Sea otters are a small mammal that lives in the waters along North America's west coast from California to Alaska. A few years ago some of the sea otter populations off of the Alaskan coast started to decline rapidly and raised several concerns.
In the set of materials, the reading passage states that the decline rate of sea otter populations is due to the environmental contaminants and the predator is attacking. Nevertheless, the professor refutes the author's opinion in the lecture and explains why the growth rate of these mammals is deteriorated, and it was due to the attack of predators to sea otters.
Firstly, the article posits that pollution sources are destructive factors. In contrast, the professor contends that it is not a correct supposition. There is no expectation about the sea otter fatality, and others think it is because of the infection. While not only orcas kill sea otters and eat them, but also they do not wash the rest of the otter's corpse that this case creates a doubt between people that they died from infections.
Secondly, the reading avers that another reason is decreasing of other mammals in this area. On the other hand, the professor opposes this hypothesis and mentions this point that hunting of whales is very active in the population decline of sea otters. The professor claims that because of numerous hunting of whales, the diet of orcas are changed and they begin to hunt more and more to make food. This is why the decline has occurred.
Ultimately, the passage indicates that ocean currents and environment factors are crucial to this problem. However, the professor avers that the attacks have uneven patterns, and they are accessible to be hunted. Also, the stable population of sea otters can be found in shallow Rocky locations that this theory conflicts by the reading passage.
