Very cool this
First click on the link,and see places around the world like Las Vegas,The Amazon or Dubai and see how they have changed since 1984
but even better,is click on 'Explore the World' and
type in where you want to see,and see how it has changed.
http://world.time.com/timelapse/Las Vegas is a good one to view,seeing the city sprawling out into the desert...it's quite scary actually,and understandable when we're described as a disease on the planet

...but that goes just the same for practically everywhere
Dubai is also a good one to view with the landscape changing so much(manmade landscapes)
It's all done by NASA(off course) and Google
There is also a hell of a lot to read as well with the accompanying article
