And the captain isn't kidding about the bleeding to death thing. I remember the phrase 'soil erosion' popping up a distressing number of times in Jared Diamond's ''Collapse'' (usually in reference to something like the Mayan collapse, or the Fertile Crescent becoming unfertile, or Australia's environment...) and other places. It's still a little odd in America though - I personally associate yellow effluvium with more China and the Yellow River and company.
