The Puna region, on which this book focuses on, spreads on part of the northern territories of Chile and Bolivia, on the southern part of Peru and on the north-eastern Argentinian territories. This region, impossible to describe with words, is part of an intact, untouched world, that often reminded me of the landscape pictures of Planet Mars sent by NASA in January 2004. The analogies are several, especially as far as the scenery is concerned: the landscape is scattered with dunes, craters and saltwater deposits. The Puna is also one of the few existing intact ecosystems in the whole world, enclosed in an upland located at almost 3500 meters (12.000 feet) on the sea level. These photos wish to give back an identity to those who still believe in the values and importance of nature and therefore maintain a respectful relationship with the Earth.
