DH and I finally finished watching the History Channel documentary Life After People. It was interesting. The image of the Sears Tower crumbling freaked me out a bit but I was truly amazed at our planet's ability to heal itself if given the time and space to do so. They predicted that the Hoover Dam would be the last remaining human made structure standing. They took a look at the Chernobyl disaster 20 years after the fact and actually toured some of the safer areas.
The other item that struck a cord was that they predicted that cats may eventually evolve to have similar body types to flying squirrels just because they feel that cats will be living in the abandoned high rises while dogs will be mating with wolves and returning to their wild roots.
Dh was annoyed because they did start repeating themselves more in the second hour of what they had already gone over but I think it was just to make the point of where they were and where the show was headed. All in all, if you have the inclination and the time, it was an interesting look at what might be.
