the decrease in native Eastern Island population for three main reasons:
deforestation
rats
a fight between long-eared and short-eared people.
The article states that Eastern Island civilization had been destroyed and provides three main reasons of support. However, the professor explains that there are some flaws in these ideas and refutes each of the author's reasons. In the following, the statements of the lecturer will be discussed.
First, the reading claims that there was a huge deforestation due to cutting down massive forests which led to tremendous erosion and extinction of the native citizens. The professor refutes this point by saying that the natives tried to replace cut trees with grass. He states that this action hindered the process of erosion.
Second, the article posits that rats consumed almost all nutrients in that location. On the other hand, even though the professor agrees that rats are harmful for the eco-system, the natives used this animals as their food. According to the professor's statement, bones of rats, as well as chickens, were found in the place which proves this idea.
Third, the essay concedes that, a deadly battle between short-eared and long-eared people decreased their population enormously, but the professor opposes this idea by explaining that the war was one year earlier that that massive decrease in their population. Accordingly, he states that the fight of immigration of Spanish people from Peru (with about 3000 people) which led to pershiment of two-third of the population was in 1681 one year after the great war.
In conclusion, as the lecturer claims, the answer to this convoluted mistery is still vague owing to the fact that none of the abovementioned ideas are not solid proofs of the disappearance of the native population.
