[terramars]

this is a terrible title. what the article says is, a third of the corn belt has lost all of its topsoil. the rest of it has lost a large percentage of it (some of which may just have migrated). so the situation is actually quite a bit worse than the top line. of course the good thing is all of that is repairable, the bad thing is it will take centuries to fully restore the grassland if you leave it alone - which of course can't happen!
