the sea otter populations off the Alaskan coast rapidly declining
The reading passage states that the sea otter populations off the Alaskan coast rapidly declining because of pollution, However, the professor in the lecture casts doubt on the points made in the lecture.
First, considering the article, environmental pollution such as oil and industrial chemical sewage seemed the more likely cause of decline in the population of sea otter. In contrast, the professor in the lecture contradicts the idea and further explains that predator effects are a more reliable cause for declining because researchers didn't find any sea otter' s body and this point represented that maybe predators kill them and consume of their body.
Second, the reading claims that other sea mammals on the coast also declining and environmental pollution affects the entire ecosystem. Admittedly, the professor justifies the information presented in the reading and makes the point that maybe orca hunts other mammals as consequent of declining sea otter.
Third, the author in the reading passage puts forward the idea that pollution hypothesis could explain the uneven pattern of otter decline. In the same way, the speaker validates the idea and adds that this event happened because of the different distribution of orca all around the coast.
To sum up, the writer and speaker both hold a conflicting view about the declining population of an otter. It's clear that they will have trouble finding common ground on this issue.
