There was lots of variety in my weekly walk down the Ravensbourne in Deptford’s Brookmill Park - in addition to the black bag of litter collected - mainly cheap lager cans, a dumped shopping trolley was reported via LoveCleanStreets for Tesco to collect from the river - it made a change from dumped Lime Bikes. I also had time to pull out a massive clump of the very invasive, river bank destroying Himalayan Balsam, probably around 50 plants.
