Winter sport activities and their effect on the environment Franziska Julius Lennart Agnes Ari Isabelle Lavinia

Artificial snow? But why? Artificial snow is small particles of ice It is produced by a machine The first commercially successful machines were developed in the 1950s.

The water is mixed with compressed air and pumped through a high powered fan. The fan can spray the mixture into the air. At this point the snow may be analyzed.

Fake snow Real snow

Rules Do not try to make the season longer by using artificial snow. Only between 15th of November and the 15th of March. Water : +2 degrees ; Outside temperature : -4 degrees. You must not use bacteria

Too many people Much more resources needed Climate change Less snow More fake snow

Too much water and energy is needed.

If you go on ski slopes in summer time, you can see how much damage is caused by skiing.

Resource conflicts in mountains Natural resources are always limited Conflicts occur between traditional primary activities such as farming and developing economic activities that have a less environmentally sustainable approach towards natural resources. The demands of the tourism industry for water and snow are increasing Simultaneously the climate change leads to less available water and natural snow The most water is needed in times of minimal discharge  Rivers dry out  Consequences for the wildlife habitat
