Szukana fraza: [Abstract = "In the countryside, several surface mines were opened that initiated the most tremendous landscape changes. Lignite surface mining was the industrial sector that caused \- and is causing to this day \? the most comprehensive landscape destruction, generally in some distance from existing towns. In the course of these processes, thousands of workers moved into the industrial centers. In Lower Lusatia, the population increased considerably in the town Cottbus as well as in the two districts of Calau and Spremberg, where lignite mining expanded in a particularly intensive way."]
