Fragile Earth? There’s an app for that

See the world change in front of your eyes with the Fragile Earth app for iPad. Essentially, it’s an interactive photo gallery that gives a bird’s-eye view of 73 natural and human locations around the world as they are now, and with a swipe, as they were before climate change, urbanization and nature’s raw power affected them.

The app launches today from publisher HarperCollins, in partnership with Aimer Media, and the publicity blurb claims that it, “is set to become the definitive reference guide for all those interested in science, nature, photography and landscape.” Looks good to me. Cheap at launch, slightly more expensive later. Released just in time for Sunday’s Earth Day, obviously.

With the app, you can compare the town of Las Vegas in 1973 with its modern explosive metropolis, view the consistent deforestation and urbanization of Bolivia, witness lakes being created by melting glaciers in Peru and view before and after images of erupted Mount St. Helens and the aftermath of Hurricane Katrina.
