If doomsday struck, and humans were wiped off the face of the Earth, what would happen to our planet?

According to a recent video, it won't take long for Earth to 'reset' itself - but the process would be terrifying.

Within a few hours most of the lights would turn off and within months, nuclear disasters would strike across the planet.

After thousands of years the only evidence of our existence would be in the form of stone structures like the Great Wall of China or Mount Rushmore.

'The reason is irrelevant, just imagine the results,' the narrator of the video, from viral YouTube channel '#Mind Warehouse', says.

The video was put together using footage created by National Geographic.

The video animations came from Life After People, a television series on which scientists, structural engineers, and other experts speculate about what might become of Earth should humanity instantly disappear.

A few hours after humans disappear, most of the lights around the world will shut off because most of the power stations will not be able to run.

Fossil fuels power plants would run out of fuel and solar panels would eventually get covered in dust.

The only power plants still running would be hydroelectric stations.

'On the west of the United States, the generators of Hoover Dam are activated by the water flow from Lake Meade,' the narrator says. 'Thus, it can be left unattended for several months, or even years.'
