Baltic Sea

The Baltic Sea is a body of water in Northern Europe, bordered by countries like Sweden, Finland, Estonia, Latvia, Lithuania, Poland, Germany, and Russia. It connects to the North Sea through the Kattegat and Skagerrak straits. The sea is known for its unique brackish water, a mix of salt and freshwater, due to rivers flowing into it and limited exchange with the ocean. It's an important area for trade, tourism, and fishing, and is also notable for its environmental challenges, such as pollution and overfishing, affecting its ecosystems and marine life.
