The reading and the lecture are about the declining in otter populations. While the reading suggests that pollution is the main responsible for the decrease in the number of otter, the lecturer argues that predators are accountable for the otter´s disappearence. The audio casts doubt on the main points made by the reading by providing three relevant reasons.
First of all, the reading states that pollution along Alaska decreased the otter population, but the lecture affirms that predators, are the responsible for the lack of otter. First, the reading supports its theory by affirming that the increasing levels of chemicals in the zone killed other sea mammals, the lecturer, the lecturer refutes this point by arguing that there is a lack of otter´s bodies in the ocean so that predators are a better explanation.
Furthermore, the reading mentions that hunters prefer larger animals; However, the lecture shows that, given the lack of whales, preyers eat otters. Finally, the reading believes that the uneven decline in some Alaskan locations is because of pollution, but the lecturer explain that otters are more accesible than orcas to some places, and that´s why the uneven pattern exists.
In short, even though the reading and the lecture are about the same topic, they mantain different points of view about the responsible for the declining in the otter populations. The lecture effectively challenged the three main reasons given by the reading.
