Hey there, my name is Nikola, I am from Austria and i was doing a marine biological internship in Pula, Croatia this summer. On our day off, we cleaned the bay of Valsaline in Pula. Our goal is  to prevent the partys that take place from time to time in that bay since they pollute the bay pretty badly. We were shocked by the amount of trash we found. It was only a small bay and we hope we can stop the partys there. There was mostly glass and little pieces of plastic. Also we had to leave some trash in the sea as it was colonized by some animals or plants and we would have killed them if we took it out of the water.
