Every farm has a midden. Be thankful that they always dump the rubbish in exactly the same place. I wouldn't ever align them with the crap-casters, tossing and scattering rubbish with every step.
The Neolithic people on the west coast of Canada have done this as well over 15,000 years. The shell middens (oyster/clam/mussel) contain 10s of thousands of cubic meters of shell.
I wish that was true. When I canoed a local river over two days a couple of years ago the banks were strewn with silage bale plastic. My onw wood has to be regularly 'litter picked' of the same stuff that the farmers just leave lying about and then gets blown everywhere.
No other industry would be allowed to get away with the mess left and dumped in the countryside.
