The idea of writing the project "Walk Light" came to us since we felt the need of sharing and discussing with young people from all over Europe about topics such as "environment and climate change", "natural science" and "health and wellbeing". Starting from this topics we want to develop and improve the relationship between man and nature, in order to respect more nature and ourself, and to have a better and healthier lifestyle. The Project will take place from the 8th to the 16th of August 2015, at the Casa Laboratorio "Il Cerquosino", on the Monte Peglia, nearby the city of Orvieto (TR) and it will involve 28 participants from Hungary, Finland, Greece and Portugal and Italy. The activities will be mostly in contact with nature, this means outdoor activities, the methods used will be those typical of non formal education. Our objectives are to promote behaviours of respect of nature and the self, and to amplify knoweledges of natural sciences. We expect each partecipant to be engaged in finding possibilities to share what aquired during the project in his local community, workshops will be made, in order to find a common way of acting once back home.
