The latest Scandi trend is”plogging”: a green version of your daily workout in the local park. Ploggers get their trainers on and go for a run, while scouring the area for detritus to be disposed of.

People who combine picking up rubbish with jogging have been posting their exploits on social media, sharing images of themselves with full-to-the-brim refuse bags at the end of a run.

Seizing the current appetite for ethical living, plogging is urging their followers to "save our oceans, our Earth - one plastic bag at a time!” while having an effective workout with a clean conscience and a lot of fun with friends.
