What would happen if all humans suddenly vanished from the face of the planet? That freaky thought experiment is explored in a new video from YouTube's AsapSCIENCE (see above).
The video details things that might happen -- from shortly after our disappearance to thousands of years after the fact. Cities would be wiped out by fire or other natural disasters, and even the sturdiest buildings and other man-made structures would eventually crumble.
Our pets probably wouldn't fare so well either, having a hard time holding their own against wolves and other predators. On the positive side, other remaining species -- even those whose populations have been decimated by human activity -- might bounce back.
The atmosphere might bounce back too, although certain pollutants would stick around for a very long time.
It’s a sobering thought, indeed.
