20 Things That Would Happen if Humans Disappeared From Earth Overnight
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.
Some cities will grow over
Just 25 years after man’s disappearance, urban landscapes will be overgrown by vegetation.
Without cars to drive on them, roads will be covered in moss and grasses. The forests and swamps that were previously paved over will have reclaimed their territory and places like Central Park will expand and take over the city. Within a few hundred years, urban areas and forests will be almost undiscernible from one another.
