The main goal of the project was to increase environmental knowledge among young people, also to create opportunities to expand and use already acquired environmental knowledge, to form a pro-environmental attitude which is the result of personal reflections and practical experience. We decided to popularize pro-environmental attitudes together with our peers from Portugal and Romania to raise public awareness of caring for the environment. We wanted to share our knowledge and improve them, as well as learn how our partners care for the environment. Our activity has been implemented on the basis of non-formal education methods, the essence of which is the combination of a concrete action with the conscious reflection of the learner.
