home of 90 million people
The Baltic Sea is the home of 90 million people. Nine coastal countries surround this small and shallow sea. The coastal states are Finland, Sweden, Denmark, Germany, Poland, Lithuania, Latvia, Estonia and Russia. Over 15 million people in these countries live less than 10 kilometers away from the sea. We, the Baltic Sea people, are united by the sea and how it affects our different cultures.
Baltic Sea is not well
Unfortunately the Baltic Sea is not doing well. The sea suffers from eutrophication which drives biodiversity loss. Climate change is exacerbating the Baltic Sea’s problems even further by increasing rainfall and warming and freshening its waters. The poor condition of the Baltic Sea is evident, for example, in blue-green algal blooms and murky water.
PROTECTING THE SEA IS CRUCIAL
To ensure that the Baltic Sea and its species can thrive, we must protect it through effective measures. The sea is vital for numerous species below and above the surface, including fish, birds, plants, and microorganisms. In addition, we must ensure that the Baltic Sea can continue to provide local nature, recreation, livelihoods, travel and transport opportunities, and a future for people.
SUCCESS SHOULD BE CELEBRATED
The Baltic Sea would be in a much poorer condition without the conservation work that has taken place over the decades. Thus, Baltic Sea Day is also a time for celebration. Without these efforts, the sea would be far worse off.
Baltic Sea Day is a day WHEN WE CAN ALL ENJOY THE SEA TOGETHER!
