I think it's important to note that that contemporary language death at the hands of the major lingua francas (you know who you are) is wiping out great and possibly very old works of oral 'literature'. Quite a few of our surviving great epics, sagas, and lyric(s) originated as oral works. With the death of collapse of these languages, from the Amazon to Siberia to Africa to Europe, these works (not to mention the loads of historical and cultural revealed in them) have or will shortly go entirely extinct.

Not too much we can do about it though.
