The reading and the lecture are both about theories of the rapid decline in sea otter populations. Whereas the author of the reading states that pollution was the major cause of the decline in sea otter populations, the lecturer suggests that predation is the most likely factor contributing to the reduction in the number of the sea otters. The lecturer casts doubts on the main points made in the reading by providing three reasons.
First of all, according to the reading, the increased levels of pollutants taken from water samples provide evidence for the pollution theory. However, the lecturer disputes this point. He says that if the sea otters had been killed by pollutants in water, they would have been found on shores. Furthermore, he mentions that the absence of dead sea otters on shores indicates that sea otters were killed and eaten by predators.
Secondly, the reading states that aside from sea otters other small sea animals also decreased in population due to pollution. This finding indicates that the pollution is the reason why sea otters are in rapid decline. Nevertheless, the lecturer refutes this argument. He argues that because the whale population decreased, the orcas in the area had to eat otters instead of whales. As a result, the otter population diminished.
Finally, the reading claims that environmental factors, which lead to different levels of pollutant concentration, perfectly explain the uneven pattern of the diminishing sea otter populations. On the other hand, the lecturer believes that the uneven pattern of declining sea otter populations corresponds to the prevalence of orcas in different areas. He thinks that the otter population reduces in places with orcas and there was not a big decrease in otters in places where orcas could not access.
In conclusion, although the reading and the lecture are both about hypotheses of the diminishing sea otter populations, the three main points made in the reading are effectively challenged by the lecturer.
