The main challenge of the 21st century is to live together and in harmony with our environment since on our planet the resources and space are limited. To meet this challenge through creative activities, interactive workshops, field activities, meetings with local authorities, presentations and discussions the participants of the youth exchange „Re-collected 2011: Reminding our responsibility – preserving our nature” in Kljuc (Bosnia-Herzegovina), 25th of August - 4th of September 2011 from Italy, FYROM, Greece, Bulgaria, BiH, Croatia and Serbia will argue with ecological themes and develop an own awareness for sustainable development and environmental protection through environmental education and volunteering of youth. The aim is to promote intercultural learning and to support building a common future based on the principles of ecology, peace, solidarity and multiculturalism first of all among the young participants and in our local community. All participations will be involved in the preparation, design, realisation, evaluation and follow up of the project. In this context the participants of the exchange take a central position, because they represent the “voices” which have the chance to discover and to discuss future activities in which young people experience and learn to take control of their own environment. The participants will work in small and mixed working and discussion groups, have debates and presentations in the plenary, realise excursions and other outdoor activities related to the theme like field actions and field researches, official meetings and debates with local representatives, evaluations, common free time and evening activities like the intercultural nights and games evenings. The planned activities will contribute to the strengthening of education for sustainable development, environmental education and the role of volunteering among participants and partners as well as a raised awareness of inhabitants of the communities involved.
