Bitter cold devastates alpaca farmers

Fleece sold for only $5 a kilogram and a jacket made of the wool can fetch $5,000

After three days of heavy snowfall and bone-chilling temperatures, Mateo Mullisaca watches as one of his alpacas falls to the ground in agony on his farm almost 5,000 meters high in Peru's Andes.

"Without water and without food, the weak ones die," the 62-year-old shepherd said as the animal takes its final breath with vultures lurking nearby.
