The Sky is Falling! The Sky is Falling!!

This is a still from the History Channel's gleefully Debbie-Downer series "Life After People". If you'd ever wondered what would happen if one day everyone on earth just vanished, this series is for you. Starting from 5 minutes after we're gone to 50,000 or so, it follows the collapse of our buildings, demolition of our cities and eventual erasure by the forces of nature and time.

I find it strangely entertaining to have it explained exactly the mechanism of our cities demise. As a matter of fact, this show and "Modern Marvels" have made the History Channel my default viewing station of choice..
