The idea for the project was suggested by young people, it was the result of other already completed projects about which young people informed their friends or information about such events circulated on the Internet. At OHP, we work with disadvantaged youth who do not have the opportunity to participate in such projects in other organizations. We have recently implemented several projects, including ecological ones, and the participants of these projects disseminated their results and shared their knowledge and impressions among themselves, which is why participants from other groups approached the staff asking for help in organizing such a meeting with young people from abroad. The beginnings were difficult, but young people like our methods and activities. On a daily basis, OHP staff work with difficult youth, and appeals not to waste water do not reach young people. Dialogue in this area does not work at school, so peer education is a good idea for dealing with this topic. The preparation of the topic and design work itself have a positive impact on the participants involved. The project aimed to learn about people's bad behavior related to energy, water and garbage, and what are the consequences of such attitudes. We wanted to draw attention to the benefits of living in harmony with nature, with a positive attitude towards the environment and, most importantly, a change in the approach to nature, the environment and consumption. We wanted to share the results obtained with our surroundings. We wanted participants to consciously change their behavior towards water, energy and waste by participating in the project. We assumed that the project would teach us how to work in an international, culturally diverse group, tolerance towards others, and understanding other people and their behavior. We assumed that participants would learn about the importance of nature in everyday life, the consequences of environmental destruction, and many examples of people's impact on the environment.
