"There is no justification for this behaviour." A national park in south Wales said it has noticed a "change in attitude" among visitors to its beauty spots, leading to an increase in litter dumping. Human poo, food covered in maggots and a tent "full of kit" were among the items left behind at Bannau Brycheiniog National Park. The Countryside Code states that "dropping litter and dumping rubbish are criminal offences".
