Agree with you re fag ends, litter, etc. unsightly. Even walking along the canal-bank in a remote location in Co.Kildare, you'd come across all kinds of litter - cans, cartons, takeaways, bottles, plastic bags - left behind by youngsters shopping at the local Mace/Londis/takeaway, sharing the car and driving out to quiet places to mess about.
One thing that strikes me - where do those types of litter originate? The local shops and takeaways, of course. If I'd be in control of the country, I'd insist on legislation where consumables (beverages, sweets, snacks, etc.) are sold - to be sold on the 'loose' (can't think of correct word). Those wishing to buy crisps, drinks, takeaways, would have to bring their own mug/bowl/dish (plastic, of course) of standard size - to be offered free by the manufacturers of beverages/snacks. That would cut out disposable bags, cartons, cans.
What do you think? Up to the 1960s, kids would buy 'pop' in glass bottles and return 'empties' in exchange of pennies. There need to some kind of incentive to discourage careless disposal of empty cans/cartons.
