Male and female alpacas mate at a breeding farm in Peru's remote southern Andes in the village of Nunoa, February 4, 2005. The wool from alpacas, which is part of the camel family, is used to make fine, high-quality clothing, of which Peru is the world's largest producer. Alpacas are threatened by the illicit trade in animals to Bolivia, Chile and the United States that is depleting their genetic stock and reducing the quality of the wool. But the Peruvian government is funding projects to prevent contraband by implanting microchips in the alpacas to identify them better and track them, preventing them from being sold illegally.( Reuters)
