The project "Clean environment connects nations" is to be implemented by the students of three partner schools - Polish, Danish and Portuguese. The originator of the project are students and teachers of the John Paul II General Secondary School in Pawłowice. Thanks to this initiative, we want to improve our skills in the field of ecological awareness, be able to act on an international level in using English, and at the same time share knowledge in their own environment and in the European environment. All the schools expressed their interest in developing pro-ecological skills and attitudes of contemporary youth and the local environment, such as European, developing social and cultural competences. Portugal and Denmark face similar ecological problems as Poland
