Unscramble the Blue Letters
Now you're told over and over, repeatedly, that desertification is only occurring in arid and semi-arid areas of the world, and that tall grasslands like this one in high rainfall are of no consequence. But if you do not look at gssarldnas but look down into them, you find that most of the soil in that gaarlsnsd that you've just seen is bare and covered with a crust of algae, ldenaig to increased runoff and evaporation. That is the cnaecr of desertification that we do not recognize till its terminal form.
