tpo 10 the decline of sea otters along Alaska coast

tpo 10 the decline of sea otters along Alaska coast PVnDK
The material discusses the two causes that could explain why sea otter started to decline on the Alaskan coast. While the reading suggests that pollution is the main reason for this decline, the listening challenges this and mentions that predation is the most possible cause of sea otter's decline. First, the author states that pollution had known sources along the Alaskan coast from industrial chemical pollution, so it reduced the otter's ability to resist infection and cause their death. On the other hand, the professor opposes this and points out that pollution theory is weakened given that there were not dead sea otters. The lecturer adds that if the life-threating infection is the main reason of sea otter's death, we supposed to see many dead sea otters. According to the lecture, the absence of dead sea otters is consistent with the predation hypothesis, because predators already ate them, so they cannot wash up on the shore. Second, the writer states that other sea mammals, such as seals and sea lion were also declining in the same place, given that the environmental pollution affects many species, and orcas are the main predator in this area usually hunt whales. On the contrary, the professor refutes this and cites that ocars usually eat whales, but whales started to disappear because of human hunting. The lecturer explains that orcas had to change their diet, so they started to hunt other mammals, such as seals, sea lions, and sea otters, and this approach explains their declining. Third, the reading brings up that sea otter's decline happened in uneven pattern which supports the pollution theory because the pollution concentration is not equal along the coast. Conversely, the lecturer contradicts this and contends that uneven pattern of sea otter's declining supports the predation hypothesis rather than pollution. The professor statets that the decline happened according to the accessibility of orcas to the area. The speaker adds that ocars are very large, so they cannot access shallow water and rocky areas. the speaker mentions that these areas are precisely where sea otters are not declining.
