Essay topics: 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 because of their important role in the coastal ecosystem. Experts began investigating and came up with two possible explanations. One explanation was environmental pollution and the second was attacks by predators.
At first it seemed as if the pollution was the most likely cause for the population decline. One reason pollution was more likely was because of the known pollution sources along the Alaskan coast such as oil rigs. Also water samples taken in the area showed increased levels of chemicals that could decrease the otters' immune systems and indirectly result in their deaths.
Another thing that pointed to pollution as the culprit was the decline of other sea mammals such as seals in the same areas. This indicated that whatever was affecting the otters was also affecting the other sea mammals. Environmental pollution usually affects an entire ecosystem instead of just one species. Only predators that occurred in a large area, such as orcas (a large predatory whale), could cause the same effect, but they usually hunt larger prey.
Finally, scientists believed the pollution hypothesis would also explain the uneven pattern of otter decline. In some Alaskan locations the otter population declined greatly while other populations remained stable. Some experts suggested this could be explained by ocean currents, or other environmental factor, might have created uneven concentrations of pollutants along the coast.
<span style="font-size: 19.36px;">The author and the lecturer both discussed about the declining population of sea otters. In the article, the author has mentioned three major reasons for decrease in sea otter's population.Hoever, the lecturer has contrasting opinions and has provided supporting reasons. Let us have a look on their explainations.
firstly, the author claimed that the decline in the sea otter's numbers is majorly due to pollution and not by predators.In order to support this view, the author mentioned a compelling reason that oil rigs near sea have increased the pollutant which is harmful for the sea otter's health and could somehow becoming the reason for sea otter's death. On the other hand, the lecturer refutes claim provided by the author and says that dead bodies are not found on the sea shore, which should need to be the case if they are dying because of the pollution and hence, they are being attacked by predators and they are consuming them for food as there is no evidence of foodies on the sea shore.
Secondly, the author posits that large sea habitats like whales are being hunted by the predators and due to this imbalnce sea otter's population is getting low.But the lecturer presents another side of which undermines the assertion made by the author . According to which, the Whales are migrating to different place and hence reducing their populations and hence, making predators prey on smaller species.
Moreover, the author maintains that due to the uneven change in currents and other climatic parameters, sea otters are declining.Whereas, the lecturer rebus this explaination of the author by mention that with the help easy accessibilty due to rocky sea area predators are easily hunting the sea otters</span><br>
