Approximately 500 years ago, the flourishing society of Easter Island suffered a steep decline in population. Many theories have surfaced explaining how this could have happened to such a thriving culture. Within this small, isolated island in the Pacific Ocean, researchers have uncovered archaeological evidence that clearly indicates one theory for the decimation of the Easter Islanders above all others: invaders.

First, the disappearance of nearly every tree on this Island points to the kind of environmental destruction that could only result from foreign incursions. Researchers discovered that this land now devoid of trees was once covered with palms. Biological evidence indicates an abundance of palm for centuries until about 500 years ago, the time when the population nearly vanished. Only invaders could have brought about that kind of destruction all at once.

Another key piece of support lies in the archeological discovery of spear tips that appeared at around the same time as the near destruction of the Islanders. These spear tips show beyond any doubt that there was conflict and warfare on the island best explained by the onslaught of invaders. In addition to these war implements, skeletons from that time have been examined and show the kind of deformation that results only from combat.

Last, the appearance of a new religion provides more support. Special dating methods used by archeologists determined that "birdman" statues surfaced at the same time as the dramatic shift in population. As history proves time and time again, when an invading force occupies a new territory, it takes with it its customs, culture, and religion. The abandonment of the old religious order for the new "birdman" religion as evidenced by these statues must be understood as the outcome of invasion.

The article states that invader led to decimation of the Easter Islanders and provides three reasons of support. Conversely, the professor states that internal factors were responsible for declining in the Easter Isalnd popluations and he refutes each od the author’s reasons.

First, the reading avers that the dispearance of tress, like plam, could only result from foreign incursions. The professor opposes this point by saying that trees were not destructed by incursions, but by inhabitats. The Easter islanders had a variety of inhabitats and each one liked to show its cultural dominance on the Island by building stone status. Since the status need rollers, so they logged trees. The professor conculdes the hihgly competion among inhabitats led to destroy tress and not by invaders.

Second, the article avers that the archaelogical discovery of spear tips supports the invasion theory. The professor, on the other hand, explains that spear tips were comes from not invaders. The islanders used spear tips to defend themselves,but to attack their fellows. He also explains that during that time, there were limited food resources because tress cut down so they couldn’t build canoes to get their food. And consequently, a civial war started among the islanders.

Third, the reading posits that the appearance of new religion provides more support as the outcome of invaders. However, the professor refutes this point by saying the Easter islander did adopt new religion. As the professor mentioned before, the islander went through difficult time, their resources exhausrted, and sadly, their ffamilies die of starvation. So, people adopted new religion, such as birdsman because their current one was ineefective.
