Human impact on the environment can be seen in the deterioration of the alps.

The degradation of the Alpine environment by human activity begins in the mid-20th century, as a result of the development of modern agriculture, mining, manufacturing, and the touristic sector. This resulted in a decrease in air quality (with cases of valley cities facing impure air for some weeks); water pollution in rivers and lakes; slope erosion caused by ski slopes and roads construction, the around areas were almost completely devoid of vegetation; discharging of chemical waste.
