Easter Island & Cultural Revolutions & Economics
Unit 1 (Chapter 1 and 2)
Summary of Easter Island
Polynesians arrived around 1200 AD.
There was abundant forest and wide variety of trees.
Population grew and trees were cut for agriculture and structural materials and to move the
huge stone heads
By 1600, all the trees were gone no roots, the land failed to hold water, and the soil washed

Without agriculture, the emergence of many of the traits popularly referred to as
“civilization" would not have been possible (e.g. cities, advanced technology, social
hierarchies, organized warfare.)

The Chinese economy has grown at _____% per year
