Along the central Andes mountains, 4000 m above sea level, sits a 1000 km wide plateau. Here, air is thin, water is scarce, temperatures swing wildly from night to day. But even here life has found surprising ways to survive. Against a dramatic backdrop of super-heated geysers, arid grasslands and snow-capped volcanos, animals like the vicuna, the flamingo, the viscacha, the giant hummingbird, adapt and thrive in this life of extremes.
