tpo 33 sea cows' extinction
The material discusses the causes of Steller's sea cows' extinction. While the reading looks at the topic from one perspective, the listening challenges certain points outlined in the reading passage.
Firstly, the reading details specific points regarding this topic, namely the Siberian people overhunted sea cows. Next, a change happened in the ecosystem that affected the population of sea cows' main source of food. Finally, the European fur traders hunted the last sea cows.
Conversely, the lecture challenges the points one specific contradiction is, sea cows were massive and each one weighed 10 tons, so a couple of them were enough to feed Siberian people for a month. As a result, Siberian people did not need to hunt a lot of sea cows. In addition to that, the hypothetical decline of kelp due to ecosystem disturbances before 1768, supposed to cause a drop of other marine populations, such as whales; however, there are no indication of this. Therefore, kelp populations were stable, and sea cows did not have experience of food shortage. One final point, sea cows populations were quite small before the arrival of the European fur traders after 1741. The decline happened in 1700, so there was a serious change consider the main cause of sea cows' extinction.
