the population decrease started long before that time, ruling out the possibility that European fur traders drove the sea cows to extinct.
