In 1993, Elisabetta Eordegh and Carlo Auriemma set sail aboard the specially designed Barca Pulita (which translates, literally, as "clean boat") to circumnavigate the world in an attempt to chronicle the last unspoiled natural sites on earth via a journey that made as little impact as possible on the earth and sea. A 44-foot ketch, the boat was equipped with state-of-the-art equipment that made the most of "green" technology, from the clean conversion of energy to the use of special non-toxic varnish. To date, the boat has covered 40,000 miles, giving the authors the unique opportunity to document the state of a vast range of natural settings. From the tiny Polynesian island of Anuta, with a human population of 250, to the island of Zabargad in the Egyptian Red Sea, known for its rich marine life, they have traversed the sea to photograph the worlds most spectacular places, presented here in superb color pictures that depict the landscapes, flora, and fauna that make each of these places a precious global resource. The compelling text describes the unique characteristics and species of each location as well as the fascinating earth-friendly technology that made these observations possible.
