Not without human interference. But my point is homo sapiens and ancestors/relatives have been doing stuff like ‘stack rocks’ for well over two hundred thousand years, quite plausibly two million plus years, that is basically nature.
I struggle to believe there’s evidence that moving some rocks has any non-negligible effect on local populations or biodiversity. Life is very, very, rarely as fragile as you describe. But please share if there is indeed such evidence and I’ll change me mind.
Aye, well there are two aspects here - one, thanks for the evidence, that’s cool, I concede the point. And two, this is clearly an american phenomenon that is much more prevalent than I ever would’ve imagined.
So given the context and info, I very much concede my point and appreciate the educating, thank you!
