The passage and lecture are both about the causes of Sea otters population decline. While the passage mentions environmental pollution as a possible explanation for this event, based on ongoing investigations, the lecture states that the real cause of Sea otters decline is related to predator attacks.
First, in the passage, the author mentions pollution as the most likely cause of Sea otters decline, using the oil rigs sources along Alaskan coast as an example. The author also mentions an increase of chemicals in water samples, which might be related to their deaths. On the other hand, the lecture refuses the pollution hypothesis pointing to the lack of dead Sea Otters on Alaskan beach coasts. Considering that no dead animals are found, the professor believes this supports the predator’s hypothesis since they eat their preys right away.
Second, the author talks about how the environmental pollution affects the whole ecosystem, causing the decline of other sea mammals in the same areas, which indicates that they are being as much affected as the otters. Nevertheless, in the lecture, the professor mentions that orcas rather hunt whales, but due to human hunters, these wales are disappearing. In light of this, orcas are forced to hunt what is available, creating a decline in all of the species mentioned in the passage.
Finally, the passage mentions scientist’s belief that pollution would explain an uneven pattern of Sea otters decline, due to the fact that other populations remained stable. In contrast to this, the lecturer states that predator’s hypothesis is a more likely reason for the pattern’s change since orcas are not able to hunt in all locations, such as shallow rocky locations.
