One of the reasons they fly rock in to make paths in the peak/Wales/Lakes etc is because by using stone from the location adds hugely to erosion. By making a cairn you are taking rock from where it should be to some where it shouldn't, it also attacts people who don't know where they are to follow blindly a pile of stones that can't possibly tell them where they are, this also causes erosion.
Using this kind of logic, however, much of the current erosion in the lakes is actually the fault of Alfred Wainright and Bob Graham (or at least those who publicise and encourage)
