Vad är särskilt med vattnet i Östersjön?
What is special about the water in the Baltic Sea?
Correct answer: It is brackish water
Brackish water is less salty than the oceans. Many rivers flow into the Baltic Sea and the exchange with the Atlantic is small. The sea is therefore sensitive to eutrophication, and Sweden cooperates with its neighbours to protect it.
