But as highlighted elsewhere, it's definitely more of a cultural problem than anything. It's always depressing just casually observing the amount of abandoned tents on the way out and the amount of litter either put in the wrong recycling bins or just discarded less than yards from them. And the problems isn't just the cost which could be spent on good causes - £750,000+ [0] but the accidental effect of say a cow eating a tent peg (it's a working farm).
As someone who litter picks and talks to litter picking groups it's definitely a big problem nationwide sadly.
Probably unsurprisngly this always seems to be much worse in the higher traffic areas with the main stages than it is in say the Green or Healing field areas though their might be demographic and contextual reasons for that also. I've not been to any of the other main UK festivals in a long time, e.g. Reading, V Festival etc. but I'm guessing they aren't going to be any better?
