Have you ever wondered how long humans will last on Earth or how and when humans will go extinct? The question whether human extinction is inevitable or not has been discussed on many occasions, but the possible consequences of human extinction have received much less attention. Therefore, to give you a better idea of what might actually happen on Earth if the human extinction prediction came true, we compiled this post with 25 Unbelievable Ways Earth Would Change If Humans Became Extinct.
Without maintenance and fuel, most power plants (such as nuclear plants and wind turbines) would stop producing power. Consequently, most of the world would go dark.
Within days after human extinction, many pets and farm animals would die out due to starvation and dehydration.
All parasites that thrive on human existence, such as head lice and body lice, would go extinct.
Without power, electrical fences that used to keep livestock under control would stop working, releasing 1.5 billion cows, 1 billion pigs, and 20 billion chickens into the wild.
Pumps would stop working in subterranean tunnels and subway systems, which would result in massive floods.
