Same here in the USA. People just toss crap everywhere.
A couple weeks ago I was out on a remote, old mining trail about 25 miles from the nearest road (4X4 conditions the whole way) and found an old refrigerator, a couple of couches and chairs, a table and probably 30 large plastic bags of trash dumped off a low cliff. It would have take a large truck or trailer, 3+ hours each way and probably $40-$50 worth of gas (could have taken it to the city waste landfill for a $5 fee and 30 minutes of time).
My biggest gripe is people throwing lit cigarettes butts out of their cars. Hardly a week goes by there isn’t a fire somewhere in New Mexico caused by that. Fortunately most are spotted quickly and controlled, but last summer one burned about 6000 acres of grassland.
