Jared Diamond: Five Reasons Why Societies Collapse

In groups of 4, investigate why these societies collapsed.  Each group picks only one society.  You may use the link offered as a starting point and must find at least one more.  Read and research the reasons cited for their collapse and in the column to the right, using key words, indicate why that society disappeared.  The fuller explanation will be on a Google document belonging to the group's members.  Compare what you have learned with the 5 point system that Jared Diamond uses to understand societal collapse.  

As a culminating activity, with your group, make a Google presentation of approximately 5 slides that outline your research sources, the reasons for this social collapse and of course, some images.
