Climate change in Germany
The Rhineland is historically a heavily industrial and population-dense area which includes the states of North Rhine-Westphalia, Rhineland Palatinate, and Saarland. This region is rich in iron and coal deposits and supports one of Europe's largest coal industries. In the past, sulfuric acid emissions from Rhineland coal plants contributed to acid rain, damaging forests in other regions like Hesse, Thuringia, and Saxony.
Rhenish nationalism
In the postwar reorganization of German states, the Rhineland was divided among the new states of North Rhine–Westphalia, Rhineland–Palatinate and the Saarland, while the exclaved district of Wetzlar became part of Hesse. The districts of Eupen and Malmedy had been incorporated into Belgium in 1925.
