When climate changes, nature feels it. Mountain areas are particularly sensitive, and the greatest losses in terms of plant and animal species may occur precisely there. According to scientific estimates, almost every second plant species in the Alps is threatened with extinc-tion by 2100. For the flora with the highest number of varieties in Central Europe this would be an enormous loss. Because of global warming, also well-known animal species such as the Alpine ibex, the snow grouse and the mountain hare will experience far worse living con-ditions in the Alps.
