I see a fair amount of this. It is all about culture. A lot of this problem is from illegals who have no concept of picking up trash.
Why should that worry about it? It is not their country.
Another group is urban “utes”. They do not see anyone else around, so they figure it is ok to trash the place.
I also see a lot of gun culture people regularly haul away truckloads of trash on their own.
It is common for gun clubs to do this.
“that worry” should be “they worry”
