tpo 34 the sea cows' extinction
The material discusses the reasons for sea cows' extinction. While the reading suggests three theories that could explain this extinction, the listening disagrees and mentions that the truth is they do not the main reason for sea cows' extinction and there is a problem with each theory of the reading.
First, the author says that sea cows were extinct because of overhunting by Siberian people. On the other hand, the professor challenges this and states that sea cows were massive, one of them was nine-meter-long and weighed ten tons. Furthermore, the lecturer explains that a couple of sea cows could feed Siberian people for a month. the speaker adds that Siberian's population was not very large, so they did not need to hunt a lot of sea cows. The professor cits that overhunting by Sioberain people is not the reason for sea cows' extinction.
Second, the writer states that sea cows were extinct because of ecosystems disturbances that declined their main source of food, which was kelp. On the contrary, the professor opposes this and contends that if there was an ecosystem disturbance before 1968, so not just kelps might decline. The lecturer explains that other marine, such as whales should be diminished too. The speaker adds that there was no report about the declining of other creatures during this period. The professor concludes that kelp grew fine and sea cows did not have any experience of food shortage.
Third, the reading posits that the arrival of the European fur traders was the main reason for sea cows' extinction. Conversely, the lecturer contradicts this and mentions that sea cows were extinct soon after European arrival. The professor cits that sea cows' population was already quite small a hundred years before European fur traders reached the island. The speaker contends that if sea cows declined long before European fur traders' arrival to the island, they were not the main reason for sea cows extinction.
