The Baltic Sea and the land around it – a young sea in an ancient cradle – were shaped in an interaction between colossal forces of nature. All the stages in this dramatic process played a part in creating the features and characteristics we can see today: the nature and ecosystems of the Baltic Sea region. Changes and trans formations have taken place over thousands, millions, indeed billions, of years, and formed special, in some cases globally unique, forma tions and living environments to enjoy, cherish and protect.
