Basically, there has been a debate about the cause of sea otters' population decline in North America. Is it because of environmental pollution or predation? The author in the reading passage supports the pollution theory and gives three evidence to strength his opinion. While the professor in the lecture strongly challenges these evidence and tries to convince their students with the predation theory.
First of all, the lecturer assumes that if the decline of the sea otter population is because the pollution as the author claims. So, we suppose to find otter bodies have washed out on beaches, but if they killed and ate by predators that would explain convincingly why we cannot find otters bodies on the beach. As long with this fact, the predation theory would dominate over the pollution theory at this point.
Second, the professor asserts that the extinction of the whales( the main food for sea orcas) forces the sea orcas to change their food, so they start to eat sea lions and sea otters instead. Clearly, the decline in a lot of small animal in the ocean can be explained strongly by the predation theory, as the sea orcas started to feed on them. By this point, the professor seriously refutes the second point in the text.
Finally, regarding the fluctuation in decreasing of the otters' population in different areas. The speaker contends that happen because the sea Orcas are large animals , so they are accessible to some areas and cannot reach other areas like rocky areas and areas with shallow water, so we can notice the decline in population in the area that accessible to the orcas and stability of otter's population in the other area. Admittedly, the professor digs a hole in the third evidence in the reading passage.
