The reading and the lecture are both contradicting with each other, in terms of extinction of a huge marine mammal name as Steller's sea cow. The author of the article presented three theories about the reason for extinction. However, the lecturer casts doubt about the claim presented in the article and refutes all the ideas explained in the passage.
First of all, according to the article, one of the causes for extinction might be the reason of overhunting by the native Siberian people for their food source. On the contrary, the speaker undermines the argument presented in the paragraph. Furthermore, he discusses that Siberian people used to live in small groups, and on the other side, this animal was enormous in the number. So, even though they hunted a sea cow for their food source, but they did not need to hunt them in large amount which shows that they were not a cause for extinction.
Secondly, the author posits that they became extinct because of disturbances in the ecosystem that led to a decline in kelp plant which was the main food source for mammals. Although the lecturer refutes this by asserting that there were other marine animals were also declined if the ecological disturbances had occurred. Unfortunately, there were not data complaining about it. Thus, it was not a factor for extinction.
Finally, it is mentioned in the article that the European trader might have hunted the sea cow. On the other hand, the speaker believes that the sea cow was already reduced in the number when European came first in 1700. Hence, there would have some serious consequences occurred which lead to the extinction of a sea cow.
