Sea otters are a small mammal that lives in the waters along North America 039 s west coast from California to Alaska A few years ago some of the sea otter populations off the Alaskan coast started to decline rapidly which raised several concerns becau

The author in the reading states that the possible reason behind the decline of the sea otter population is environmental pollution; in contrast, the lecturer disagrees and has a different opinion: the probable rationale behind the decline is not the pollution but the attacks by predators - the orca.

First, the author states that the pollutant sources near the Alaskan coast have reduced the otter's resistance to dangerous infections which is leading to otter's death. However, the lecturer refutes this claim. She goes on to say that there were no dead bodies of otter found along the seacoast, if pollution was the reason, then they would have found the dead bodies. She holds that the predators killed and then feasted on these otters, and as result there were no bodies found on the coast.

Second, the author claims that the vast variety of other species were also found to be vulnerable, and their population also decreased. The pollutant had its effect on the entire habitat. Once again, the lecturer founds problem in the author's argument. She contends that the otters fed on these species; therefore, their population were also found to be declining.

Finally, the author posits that the uneven pattern of the otter death in certain location were found. These pollutants were unevenly concentrated due to the ocean currents or environmental factors, and these resulted in that pattern. However, the lecturer opposes this claim by explaining that the orca would come to the shallow waters to hunt the otters. Also, the pattern found showed the same thing - the population of the otters were more in the shallow regions than the deeper regions of the ocean.
