The article states that sea otters numbers have declined rapidly because of environmental pollution, and it provides three compelling reasons. However, the author disagrees with the article and states that predation is the most logical reason.
To begin with, the article says that oil rigs along the Alaskan coast is one of the reasons of otters decline, the professor refutes this by saying that no otter's bodies have washed up the shores, which would be explained by predators eating otters.
Additionally, the articles mentiones the decline of other mammels in the exact places owing to environmental pollution. The professor says that whales which are eaten usually by orcas have decreased in number due to human hunting. He explains that orcas have started to eat otters as a result of this.
Lastly, the article points out that uneven patterns of otter numbers is due to pollution. The professor opposes this by telling us that the unevenness of otter numbers is a consequence of the accessibility of otters to Orcas. He mentions that shallow rocky areas are harder to enter by orcas which explains why otters live in larger numbers there.
And that's how the professor taught us the real reason of otters population significant decrease in numbers.
