The Baltic Sea
The Baltic Sea is a unique, brackish inland sea located in Northern Europe, bordered by several countries including Sweden, Finland, Russia, and Germany. Known for its distinct ecosystem due to its lower salinity compared to oceanic waters, it supports diverse marine life and plays a crucial role in the Baltic region's environment. Historically significant for trade and exploration, the Baltic Sea remains an important area for shipping, fishing, and tourism, while facing ongoing challenges related to its brackish water and sea ecosystem.
