The Earth and the environment call for help but not enough people take it seriously. In our opinion the most of what we can do in favor of environment is to live consciously and green in our communities, in our household. For this reason our exchange - in which 19 young people aged 13-18 from Czech Republic, Estonia, Slovakia and Spain took part - aimed to show the youngsters what is their ecological footprint and how big it is, that with the lifestyle they live how big part of the planet is needed to provide them with food, energy, fuel, etc. Further aim was to make them realize that everybody can do something to protect the environment, to slow down the climate change. We calculated their impact then they could discover during the activities what they can do to help our earth, to reduce their footprint. By encouraging them to do so, we aimed to make them active citizens. The program was a combination of different activities which were connected to the questions of the ecological footprint quiz and in such way they touched 5 topics: housing, meal, transport, shopping, waste. During these activities young people could gain new experiences, acquire new skills, then make new friendships, contact and have an impact on local people and get to know each other’s culture. A lot of different non-formal learning methods were applied: games, workshops, outdoor activities, group work, debate, role-plays, round-table and brainstorming. We paid attention to provide them many possibilities not only to discuss the topic but also to learn a lot of things by doing. We wanted to raise awareness with all the young participants of the project about the environmental protection, ecological footprint that is why a short film was made at the end of the exchange to call upon the people to live green, save our planet. The film was presented on the local activity on 22 August, but there was also a leaflet edited about the comparison of the ecological footprint calculation's results of the participants/countries & the participants' ideas about how to reduce their footprint and posters made by the participants.
