Because of its remote location, only a few species of plants and animals thrived on Easter Island, and the water surrounding it contained very few fish. Nevertheless, beginning with extremely limited resources on an isolated island, the native people achieved a very advanced culture, as evidenced by the gigantic monolithic human figures that line the coasts, as well as by other artifacts. The complete collapse of this civilization is still a mystery, but several theories have been put forward.
One theory suggests that the natives of Easter Island cut down large palm forests to clear land for agricultural purposes, fuel for heating and cooking, construction material for pole and thatch houses, and canoes for transportation. In addition, hundreds of ahu, or large stone monuments, were constructed and moved to the coast on rollers made of tree trunks. Assuming that the trees could regenerate quickly enough to sustain the environment, they continued the deforestation, which, in turn, caused serious erosion.
Another theory presents a very different explanation for the decline in the population. Since there were few predators on the island, and an abundance of food, it is thought that rats may have hidden in the canoes of the earliest settlers. When the native people cut and burned trees, the rats prevented regrowth by eating the fresh shoots before they could grow into large plants. With little food and no wood to build canoes to escape, the people perished.
A third theory contends that the population was decimated by a war between short-eared and long-eared people on the island. According to oral history, a plot by the long-eared people to kill the short-eared people was discovered and the short-eared people struck first, driving the long-eared people to a ditch where they were killed and burned.
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.
