Youth Exchange 90 km for Planet Earth was created with a goal to promote public awareness of sustainable development and educate young people about their impact on the environment and their options for making more sustainable choices. Within 11 days 26 participants from Macedonia, Serbia, Poland, Romania and Germany will hike 90km distance in Galicica National Park and in shores of Lake Ohrid - the oldest lake in the Europe with surroundings of high natural, historic and cultural importance. Idea that lies in the heart of this project is that economic progress must not compromise the key assets of humanity - the quality of the environment and landscapes, human rights and social equity, cultural diversity and democracy. In guidance of experts young people will learn about unique species in area, about processes that are endangering the nature, as well as discuss, how we can change our own habits and mindsets in order to reduce and minimize damage that we are doing to our planet. Outdoor activities will be combined with interactive workshops about sustainable development and creative thinking and animation workshops - final product of the project will be series of short animations in languages of all participants and in English that aim to increase public awareness of importance and principles of sustainable development and promote environment care. Created material and results of the workshops will be presented to local inhabitants living in towns and villages around the Lake Ohrid and used in further work of all involved organizations.
