Easter Island
15
The moai (statues) pictured above are on Easter
Island (Rapa Nui) off the coast of Chile. The
island is famous for its statues, its remoteness,
as well as its ecological collapse. A once
thriving civilization of tens of thousands of
people built, moved, and erected the nearly 100
ton statues without the aid of modern technology.
However, that same civilization consumed too many
resources and left the island treeless, nearly
birdless, and fell into clan warfare and
starvation. The once mighty population dwindled
to less than a couple thousand by the 1700s
