I  feeling like littering at a World Heritage Site.
I find that odd, why don't you just find a trashcan to throw it in?
Oh, who cares. It's just a banana skin.
I guess you don't see a trash can nearby, buy you shouldn't throw the banana peel into the bush. Do your part to keep the site clean and hold onto the peel until you find a trash can.
But it'll take so long to find a trashcan.
That might be true, but it's still the right thing to do. Doing what you're doing is lazy and really offensive towards the world heritage site.
