1) Creation of the Ecological Maturity Survey: The survey was used to assess the ecological attitudes of young people and to make them reflect on their own actions. 2) Conducting a series of mini-interviews: A series of mini-interviews was part of the project and contributed to a deeper understanding of environmental issues and the motivation of young people to act for the environment. 3) Creation of a dictionary of useful words: During the project, participants created a dictionary of useful words, which helped to improve language skills and facilitated communication between participants from different countries. The aim of our project "Green Heart - Let's talk about Environmental Volunteering" was to increase interest and ecological knowledge among young people and motivate them to social activities to improve the condition of the environment. We wanted to develop the key skills and competences necessary for us, young people in adult life, i.e. communication, cooperation, organization and the ability to verify information.
