sea otter population decrease

sea otter population decrease lj12D
The reading and the lecture are both about decrease in sea otter population. The author provides three theories to prove that environmental pollution is the most likely drawback of sea otter population decrease. In contrary, the professor is not convinced of this and cast doubts on each of the theories presented in the reading. This lecturer is of the opinion that based on the accurate evidence and observations, predation can motive this population decrease. To begin with, the author argues that the existence of many sources of environmental pollution in Alaskan coast such as oil rigs alongside with experimenting water sample that reveals high level of chemical pollution authenticate the pollution theory. This argument is challenged by the lecturer. According to the professor, if this theory was the main reason of the population reduction, many dead bodies of these creatures would be washing up in beach; whereas the predators are unable to leave such an evidence behind. Furthermore, the lecturer asserts that finding no evidence of dead sea otter support the theory of predation. Secondly, the writer disputes that, the decline in other mammals such as sea lions can be delineated by whatever that is responsible for sea otter’s death. Moreover, it is stated in the article that predator like Orca hunts large prey such as whales. In contrast, the lecturer stance is that other mammals’ death is, again, has something to do with predation. The professor elaborates on this idea by bringing up the point that when human hunts lead to whale disappear, sea otter change its diet and eats mammals. This food chain confirms the population decrease. Finally, the author averts that uneven population reduction certify the environmental cause. To delineate, ocean currents and other natural factors accounts for the population reduction. The lecturer opposes this notion by asserting that this phenomenon is happened because of the predators’ accessibility to sea otters. It puts forth to the idea that Orca has no access to shallow or rocky parts of the ocean; hence, the population of otters fluctuate or decrease in specific parts.
