The incredible IMO, Life after People series, an old 2008 series from the History Channel, all about what happens if we all suddenly disappeared, like Thanos snapped and wiped out 100% of all humans. It shows structures decaying and collapsing, and much much more. If you can somehow get all 20 episodes I highly recommend it (I say that because the only way I've found them is by torrenting them, they aren't ANYWHERE else, at least not every episode, Amazon Prime has like...4 episodes out of 10 of Season 1, and none of season 2. History Channel website doesn't even have every episode, nore YouTube or Google Movies & TV, or Netflix, or Hulu, or well, you get the idea.
