The Baltic Sea is environmentally stressed due to its geographical location, being relatively shallow and slow-moving, which allows pollutants to accumulate. Pollution stems from two main sources: point sources like industrial emissions and diffuse sources, primarily agricultural runoff containing fertilizers. Journalists also highlight historical contamination from World War II shipwrecks, chemical weapons buried in the seabed, and plastic pollution from abandoned fishing nets, which threaten marine life. Visitors often perceive pollution through visible algae blooms caused by eutrophication, driven by nitrogen and phosphorus from fertilizers, which can be toxic to organisms and potentially harmful to human health. Beyond visible pollution, chemical contamination requires laboratory testing. Environmental degradation is exacerbated by climate change, leading to oxygen depletion and the direct harm caused by oil spills and pharmaceutical residues affecting fish behavior. Furthermore, there is a lack of scientific data regarding the environmental impact from the Kaliningrad region of Russia. Experts stress the urgent need for action to ensure the sea remains viable for future generations.
