The author of the reading and the lecturer both present the underlying reasons the extinction of a mammal known as Stellar's seacow lived around Bering Island off the coast of Siberia. The reading states three possible main couses. Overhunting seacows by group of Siberian people, ecosystem disturbance and the Europian fur traders kill them with weapons. Nevertheless, the lecturer says we do not know the main causes and stays opposite of these three main causes.
First, the reading states that seacows were overhunted by groups of Siberians at that time. The reason is Siberians had wuite large population and they need to hunt many of seacows for living. However, the lecturer says seacows are massive animals with their 9 meter long body and 10 tons of weight. Siberian people was not that large that they would need to hunt a lot of them.
Second, the reading claims that there was ecosystem disturbances because of that Siberians had a decline in their main source of food. In contrast, the lecturer says is something happened in ecosystem that would not be for killing them. There were also other marine animals and there is no report of hunting other animals. Because the animals gwowing well at that time, ecosystem disturbance can not be the main cause of killing seacows.
Third, the reading believes that after 1941, many Europian fur traders came to the island and they killed large number of animals with weapons. However, the lecturer says the population of seacows were already quite small hundred of years before the Europians came. Whatever the main cause, it is not because of the Europian traders.
In conclusion, the reading claims three reasons why seacows in Siberia became extinct. However, the lecturer claims those reasons that reading accept at least one of them, can not be the main causes.
