Join Thames21 and the #OneLess Bottle campaign for a huge plastic counting project on the Thames. On the 24th September 2019, we will be sending volunteers to 18 collection hotspots on the Thames to count and remove that rising scourge of the world’s rivers and oceans – plastic drink bottles. Last year, we recorded over 3,400 bottles during the event, between October 2017 and September 2018, over 35,000 bottles were recovered from the tidal Thames.
