Is it the few though?Quite, as I said the few bugger things up for the many.
We used to regularly wild camp up in the Highlands. Never had an issue and we would leave only foot prints.
Now you regularly find brand new pop up tents, sleeping bags and empties all just left. Kids have carried them in and can’t be bothered to carry them out.
In most other places the authorities would jump on you. Forest and countryside rangers have the powers of arrest. Chatting with one of the rangers a few weeks ago. They make reports to the police. Police do nothing.
Around the city suburbs of Aberdeen, there are numerous places where things are fly tipped, stolen, damage done - keep people on the public forests/land/walks and out of agricultural or private land. Similar to the USA.
