>>1928136>>1925194There's a whole ecosystem under a rock. One cairn here and there as trail marker is no biggie, but since it has become some kind of social network "thing" people are building loads of them, at a scale that destroys natural habitat, both by suppressing the "under rock" space for critters, and increasing erosion, as the ground isn't protected from the rain, etc... Like anything, the problem is in the scale. Some intervention on the ecosystem is fine, especially if it serves a purpose (fire building, trail marking), but if every passer by starts stacking rocks by the dozen the impact is very real.
It's not some /out/ autismo, it's a very real problem. Wher I live, land conservation and coastal preservation agencies and communicate regularly on the impact on wildlife and you can get fined like for throwing trash or making fire in a no-fire zone. People have been building cairns for millenias, but it has only become a problem since attention seeking retards have started building them for internet points.
