The reading and the lecture are both discussing the cases of sea otter decline in Alaska. The author of the reading believes that they have declined because of pollution. The lecture casts doubt on the claims made in the article. He says that reason of sea otters decline is predation.
First of all, the author points out that water samples contained a lot of chemicals that could be cause sea otters death. This point is challenged by the lecturer. He says that if water contamination was the reason for their death we would found dead otters. But we did not, because predators attacked the otters and eat them ride away.
Secondly, the author contends that pollution usually affects the entire ecosystem this is why not only otters but also other sea mammals in Alaska such as seals and sea lions were declining. The lecturer rebuts this argument. He says that some spices have just disappeared from that area, not because of the pollution. He also adds that orcas are probably the predators that cause the otters decline.
Finally, the author states that because of the uneven environmental contamination sea otters declined differently among Alaska. The lecturer, on the other hand, posits that the decline has an uneven pattern because orcas cannot access rocky locations, so the sea otters population in that area did not change. Meanwhile in other open areas where orcas can swim otter declined significantly.
