The passage suggests three theories about cause of the extinction of sea sow. The lecture completely refuses the passage. The speaker states these reasons are not accurate.
Firstly, the article points out that the native people were the main cause of the extinction because of overhunting. However, the professor says that the sea cow was very mass and huge with a height of 9 miles and weight of 10 tons in normal. Meanwhile, the population of native people was small and there was a lot of sea cow. Although they hunted sea cows, they were unlikely to hunt so much. This is directly contradicts what the reading says.
Secondly, the passage posits that the ecosystem distances caused a decline in food so sea cow went extinct. However, the speaker mentions that not only the food for sea cows but also the food for other animals would be reduced by the ecosystem distances, but the amount of other marine animals, such as whales, were not reported to decline. So the sea cows were not experienced food shortage. This is another part where is contradicted the reading passage.
Thirdly, the reading argues that the extinction of the sea cows was caused by the arrival of the European fur traders. The professor rejected this by explaining that the amount of the sea cows was actually small by the arrival of the European. The amount of the sea cows was larger thousands of years ago. It become to decline long before the arrival of those people, so it is not reasonable to say that it was European who arrived at last that the reason of the extinction.
