Europe-wide beach-cleaning weekend

Next weekend, the Surfraider Foundation, which is committed to protecting the oceans, will be organizing a Europe-wide beach cleaning action. Meanwhile, other continents are also involved. So far, volunteers have organized action days at 624 coastal locations. Here an overview.
The Foundation also provides instructional material for schools, and the collected waste - several tons per year - is also scientifically recorded. You can sign up for one of the actions or even organize one yourself. See more on the Surfraider website.
