TPO-34 - Integrated Writing Task A huge marine mammal known as Steller’s sea cow once lived in the waters around Bering Island off the coast of Siberia. It was described in 1741 by Georg W. Steller, a naturalist who was among the first Europeans to see

The reading introduces three possible reasons for the extinction of the Steller's sea cow, a huge marine mammal that once lived around Bering island off the coast of Siberia. The lecturer refutes all the given reasons and refutes each one of them.

First, the reading states that the first possible reason for the extinction of these mammals is hunting . The native people used it as a source of food. The lecturer, however, refutes this claim by stating the these animals has a huge massive size, and just one animal was able to feed very large numbers of people. With the relatively few population in area and the massive size of these animals, so it is unreasonable to consider that the hunting was the reason for the extinction of these animals.

Second, the reading suggests that the ecological change in the climate maybe the reason for the extinction of the see cows. The lecturer, on the other hand, rebuts this suggestion by saying that if the extinction was due to the climate change, it should have affected other animals like the whales which lived at the same time, but there is no evidence that supports this hypnosis.

Third, the reading mentions another possible reason which is the trading of the fur by European who came to the island, so they started over hunting these animals for the sake of its fur. The lecturer contends this claim by stating the arrival of those traders actually happened when the numbers of the sea cows had already decreased. In other words, the extinction started before the arriving of the European fur traders.

Finally, we can conclude that the exact reason for the extinction of the sea cows is uncertain or unknown until now. It is unlikely to be any of the reasons mentioned in the reading.
