declining of population of sea otters

declining of population of sea otters 2bPnx
The passage and the lecture both discuss the reason of quickly declining in the numbers of sea otters in that has a significant effect on region's costal ecosystem. Both explain two dominated explanation about decrease in population of them, environmental pollution and predators. The passage claim that the pollution explain this event more convincingly in comparison to attack by predators and give three reason for this. Even though, the lecture denies all those reason and states that the reason of attacking by predators is more conceivable. First, according to passage, existence of industrial chemical materials like oil rigs along the Alaskan cost, is an important evidence for declining of this kind of animal by pollution of industrial factories. In contrast, the lecture denies this assertion by stating that there were not any dead sea otters along this coast, so it is not possible pollution caused death of this animal. While declining in population of this animal without any evidences of their dead bodies can be explained more conceivable. Second, the reading points out that pollution explanation is more likely true because of death some other mammals like seals and sea lions. It can be explained by universally pollution effects on the entire ecosystem. But, the lecture state that orcas changed their diet from whale to small mammals because of decreasing the numbers of whale causing by human hunter. So, they ate small mammals like seals and sea lions besides sea otters in order to survive. Third, the reading says that irregular pattern of declining them could happen by environmental factors like ocean currents. By contrast, the lecture contends that this uneven pattern can be justified better by large size of orcas. In fact, they weren’t able to pass thorough shallow water and rocky place because of their large size. As the shallow water and rocky place are the location with stable sea otters' population, considering reason of decrease in the number of sea otter is more reasonable and conceivable.
