They also drank very large amounts of sugar cane juice because of the lack of fresh water on the island. The largest animal available to the inhabitants of Easter Island was the common dolphin and this animal was about one third of their diet according to the bones excavated in Anakena Beach. They also ate fish but not as much as other Polynesian islands and this can be due to the fact that the island has a rugged coastline and steep drop offs. For that same reason they ate little amounts of sea urchins and mollusks. They also ate large amounts of rats according to the large amounts of rat bones found by archeologists. Seals were also a part of the diet in Easter Island. Some of the plant foods consumed on the island were palm nuts and malay apples.2.The building of Moai on Easter Island required a lot of food to feed the workers erecting these massive statues. But the statues were not just about carving, it was also transportingand making them stand upright. In addition, building the Ahu’s was also very intense physical labor. It is estimated that building Ahu and Moai increased the food consumptionby about 25% on the island. It should also be taken into consideration that many feats were probably held by chiefs to celebrate the Moai. 3.There were several types of agricultural intensification on Easter Island. The first was pitsthat were lined with stones and were 5 to 8 feet in diameter and 4 feet deep and these were used as composting pits where crops were grown and vegetables fermented. There is also evidence of a diverted stream that was used for irrigation of crops. More evidence of agricultural identification are stone chicken houses that were about 20 feet long. The largest evidence of agricultural intensification on Easter Island were giant boulders used as wind breaks to protect crops from frequent strong winds.
