Photo taken on Aug. 5, 2018 shows the Rhone Glacier covered with white blankets near the Furka Pass in Switzerland. The Rhone Glacier is protected by special white blankets to prevent it from further melting as a result of global warming. Dec. 11 is the International Mountain Day, which was established by the UN General Assembly in 2003 to encourage sustainable development in mountains. "#MountainsMatter" is the theme chosen for this year's celebration of International Mountain Day. (Xinhua/Xu Jinquan)
