Stop Plastics is a local group with international connections that has conducted plastic clean-ups at Sam Smith Park in the past. Donna-Marie Batty, a FOSS member who spread the word at last year's Spring Bird Festival, wrote a piece for this blog last year - "Pernicious and Plentiful: Plastics on Sam Smith Shores".
On Saturday, April 22nd, they will be doing a clean-up at Marie Curtis Park and are looking for volunteers. They are planning another clean-up for Sam Smith in September or October. Look for further details.
