In the given sets of materials, the main topic is whether predation or pollution caused the otter's population declined. While the author has focused on the explanation of how pollution could play a significant role on this trend, the speaker in the follow-up audio material cast doubt on those points by providing justifications.

Last but not least, the writer stated that uneven pattern in otter population also could be explainable based on pollution hypothesis. Contamination along the sea area has made otter to spread erratically. Conversely, according to the lecture, some huge animals like orca were not able to access in shallow or rocky locations. So the population declined in these specific places.
