winning, sometimes losing. Living thus, with their destinies determined by the sea, has forged a fellowship, a unique coastal culture across national frontiers. Future climate changes will, however, threaten both this fellowship and the Wadden Sea itself. The Wadden Sea has the world’s most expansive tidal flats and therefore vital for millions of migratory birds. Today the Wadden Sea is inscribed on UNESCO’s World Heritage list of irreplaceable world natural assets. THE WADDEN SEA – nature and cultural heritage written by experts from all three countries, is broadly accessible and richly illustrated. The book addresses both readers with a professional interest and all those wishing to learn more about the remarkable and fascinating world.
