No group or other entity decimated Easter Island. The damage to the environment cannot be estimated in tenths and surely 1/10 damage is not nearly so severe as to warrant all the speculation. Decimation refers specifically to the killing of 1/10 of a group of people. It has been done since Roman times(Latin is the origin of the word) as reprisal for resistance by non-assimilatted populations or it has been done as punishment for losing a battle right up to Soviet times.
Ooooook. See blam? Should have left original title in tact, like i did, when i posted the article without checking whether someone else had already posted it.
You know that nobody cares about the content of the articles, its the "TYPOS" and "WORDCHOICE" that they critisize. Just like laywers.
