tpo 10 sea otters declining
The material discusses the possible reasons that cause sea otter's declining. While the reading claims that the pollution hypothesis is the more likely reason, the listening disagrees and mentions that the predation theory is the most suitable explanation.
First, the author states that the decline happened along the Alaskan coast, where there was a lot of industrial chemical pollution. On the other hand, the professor refutes this and posits that if pollution is the reason, so there should be died sea otters. The lecturer adds the absence of killed otter because the predators ate them. The speaker explains that consistency with the predation theory.
Second, the writer contends that there were other mammals in the same area that were declining too. On the contrary, the lecturer opposes this and states that orcas used to eat whales, and when whales disappeared, they had to search for other food sources to survive. The professor says that orcas hunted other mammals, such as sea lions, seals, and sea otter. As a result, their numbers declined.
Third, the reading states that the uneven pattern of declined could strengthen the pollution hypothesis. Conversely, the professor contradicts this and points out that uneven pattern of declining because orcas could not access all places evenly. The lecturer adds the orcas are very large so they could not access shallow and rocky places. The speaker states that shallow and rocky places are the locations where sea otters have not declined.
