In this set of material，the reading passage mainly introduces three theories that cause the see cow's extinction. However，in the following lecture，a questionable attitude has been raised. What's worse，the real reasons for their extinction are still unknown and these theories are all have problems.
To begin with，the lecture mentions that Siberian people are unlikely to cause the extinction of sea cows，which fully rejects the content that they have probably overhung the species. According to the lecture，sea cows are massive creatives with nine meters long and over 10 tons in weight，and a couple of them could feed small number of Siberians for months. Since the number of people in the village is small，they might hunt some of them，but they do not have to hunt a lot of them.
In addition，the evidence that the decline of kelp，main food source for sea cow，makes the extinction of the species is problematic. The listening section shows kelp might grow just fine，and sea cows might have not experienced a food shortage. To be more specific，if something really severe happened，it would not only affect sea cows，but also other species，like whales. Since there were no signs of report in the decline of other marine animals，sea cows would not likely to be declining.
Finally，the lecture claims its theory towards European fur traders with alternative perspective. It regards that Europeans are the last to arrive and should be concluded as the main cause of the extinction. According to his theory，by the time European traders came to the island，the population of sea cow was already very small. Based on the showed record，there was a
time that the animal was at its peak in number hundreds of years ago，and there must have been something serious happened or happening that decreased the population of sea cows.

Some people may believe that it is more difficult to educate children today than in the past because of this.

Children are able to use social networking Web site to make friends who can learn together, which makes their parents save much time to superior the children to do assignments. Children with their friends can learn from each other so that they all can make a better acedamic performance. If a child study himself, he will feel lonely and will soon get bored on study.
Children can use cell phones and social networking Web site to study and learn better than before, so it is not a more diffcult task for their parents to educate children today than it was in the past.。
