The BBC reports that shrinking glaciers have the residents of La Paz worried - Glacier threat to Bolivia capital.
Fears are growing for the future of water supplies in one of Latin America's fastest-growing urban areas - Bolivia's sprawling capital of La Paz and its twin El Alto.
Scientists monitoring the glaciers high in the Andes mountains - a key source of water - say the ice is showing signs of shrinking faster than previously forecast.
Faced with a booming population and a combination of glacial retreat and reduced rainfall, the governor of the La Paz region is even contemplating moving people to other parts of Bolivia.
Water is already in short supply among the poorest communities and has become a cause of tension.
