Some 1,000 years ago, a small band of Polynesians sailed thousands of miles across the Pacific to settle one of the world’s most isolated places — a small, previously uninhabited island they named Rapa Nui. Eventually, their numbers ballooned to unsustainable levels, they wrecked the environment, and their civilization collapsed. At least that is the longtime story, told in academic studies and popular books. A new study challenges this narrative of ‘ecocide’ saying that Rapa Nui’s population never spiraled to unsustainable levels.
