The reading and lecture both discuss the reasons behind sea cow extinction. While the reading sttaes three theories of sea cow extinction, the professor refutes, saying we really do not know the causes of extinction.
Firstly, the reading shows that exaggeration hunting of sea cow was the cause of extinction. However, the professor argues this idea by explaining that sea cows were very massive creature. Also, they were very long and they weight many tons. So, there was not any need to Siberian people to hunt all of these fish as a source of food. As a result, this was not a cause of extinction.
In addition, the article avers that the dramatic changes in the ecosystem caused sea cow extinction. On the other hand, the professor rejects this notion by pointing out that if any something happened before 1768 should haad effect on other fish population. However, there was not any records about any other marine decline. He sates that there was not any report about wheels decline. As a result, sea cow did not expose to any food shortage.
Lastly, the reading states that fur traders caught many sea cow and killed many animals. Nevertheless, the professor questions this point by saying that soon after the European fur traders arrived, see cow already were a quit small longer before like hundreds of years. So, European traders were not the reason behind sea cow extinction. Furthermore, whatever somethig happened to the marine that was the cause of extinction is who are the last to arrive.
