The Aral Sea, 1973
Google spent eight years collecting historical imagery — aerial and satellite photographs from government fly-overs and other sources — and has integrated it into the newest version of Google Earth. By using a slider function, users can now travel back through time to see what places looked like decades ago. Above, the Aral Sea as it looked in 1973, before the onset of desertification.
