Since students spend more time at school than anywhere else, at least six hours a day, school is the best place to educate them a “green” lifestyle. How can we have a green future without green schools? By going green at schools in practice and the classroom, we can bring about the idea that such sustainable lifestyle is normal and acceptable. That will make the process of producing new generations of responsible people much easier. We would like our students to think about their environment and ways, how to improve it.
