My name is Stefan and I participated in the project at Hotel Arena on Popova Shapka. I had a great experience, met new people, and learned a lot about ecology and protecting the environment. What I liked the most were the activities and the positive atmosphere during the project. I think SDG 13 – Climate Action is very important because we need to protect nature for the future. My message to other young people is to join projects like this and always try to learn something new.
