Environment is the mainstream to connect schools. How can we involve youth to acquire and adopt consciousness on the importance of living in healthy environments? Sustainability and waste of nature resources are two ideas our schools want to work out with our students. There are positive achievements at school for the 3Rs (reduce, reuse, recycle). We would like to share good practices in schools. Environment concerns Europeans schools. Let schools get together with youth to share experiences and cooperate to improve the future of our planet .
