The thing is that millions of people will die as a cause to these world changes. Take Japan for example. If you look on the map (I looked at the map up close when my parent's friend showed it to us) Japan is not there. Therefore, all of these disasters taking place in the present are probably forming that future map. That's of course if one believes Scallion's map is accurate. If you look at this whole thing religiously, this world change kind of mirrors the idea of cleansing the world of it's corruption.
