On the slightly larger side, I was able to visit Easter Island at one point. Depletion of natural resources led to an all out class war that nearly wiped everyone out (see: the popular 'Collapse' (2005)). It is a very eerie place to visit because there is not much vegetation across large parts of the island and you can see the the extent of the island in all directions standing on one of the peaks. I couldn't really put my finger on it at the time but I definitely had an uneasy feeling being in such a remote location in the middle of the vast ocean. It hits you in the gut that you would be trapped on this tiny speck of land if it were not for the occasional airplane or cargo ship. I can only imagine what crew of the Bounty (or any other shipwreck) felt.
