This video explores the hypothetical scenario of what would happen to Earth if all human beings suddenly disappeared without a trace, detailing the timeline of ecological and infrastructural changes over millions of years.

From the video

Answers: What would happen to Earth if humans disappeared?

• Earth without humans
• infrastructure decay after human extinction
• ecological recovery and succession
• nuclear power plant meltdowns
• urban wildlife and pest populations

What it concludes

• All fossil fuel plants around the world would shut down within the first day of human absence, causing global electrical blackouts.
• Without manual labor, subway systems would completely flood within days due to unpumped water.
• Unmaintained nuclear power plants would eventually overheat and explode, releasing significant radioactive fallout.
• Domesticated cats and dogs would struggle to survive, with cats having a better chance of survival as solitary hunters.
• Man-made structures made of metal and glass would degrade and collapse first, while stone structures like the Great Wall of China and Pyramids of Giza would remain intact for thousands of years.
• After 100 million years, the only remaining evidence of human life on Earth would be fossilized bones, plastics, and Mount Rushmore.
