It’s not about the quantity of litter that ploggers collect, but the quality of the urban environment left behind as a consequence of plogging!
Lots of the rubbish that is washed up onto our beaches has been washed out to sea, having been washed down one of these drains. Ploggers represent the barrer at the top of the cliff, as opposed to the Ambulance at the bottom.

Plogging can be done anywhere, at anytime and by anyone!

Rubbish waiting for the rain to come and wash it away. An all too common site in suburban Auckland (so common that many people don’t see it).

Gloves are recommended!
If you don’t have gloves or want to run with a rubbish bag, I find that the bags you put your fruit and vege in at the supermarket are the perfect size for putting into your pocket and picking up bits of paper, cardboard and plastic (but not so good for glass, clothing or metal items). Once full up, you can simply dispose of the contents into a rubbish or recycling bin.

My personal preference is at the end of a run, during my warm down, but i also do it during my walks to/from work. I also always try to do at least one plog when on holiday.

Sadly, I found a lot of litter during my early morning plogs along this road.

If you don’t have a bag handy, just do it when there is a rubbish bin nearby (you don’t have to take it home and recycle it. The point is to get it off the streets.
