The Mediterranean has always been at the heart of major upheavals of history because of its geographical position at the crossroads of Europe, Africa, and Asia. At the present time, it epitomizes most of the dangers affecting our planet. In the Mediterranean, every landscape reminds us of the legacy for which we act as guardians. I believe that none of us can ignore this compelling duty that makes us a mere bridge between the generations that have come before us on the shores of this sea and those that will follow us tomorrow. Today, the environmental future of the Mediterranean is threatened by global warming, the alarming erosion of biodiversity, and the reduction of freshwater resources in the region. These phenomena have not yet reached an irreversible stage – therefore effective action can and must be displayed now.
