In its latest foray into the wilderness, Google teamed up with environmental protection group Amazonas Sustainable Foundation, or FAS, to explore a remote part of an Amazon rainforest. Google lent FAS its Trekker device, a camera mounted on an apparatus originally designed to be carried like a backpack by hikers walking on trails. FAS, though, sent the Trekker down a zip line. Google is renowned for going out on a technological limb, but even this project made the company nervous at first, said Karin Tuxen-Bettman, who oversees Google's Street View partnerships. The setup required FAS workers to tread through the rainforest to find a place where they could string the zip line so the Trekker wouldn't bump into tree trunks and branches as it zoomed through the thick canopy. With the help of some monkeys who joined their scouting expedition, FAS workers found just enough room to erect a zip line for the Trekker's trip. Privacy issues shouldn't be an issue in any of the photography taken by the zip-lining Trekker. Birds and insects are the only visible forms of life in the pictures it took.
