Another Way to See
If you have Google Earth installed on your PC, you may be interested in the re-launch of Another Chance to See, a blog inspired by the Douglas Adams book, Last Chance to See, about the late author's worldwide adventure in search of some of the planet's most endangered species. Gareth Suddes, the brains behind the blog, has posted a kmz file featuring the places on the map where Adams and biologist Mark Cawardine went on their journey.
Google Earth was an exhibitor at last year's Sierra Summit and the product has since been put to effective use by the Club and other environmental groups in campaigns where good maps are crucial for grasping the issues.
While you're in Google Earth (it's a free download, by the by), be sure to switch on the National Geographic tab under "Layers" and check out the geo-positioned photos from biologist Mike Fay's "megaflyover" of the African continent.
