Open cast mine

The video discusses the severe environmental degradation in Eastern Europe's Black Triangle, focusing on the impact of opencast mines and power stations in Northern Bohemia. These facilities contribute significantly to pollution, emitting high levels of sulphur dioxide. The resulting air pollution has devastated local vegetation, with 70% of Czechoslovakia's forests either dead or damaged. Additionally, chemical dumps near the German border have been a persistent issue since the early 20th century.
