My take on your question, and it is a personal view formed from experiences probably not shared by othrs. People treat a place with contempt when they are still not sure it is really theirs. You will see this illustrated even in poor places where people are confident of their common ownership- they keep the place pristine even without municipal authorities etc. A state of affairs that contrasts sharply with inner cities where almost everyone is a transient.
Interesting, in the light of the fact that the inhabitants of the North of Cyprus take no better care or no more pride in the place than they do in the South. The roads are littered, there is fly tipping everywhere.
I've wondered about it often on both sides. I came to the conclusion that the 'sight of it' just doesn't bother the locals as much as it bothers those who come from where it would not be tolerated? That they are 'used to' just chucking their rubbish down wherever they happen to be at the time.
In the same way that it doesn't seem to bother Cypriots that they cannot flush shitty toilet paper down the loo because they have never been able to? They are used, all their lives, to seeing bins full of soiled loo paper. And they laugh at those who are horrified at it as if, in some way, they are 'wimps'? They NEVER answer the question as to why it is not a priority in Cyprus to address the problem.
