decreasing in otter population
The passage and the lecture discuss why the sea otters population of the Western coast of America started to decline. Although the author suggests three reasons to prove that environmental pollution is the main reason for the declining sea otters population, the professor believes that attacking by predators decreases the sea otters pollution.
First, the passage explains that recently, the level of chemicals that infect the sea otter has increased. However, the lecture believes that as there are no dead sea otters on the beach, the predators ate them.
Second, the text claims that, as the number of other small mammals such as sea lion decreased, environmental pollution should be the reason. The predators such as orcas, a large predatory whale, hunt the big animals, not the small species. Hence, the reduction in other species is due to pollution, not predation. On the other hand, the speaker explains that the orcas' diet change because humans predate whales. Thus, they hunt other species.
Third, the passage believes that the inconsistent pattern of animal declining is caused by uneven concentrations of pollutions along the coast. In contrast, the lecturer states that because of the orcas, there is an uneven pattern of mammals dwindling. As the orcas are so big, they could not access shallow or rocky locations. Hence, the sea otters population in these places is not reduced.
In conclusion, although the passage believes that environmental pollution is the reason for the declining mammals' population, the lecturer refutes all the passage reasons and believes hunting is the main reason.
