Initiatives Oceanes - Beach-cleaning weekend, Versoix as Swiss venue

The Surfrider Foundation Europe program tackles the marine litter issue through education, citizen science and lobby, and everybody can be part of this initiative. On the coming weekends, Initiatives Oceanes organises beach-cleaning-actions all over the World, except North America, with an emphasis on Europe.
Here the map with action points, where everybody is invited to participate. The only Swiss location mentioned is Versoix/Lake Geneva.
