By implementing the exchange project, the youth wanted to determine together whether the regions they live in have an impact on personality development, perception of the environment, physical condition, and conditions of ethnic and social groups. Mountains versus sea. Young people wanted to compare the cultural, living, natural and atmospheric conditions of the regions. Check what makes some people feel better in the mountains than at the seaside and vice versa? They wanted to find the pros and cons of everyday life in the mountains and by the sea. Check how our geographical location and climatic conditions affect us. We often hear that traveling broadens our horizons, changes our point of view and thinking, so it's worth checking it out. The youth wanted to check issues they did not understand regarding nature, cli-mate, terrain and weather conditions. The main goal of the project was to actively develop young people's competences in supporting a sustainable en-vironment. Understanding the principles that govern the natural world. Rais-ing awareness of important social issues. The specific goals were aimed at learning about the natural environments of our regions (Kretingos and Pieniny) and learning about the culture of these regions. Activities under the project were intended to contribute to sensitizing young people to the needs of the natural environment and finding ways to protect it. Learning more about the nature and culture of our regions was intended to enable un-derstanding the needs of local communities and the needs related to the nat-ural environment. The exchange was also intended to contribute to under-standing responsibility for the natural environment, understanding the im-pact of science, technological development and general human activity on the natural world. Finding answers to the questions: how to preserve the beauty of nature for future generations? How to contribute to the implementation of pro-ecological activities in the local environment?
