my second example is a famous romantic example is the polynesian society on easter island easter the most remote habitable scrap of land in the world and island twenty three hundred miles west of the coast of chile and near absolutely nothing easter island is famous for its dry can pick stone statues when up to eighty tons a record by polynesians and then gradually all of those statues were eventually pulled their own and broken by the descendants of the very polynesians who were wrecked with them it's now clear that east reuland underwent the struggles society underwent a dramatic collapse that's a huge increase in political complexity and also population numbers as a result of the east raw it was inadvertently chopping down all the trees on the iraq war and that's not a wise thing to do if your society have to depend on wood as with easter islanders but lots of societies make mistakes and that happened to the struggle of those so we struggle society collapsed in an epidemic of civil war that was triggered by this ecological inadvertent ecological devastation couldn't you you suggest
