The Alps have been hurt by growing tourism and a migration of people from lower levels into more mountainous terrain. The Himalayas are being harmed by war, deforestation, drought, logging and overgrazing.
Other ranges under stress were:
the Rockies and Coast ranges of western North America, due to increasing pressure from recreational activities such as skiing and home-building in prime mountain land.
Great Smokey Mountains in the eastern United States, due to air pollution.
Amber Mountains in Madagascar, where 80 percent of forests have been lost to farming, mining and charcoal production.
Snowy Mountains of Australia, where 250 plant species were threatened by a series of warm winters.
Western Carpathians/Tatra Mountains in the Slovak Republic and Poland, impacted by air pollution and growth of tourism from surrounding urban areas.
Sierra Chincua in Mexico, winter home of the monarch butterfly. Forest is being lost to logging and farming.
Pamir mountains in Tajikistan. Civil war has resulted in widespread devastation and poverty.
Hengduan mountains in southwest China. A ban on logging and a push to develop tourism threaten mountain cultures.
