I one asked my Earth Science teacher why there aren’t huge craters at the base of every tree. You know, since trees use up the soil to create trunk, limbs, leaves, etc. He looked me like I was stupid. All that mass is actually taken from carbon in the air. The same is true of sod.

That said, I do think they lose a bit of dirt every time they harvest sod.
