Essay topics: The sea otter is a small mammal that lives in waters along the western coast of North America from California to Alaska. When some sea otter populations off the Alaskan coast started rapidly declining a few years ago, it caused much concern because sea otters play an important ecological role in the coastal ecosystem. Experts started investigating the cause of the decline and quickly realized that there were two possible explanations: environmental pollution or attacks by predators. Initially, the pollution hypothesis seemed the more likely of the two.
The first reason why pollution seemed the more likely cause was that there were known sources of it along the Alaskan coast, such as oil rigs and other sources of industrial chemical pollution. Water samples from the area revealed increased levels of chemicals that could decrease the otters' resistance to life-threatening infections and thus could indirectly cause their deaths.
Second, other sea mammals such as seals and sea lions along the Alaskan coast were also declining, indicating that whatever had endangered the otters was affecting other sea mammals as well. This fact again pointed to environmental pollution, since it usually affects the entire ecosystem rather than a single species. Only widely occurring predators, such as the orca (a large predatory whale), could have the same effect, but orcas prefer to hunt much larger prey, such as other whales.
Third, scientists believed that the pollution hypothesis could also explain the uneven pattern of otter decline: at some Alaskan locations the otter populations declined greatly, while at others they remained stable. Some experts explained these observations by suggesting that ocean currents or other environmental factors may have created uneven concentrations of pollutants along the coast.
The article and author are both about sea otters. The author of reading feels that some sea otter populations rapidliy declining a few years go. The lecturer challenges the claims made by the lecturer. The lecturer thinks that ongoing investigations have revealed that prediction is the most likely cause of sea otter decline after all.
First of all, the author argues that chemical polution help to decrease the otters. The article is mentoned that such as oil and other sources of inductial chemical level igoing increase and it could indirectly cause their death. This point is challenged by the lecturer. He claims that there are no dead sea otters or others by chemical polution in Alaskan beaches. Furethermore, he says that some otters can be killed by apredator.
Secondly, the author suggests that orcas hunt many sea anilmals likke as atters.The artcile notes that crcas preffer to hunt much larger pry such as whales.The lecturer rebuts this argument. He suggests that orcas hunt only smaller sea mmamals now available. The lecturer elobarates on this by mentioning that orcas prefer to hunt whales but they are disappered becuse human hunter.
Finally, the author states that some locations in otters declined greatly and some location in Alaskan at otters remained stable. Moreover, the article says that ocean current or other environmental factors have creat uneven the otters.In contrast, the lectutrer's position is thatocars can't access shallow and rocky locations. therefore those places otters population not declined. He says ocars where can access to the, those place which otters population in there can be decrease.
