Very Cool Collection of Bird's-Eye-View Photos

There's a very cool slideshow on the Discovery Channel site in recognition of Earth Day 2009. The collection of photos that make up the "On Earth Day, a Bird's-Eye View" slideshow are beautifully done and are accompanied by explanatory text that highlight the impact of climate change -- from dust storms to floods to volcanic eruptions and earthquakes. The imagery is amazing - and certainly good for classroom sharing.
