TPO 34
The reading specifies that there are three theories about the main cause of the extinction of the sea cow. However, the professor explains that we cannot find out what make sea cows extinct and presents some evidence to refute them all.
First of all, the author states that sea cows were a good source of food and native siberian people hunted sea cows for many years and after a while they become extinct. The professor opposes this point by saying that the sea cows were massive creature and weight ten ton and capturing couple of them could feed many people for a month. Also the population of native siberian were few and it was not vital for them to capture large number of sea cows.
Second, based on the reading, there was ecosystems disturbances which declined the main source of food of sea cows and these change help its extinction. The lecturer assert that if sever ecosystems disturbances happen and decline the main food of sea cow, it also change the population of other marine animal and not just kelp and native people do not record any food shortage and it is not feasible that because of the ecological changes sea cows extinct.
Third, according to the reading, when European fur traders come to the island, they had many weapons that allow them to capture and kill sea cows and because of this sea cows extinct. The speaker contradicts the idea reasoning that the population of sea cows decreases before European fur traders come to the island. Hence, it was another main reason that trigger the reduce of sea cows population and European fur traders did not have a role diminish of sea cows population.
