A view of the Huayna Potosi glacier in the Bolivian highlands, some 30 km (19 miles) from La Paz, November 7, 2009. From the Himalayas to the Andes, faster-melting glaciers spell long-term risks for hydroelectric power and drinking water. A lack of water for hydropower is already "critical" in Bolivia, Peru, Colombia and Ecuador, according to the U.N.'s Intergovernmental Panel on Climate Change. Over 2 million people in the La Paz region depend heavily on the glacier on Bolivia's Chacaltaya mountain and neighboring glaciers for tap water and, indirectly, for electricity supplies.
