| Easter Island |
In the southeastern Pacific Ocean, at the southeastern most point of the Polynesian triangle. A UNESCO World Heritage site. In recent times the island has been used as a cautionary tale for the cultural and environmental dangers brought upon by the overexploitation of resources. However, this theory is now being contested by ethnographers and archaeologists alike who argue that the introduction of diseases carried by European colonizers and slave raiding which devastated the population in the 1800s, had a much greater social impact than environmental decline. The name Easter Island was given by the island's first recorded European visitor, the Dutch explorer Jacob Roggeveen, who encountered it on Easter Sunday 1722.
