But the water supply is in peril. El Alto and its sister city of La Paz, the world's highest capital, depend on glaciers for at least a third of their water — more than any other urban sprawl. And those glaciers are rapidly melting because of global warming.
Informed of the threat, Quispe, a 37-year-old Aymara Indian, shows alarm on her weathered face. "Where are we going to get water? Without water how can we live?"
Scientists predict that all the glaciers in the tropical Andes will disappear by mid-century. The implications are dire not just for La Paz-El Alto but also for Quito, Ecuador, and Bogota, Colombia. More than 11 million people now live in the burgeoning cities, and El Alto alone is expanding at 5 percent a year.
