20 Things That Would Happen if Humans Disappeared From Earth Overnight

Nuclear plants will melt down

Although nuclear plants have stopped producing power, that doesn’t mean they would be harmless if not manned by humans.

About a month after a mass human exit, emergency generators would run out and the cooling pools used to control nuclear substances would evaporate, causing mass nuclear explosions far worse than Chernobyl or Fukushima. Pockets of dangerous radiation that could potentially remain for thousands of years would span the globe.

Satellites will fall from the sky

About a year into the world’s existence without humans, the night sky will begin to look very different as satellites begin to fall. Thousands of objects sent by man into orbit will slowly start to fall over the course of several years, appearing like shooting stars in the sky. Some of the furthest satellites could continue to orbit for decades before eventually falling back to earth.

Vegetation will revert back to its original form

Over the centuries, humans have managed to crossbreed and perfect fruits and vegetables to make them more plentiful, palatable and easier to grow. In just two short decades without human cultivation, vegetation will revert back to its original strains and some of your favorite healthy foods will be virtually unrecognizable in their wild forms.

Homes will crumble

After just a couple of winters without heat, pipes will begin to burst and homes will slowly start to deteriorate from the inside out. Most homes are built predominantly using timber and after about twenty or thirty years, the ones that haven’t already burned to the ground by mass fires caused by lightning strikes or other aforementioned disasters will begin to crumble and rot.
