Begun in 2014, the Beach Litter investigation is one of the most important citizen science initiatives on an international level. Along with Legambiente, we will be cleaning a beach in the eastern area and, with the assistance of the Park's scuba guides, the area's sea bottoms: the collected waste will be appropriately registered and catalogued, with the objective of helping to enlarge the beached waste database built by volunteers on a European level. After the experience, participants will enjoy a snack.
