TPO-10 - Integrated Writing Task
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 muchlarger 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 reading passage and lecture have conflicting points about what reason lead the otter's population to decline. The article strongly postulates that decreasing otter's population is harmful to the environment because they play a prominent role in their ecosystem also it is caused by pollution rather than predators. On the other hand, The listening adamantly delineates that current investigation has resulted that the main reason is predators because of several compelling reasons.
First and foremost, According to the author of the excerpt that their surrounding area is polluted by chemical substances and oil rigs which are reducing the otters' resistance to life-threatening infection so it affects their population adversely. Nonetheless, The professor offsets these points by declaring that along the Alaskan beach no one has found any death otters also it is expected predators may eat them.
On top of this, the professor in the listening elaborates by bringing up the point that the sea large predator orcas prefer to eat whales but they usually disappear because people hunt the whales so they have to prey on small sea animals such as otter, seals and sea lions. these claims refute the writer's implication which about the contaminated area influenced on the all species than one single population and it is not reliable that orcas feed them due to its preference is whales.
The text lastly insists that Alaskan other species remain stable but otter's population are significantly decreasing so the pollution centres along the coast. The speaker in the lecture counters these indications by asserting that it depends on locations due to the fact that orcas are so immense and the usually easily prey on along the shallow coast which is the main living area of otters.
