Hiking.. have you actually hiked anywhere in else in the world? Most places you can fill a garbage bag in an hour just walking on a trail. Took my climbing friends from Canada on a long Hike in Kita Alps, they brought a garbage bag as they always do to gather other peoples trash. We managed to find 2 empty water bottles in 3 days having covered close to 50km. See the campsites near huts after people leave in the morning they are EMPTY.
Try camping at a car camp sites.. now compare that to the clusterfuck of drunks, blaring music, trash, puke piss, shit that you get in NA. Went to Ishikawa for a week this summer camped by the sea, huge camp site tons of people actually very nice. Same thing in US? God fucking help you. This is why they actually don’t have assigned lots for tents, in Canada people would get killed every long weekend if anyone was dumb to try that(car camping)
Of course there is garbage in cities in some places but compared to vast majority of the world it is clean. They actually clean public toilets.. it is a miracle.
