the sea otter
The reading and the listening materials have a conflict of opinions about the cause of the decline of the sea otter which lives in the water of the western coast of North America from California to Alaska. The reading passage explains that the environmental pollution is a key factor in this issue. On the other hand, the speaker in the lecture indicates that the predators play a major role and she refers to three reasons.
First of all, the professor makes it clear that there are not found any dead otter on the beach so that it is obvious that the pollution cannot reason for this issue. In contrast, the writer in the passage refers to this fact the water samples revealed that the level of the pollution increases a lot in comparison to the past.
Second, the lecturer in the listening passage clarifies that the predator of the sea otter hunts the smaller mammals like the sea otter. Because they prefer to eat whales which are hunted by humans so that they have to prey small mammals. By contrast, the author holds the opposite view that due to environmental pollution, the population of different mammals is decreased and it has a bad impact on the ecosystem.
As a final point, the speaker believes that the uneven pattern of otter decline due to the predators that they are very large so that they cannot go to the rocky place and prey the otters. Thus, the otters are found a lot in the rocky or shallow places, but they are hunted by their predators in other places. On the contrary, the writer suggests that the pollution has a responsibility for the uneven pattern of otter decline.
