During the fine weather at the end of June all the Coomons, including Wandsworth Common, have been invaded by sunseekers – often picnicking and leaving vast amounts of rubbish. The Friends of Wandsworth Common and those paid to empty bins have made a sterling effort to clean up but the littering shouldn’t be happening in the first place.
38 Degrees have set up a petition and you can add your name to that in the hope of effecting some important drivers including fining perpatrators to reduce the problem:
