Physical Features Impact A major landform that has contributed to the interaction of humans is the Alpine Region, specifically the Alps Mountains. The impact of so many people caused a downfall of the Alpine environment beginning in the mid-20th century. This has resulted in poor air quality; water pollution in rivers and lakes; a rise in noise pollution; slope erosion caused by the construction of ski slopes and roads; dumping of solid and organic waste; erosion from the breaking of rock, sand, and gravel for construction; and forests weakened by acid rain. Slowly, the unique landscape of the Alps that brought in many travelers is being changed in negative ways. The main river valleys have been converted into concrete transportation ways, in order to accommodate the expanding tourist trade, many villages in the higher lateral valleys have taken on the character of lowland suburbs. Pollution from factories, home heating and motor vehicle exhausts,cause the situation to be aggravated by temperature inversions and weather conditions that often produce little wind. Many of the larger Alpine cities experience severe local air pollution, and some of the valleys can be filled with impure air for weeks at a time.
