Easter Island, located in the Pacific Ocean about 4000 miles from the coast of Chile, is one of the most isolated places in the world. It is best known for the Moai, monolithic statues of human figures carved from volcanic rock and located around the island. While today the Moai are a great source of revenue from tourists who flock to the island, research suggests that their construction actually led to the decline and eventual collapse of the island’s culture.
First of all, evidence suggests that the obsession which the people of Easter Island had with building the Moai led to non-productive use of natural resources, specifically of the island’s forests. The Moai were huge, with some weighing nearly eighty tons. Moving them from the quarries where they were carved to their intended resting spots required the use of wooden tracks equipped with log rollers. The islanders cut down vast amounts of valuable trees for no other purpose that to move the statues across their island.
Moai construction continued for centuries and eventually every single tree on the island was cut down to build the aforementioned tracks. This complete deforestation had disastrous effects on the island. Migratory birds, which had been a big part of the islander’s diet stopped coming to Easter Island. Meanwhile, the fishing industry on the island collapsed because the leaves of the island’s palm trees had been used to construct fishing boats. In addition, soil erosion caused by the lack of trees made it difficult to even grown food.
Finally, the above issues lead to a major population decline. From a high of twenty thousand people at the peak of its civilization, only two thousand people remained when European explorers first reached Easter Island in the eighteenth century. This mass die-off was clearly a result of the food shortage described above. Human remains from the period suggest that the population descended into cannibalism as things got progressively worse over the years.
The lecture talks about the findings from recent research on the Moai, a popular tourist attraction in Easter Island located 4000 miles from Chile. While the passage argues that the construction of Moai led to the collapse of the island’s culture, the speaker explains evidence that suggests otherwise.
First, the humongous Moai statues were not rolled over logs to move them from the place of construction to the place of installation. They were in fact moved by tilting them using a series of ropes with dozens of men wrapping the rope around them at either ends of the ropes and then pulling the Moai statues. This evidence from the recent research contradicts what the author states that they were rolled on logs and tracks made of wood.
Second, the palm seeds excavated from the island suggest that there were rats in abundance on the island. In fact, the first people to visit the island brought back rats as food. Theorists suggest that these rats had a deadly impact on the palm trees - feeding on palm trees leading to the decline in their population and eventually causing extinction of the palm trees. This opposes the author who states that due to prolonged deforestation and soil erosion, the folks on the island could not grow even food and the collapse of the fishing industry due to lack of palm trees whose leaves were used to build fishing boats.
Third, the claim that the population had declined from 20,000 in 400 A.D to 2000 in the eighteenth century sounds faulty. The findings from carbon dating analysis show that the civilisation had only started in 1200 A.D. As a result, it is spurious to believe that the island had a maximum population of 20,000. Furthermore, the evidence suggests that the island cannot support no more than 2000 population which was present when the European explorers visited the island in the eighteenth century. This rebuts the passage which argues deforestation, inability to grow food, and cannibalism lead to the collapse of the island's culture.
