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.

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.
