So is that relevant because it means that cutting down all the trees want their fault, or because it provides an alternate explanation for what mechanism is causing the soil to else?
And obviously the connection to Denmark is meant to be that a lack of trees causes problems so replacing things with trees must be good. Even if there hasn't been news about those problems happening there.
Denmark has had massive erosion problems for decades to the point there used to be signs about it when I used to go there as a kid in the 1980's.
