Satellite Photos Show Changing Earth

I first heard about this the other day while performing audio surveillance on NPR (The Liberal Hype Machine). Then it appeared on slashdot. Somebody has put together an atlas of satellite images taken over the last 3 decades (wow satellites are old now!) that compares locations from around the world, then and now. The contrast is impressive; large swaths of dense green land is replaced with the checkerboard of development. The images at that link are high res and may take a long time to download.
