Nowadays, children are faced with the concept of climate change from a young age. As they grow up, they get information about it mainly through the media, and later through the education system. However, this topic is often too abstract for them and leaves the impression that it happens "somewhere else" and to "someone else". However, we are witnessing the appearance of an increasing number of children and young people who are very loudly warning about this problem and who can be and are the initiators of change among their peers. Peer learning, in an informal and fun way, was the point of this youth exchange. The main goal of the "Acta, non Verba" project was to raise the awareness of young people about the negative effects of climate change on all aspects of life and encourage them to act. The specific goals of this project were: 1. acquiring new knowledge and skills related to climate change, but also the fight against it; 2. promoting positive attitudes and habits to preserve the climate and environment; 3. empowering young people with fewer opportunities for local action in the fight against climate change
