The human footprint on seas and coasts is one of the most severe environmental problems. People’s health is threatened, marine life is degraded, and the aesthetics of the landscape is altered. Our students prove once again that they are active citizens by taking action. Beach clean-up is an easy, fun and valuable process, which, together with sorting the litter, allows children to realize the problem up close. Their involvement in ecological actions is a beacon of hope that guides and inspires us all.
