are enormous stone statues called moai– 288 of which once

What Happened?

• The resource needs of the growing population had outpace the island's capacity to renew itself ecologically. – 1400s the forests had

been entirely cut– rich ground cover eroded

away– springs had dried up– vast flocks of birds

disappeared.

– no logs to build canoes for fishing

– depleted bird and wildlife food sources

– declining crop yields because of the erosion of good soil

– nutritional intake of the people plummeted

Culture Collapse• First famine then

cannibalism• Island could not feed the

chiefs, bureaucrats & priests – triggered a cultural

collapse.• 1700-population dropped

between 1/4 and 1/10th its former number

• Many statues were toppled during “clan wars” of the 1600 and 1700’s.
