"It is extremely important to educate our children about living together with nature. The future of our planet is in the hands of today's youth. Not only keeping the environment clean for ourselves and around us but thinking about the whole planet. Five schools from Estonia, Spain, Italy, Turkey and Bulgaria have come together in order to collaborate and educate children and communities and promote green lifestyle in Erasmus project ""Save the Planet Recycle All"" or SERA, which in Turkish language means ""greenhouse gas"". All participating schools have been already actively practicing green lifestyle, they have put a lot of effort in educating kids and the whole community in environmental issues. Through this project we revised the practises already in use and by taking notes from other countries and schools, tried to enrich the understanding of green lifestyle and how to follow it. Our main objectives were: 1. To give children and teachers a clear picture what is going on in the environment, what are the key issues we have to pay attention to and how to organize our lives so that we can really make a difference in saving the planet from ecological disaster. 2. To form a best possible plan of action for the children themselves to implement in their journey of living sustainable life. 3. To discuss and become aware of sustainable lifestyle and how to achieve it. These objectives were achieved through active collaboration between partner schools and communities and also inside the school community and among children themselves. All actively involved participants showed great interest in the topic, had a lot of good ideas and helped to introduce the importance of green and sustainable life to the whole school and the school community."
