Mountains have an extremely important role in influencing global and regional climates and weather conditions. They cover around one-quarter of the earth's land surface and are home to 720 million people around the world. Indirectly, billions more living downstream also benefit from mountains.
Mountains provide us with freshwater, energy, food, biodiversity, and medicinal products – resources that may become very rare in the coming decades.
