The lecturer and the writer are both talking about sea otters, which are decreasing in number in some places. The author says that the main cause is pollution. The lecture cast doubts on the claims made in the article. He thinks that predators are responsible for the fast declining of sea otters.
First, the present investigations report that predators are guilty for this phenomenon. There aren't enough proofs, like dead bodies, to demonstrate that pollution is causing their death. If this fact was true, the sea would wash up their bodies on the shore. Instead, the lack thereof shows that their disappearance is linked to the existence of predators, such as the orca. This is a strong counter-point that contradicts the author of the article.
Second, humans over-hunted big whales which represent the main source of food for orcs. The author states that pollution affected the entire ecosystem, killing both sea otters and mammals. However, the lecturer says that orca started to hunt small mammals as an alternative for feeding. This is another standpoint that contradicts the passage.
Third, a visible declining of these animals was noticed in accessible place for orcs. Since orcs are big mammals, they are able to hunt only in wide spaces. Therefore, they cannot enter in shallow and rocky locations, places where the number of mammals is still stable. This fact is directly contradicting the passage, showing that the uneven pattern is linked to the place accessibility, not to the currents that might have spread chemical substances. Not to mention that there are no traces of pollution in the areas where mammals has disappeared. In conclusion, the author and the lecturer appear to be in total disagreement regarding this topic.
