When I heard this question, I really found it interesting...cuz I never thought of it before. So do you wanna know what would really happen if we all disappeared from the world? Then keep on reading!
After a few hours after we would all disappear, all lights around the world would shut down.
After 10 days, farm animals and pets would die out due to starvation and dehydration.
A few weeks later, all those adorable small dog breeds would no longer exist as packs of bigger dogs would hunt them down and take them out.
One month later, cooling water at nuclear power plants would evaporate, leading to a series of explosions much stronger than Fukushima and Chernobyl disasters.
After 1 year, the sky would light up with the thousands of objects we have put in the Earth's orbit as they would come crashing back down.
After 25 years, after we would disappear, 75% of the planet's paved city streets and sidewalks will be covered in vegetation.
Cities like Las Vegas and Dubai would be smothered in sand as ''the desert would take what belongs to it''.
After 300 years, metal constructions like the Eiffel Tower and steel bridges, without maintenance, would fall appart and crumble to the ground.
Swamps, that once covered large parts of the world, would reappear.
The only evidence of man-made buildings after 10 000 years would be stone constructions, which can last several hundred thousand years.
