Mountains | Martin Price

Mountains cover a quarter of the Earth's land surface and are home to about 12 percent of the global population. They are the sources of all the world's major rivers, affect regional weather patterns, provide centres of biological and cultural diversity, hold deposits of minerals, and provide both active and contemplative recreation. Yet mountains are also significantly affected by climate change; as melting and retreating glaciers show. Given the manifold goods and services which mountains provide to the world, such changes are of global importance.
