2 page anthropology paper

As the Easter Island audios have discussed, the most hotly debated topic are the causes underlying the collapse of the Rapa Nui.   There are primarily two opposing camps: environmental mismanagement (internal) vs. western imperialism (external).  I want you to conduct some research and prepare a 2-page write-up on the evidence you were able to find and then tell me what YOUR perspective is!  Do you think one argument is more probable than another?  I am open to any and all perspectives.  Have fun!
