"Mountains are crucial to life. Whether we live at sea level or the highest elevations, we are connected to mountains and affected by them in more ways than we can imagine. Mountains provide most of the world's freshwater, harbour a rich variety of plants and animals, and are home to one in ten people. Yet, each day, environmental degradation, the consequences of climate change, exploitatative mining, armed conflict, poverty and hunger threaten the extraordinary web of life that the mountains support." (Text taken from the FAO Sustainable Management of Mountains website.) The UN General Assembly designated 11 December as International Mountain Day in 2003. It is "an opportunity to create awareness about the importance of mountains to life, to highlight the opportunities and constraints in mountain development and to build partnerships that will bring positive change to the world's mountains and highlands". You can find out more from the International Mountain Day web pages, which advise on the different themes for each year. Another useful resource is the Mountain Voices website, which presents interviews with over 300 people who live in mountain and highland regions round the world. To find resources to help you celebrate International Mountain Day in your school, have a browse through the resources listed on the Global Dimension database under the topics of Biodiversity, Sustainability or Environment.
