The fact that Peristera is an unihabited island and the small bay that the dive against debris was conducted is a common anchorage spot for many leisure boats, and a favorite snorkeling site, contribute to the accumulation of debris and thrash that has been found and collected. In addition there are permanent restrictions on the area for any kind of diving activities as it it declared an archaelogical site, a fact which makes any Clean Up dive more complicate logistically in terms of licencing and conducting it.


The Clean Up dive was organised by Thalassa Foundation, in collaboration with Mom (The Hellenic Society for the Study and Protection of the Monk seal) and Ikion Diving center. A special permission was given for the dive Against Debris on this site which was undertaken with great success.
