The reading passage explains that sea otters have declined in the Alaskan beaches because of the pollution, giving reasons to support this theory. However, the speaker in the listening passage refutes the pollution theory, referring the decline of the sea otters to the predation rather than the pollution.
First of all, the reading passage states that sea otters have declined, due to an increase in the levels of chemicals. However, the speaker explains that, if pollution is the reason then dead sea otters should have been found on the Alaskin beaches, and because there aren't any, then sea otters must have been eaten by their predetars
Secondly,the reading passage also mentions that the decline of other sea mammals such as the the sea lions and the seals is another proof that such a decline is due to pollution, adding to this, that the Orca( a big whale) could not be the reason, because it prefers larger preys. On the otherhand, the speaker does not agree with this argument, explaining that larger preys could have been caught by hunters, the fact that promoted the whales to change their diet to smaller mammals instead.
Finally, according to the reading passage, the increase in the decline of sea otters at certain locations is due the variation of pollutants along the cost. Nevertheless, the speaker clarifies that this point is better explained by the Orca predation, as the whales can not really reach the shallow locations where the sea otters have not actually declined.
