Triangle. Easter Island is famous for its 887 extant monumental statues, called moai, created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park.
Polynesian people settled on Easter Island in the first millennium CE, and created a thriving culture, as evidenced by the moai and other artifacts. However, human activity, the introduction of the Polynesian
rat and overpopulation led to gradual deforestation and extinction of natural resources, which caused the demise of the Rapa Nui civilization. By the time of European arrival in 1722, the island’s population had dropped to 2,000–3,000 from a high of approximately 15,000 just a century earlier. In recent times the island has served as a warning of the cultural and environmental dangers of exploitation. Diseases carried by European sailors andPeruvian slave raiding of the 1860s further reduced the Rapa Nui population, down to 111 in 1877.
