Easter Island Deforestation
Description: The island of Rapa Nui once supported a large community of Polynesians that are best known for the massive statues (moai) pictured below. However when sailors arrived on the island in the 18th century the people were barely hanging on. What is not pictured below are any trees. Deforestation led to the collapse of this culture.
