 :I came here to comment on the exact same thing. For example, this part is verbatim: ""These communities are under some stress, however, as the climate was wetter until the 1930s, with same hot and dry conditions that provoked the Dust Bowl affecting the local climate. These cycles were nothing new, but the original vegetation did not prosper when wetter cycles returned."" And a blog cannot be used as a reliable reference in any case, so the copied content should probably simply be deleted.   "
