On a winter night last June, José Antonio Tuki, a 30-year-old artist on Easter Island, sat on Anakena beach and stared at the enormous human statues there – the moai. The statues are from four feet tall to 33 feet tall. Some weigh more than 80 tons. They were carved a long time ago, with stone tools, and then they were
moved up to 11 miles to the beach. Tuki stares at their faces and he feels a connection. ‘This is something that was produced by my ancestors’, he says. ‘How did they do it?’

The first Polynesians arrived at Rapa Nui (Easter Island), probably by canoe, hundreds of years ago. The island is 2,150 miles west of South America and 1,300 miles east of its nearest inhabited neighbour, Pitcairn. Nowadays 12 flights arrive every week from Chile, Peru and Tahiti. In 2011, 50,000 tourists – ten times the
island’s population – flew to Easter Island. Almost all of the jobs on Easter Island depend on tourism. And the tourists go there for only one thing: the moai. People around the world became curious about the statues after the Norwegian adventurer Thor Heyerdahl made Easter Island famous, and there are different theories about how the statues were moved to the beach. Many researchers think the statues were pulled along the ground using ropes and wood. Pulitzer Prize winner Jared Diamond has suggested that many people were needed to build and move the
moai. As a result, the island’s trees were cut down for wood and to create farming land. This open land was
fragile and it was soon eroded by the strong winds, so it was very difficult to grow food. The situation was an early example of an ecological disaster, according to Diamond. On the other hand, archaeologists Terry Hunt of the University of Hawaii and Carl Lipo of California State
University Long Beach have a more positive view of the island’s history. They suggest that the inhabitants actually pioneered a type of sustainable farming – they built thousands of circular stone walls, called manavai, and grew food inside them. And their theory about how the moai were moved is that they were ‘walked’ along using a system of only ropes and a few people.
As José Tuki contemplates these enormous statues, he doesn’t mind that there are no definite answers about the history of his island. ‘I want to know the truth,’ he says, ‘but maybe knowing everything would take its power away’.

Hunt and Lipo‟s theory about the movement of the statues involves using ________.
