Yes. Moais aren't eternal. It is known that their level has decreased from 15 to 20 centimeters due to erosion caused by wind, water, sun and the action of men and animals.

In 1981 an expert in monuments conservation from UNESCO studied and defined the treatment for moais. The procedure consist in drying the statue, isolating it from rain, to remove all microorganisms like fungus, lichen and algaes and to add a chemical 10 cms deep to avoid physical damage due hits. After that an impermeable solution should be added to avoid water from entering inside.

When were the Easter Island Heads made?

Easter Island Heads have been examined for decades and yet no answer can be given to the mystery as to why they were made. Thor Heyerdahl spent several months there and wrote of his experiences in Aku-Aku. The statues were made on the island and partially complete ones can be found in a quarry. The natives also demonstrated a method that could be used to move them and set them into place. I think a long time ago, the people of Aku-Aku built the statues to scare away some of the other countries. Or, they could have some religious significance.
