What will happen to the earth after the destruction of mankind?

It is said that human beings began to end the "hunting" life similar to other animals about 1 10,000 years ago and turned into a "home" state. After "settling down", mankind gradually "established a career" and created what we now call "civilization", which has brought earth-shaking changes to the face of the whole planet.

But what will happen to these things if one day humans suddenly disappear?

After a few hours of human disappearance, the power supply will be gradually interrupted. The first one is the coal-fired power plant with the most frequent demand for fuel. Affected by this, when the first night after the disappearance of human beings comes, some areas where human beings once lived will return to the light of the moon and the stars in prehistoric times.

A few days after people disappear, subway tunnels in some coastal cities will be flooded because of the stop of drainage equipment.

A few weeks after the disappearance of human beings, most of the animals raised by human beings have starved to death. Those who escaped from the "cage" will forage everywhere and return to the natural competition in prehistoric times.

A few months after people disappear, wild animals will cross the "thunder pool" and invade cities, competing with animals in cities for the "world".

After a few years of human disappearance, roads will be broken one after another, and plants will grow tenaciously from the cracks and gradually cover the roads.

After decades of human disappearance, the roofs of residential houses will collapse one after another; Some large buildings, such as Shanghai Oriental Pearl TV Tower, are built in coastal areas, which are prone to floods and will collapse as a whole because of foundation rot; Spacecraft in low orbit will fall one after another.

Hundreds of years after the disappearance of human beings, almost all large buildings will cease to exist and gradually be covered by floating soil and vegetation.

After 654.38 million years, the only evidence of human existence is large stone buildings, such as the Egyptian pyramids, the Great Wall of China, and the stone carvings on the President's Hill in the United States.

150,000 years later, plastic bottles and some glass fragments will become the last evidence of the existence of human civilization.

After 30 million years, plastic bottles and glass fragments will no longer exist.

It can be seen that our earth is an extremely stable system, which will gradually remove the garbage we create.

If there are new intelligent creatures on the earth after 300 million years, they won't even realize that there was a human civilization on the earth.

You see, the earth can live well without humans. But without the earth, we are finished.

If there were no humans, the earth would be much easier, at least back to the Cretaceous. First, it can reduce the air pollution in the natural environment, and second, it can reduce the ecological balance. Now that human beings are extinct, they are their natural enemies. The above are personal opinions and are for reference only.

Ok, don't worry, let's think about this problem slowly. If one day, mankind suddenly disappears from this world, first of all,

Because I had my mobile phone before I disappeared, I must have dropped it as soon as I disappeared.

Planes and helicopters will fall from the sky (even those self-driving planes will eventually fall to the ground because of running out of fuel).

My pet will always be trapped in the house and starve to death.

Animals in circuses and zoos will have the same tragic ending as my pets.

In the long run, the global oxygen consumption will definitely decrease.

Our mother earth can finally be quiet for a while. All kinds of messy noises can finally disappear from this earth.

Without human beings, vehicles can't run, and environmental pollution such as air pollution will no longer exist.

If you are another species, congratulations. Next, you will witness the most serious and biggest traffic accident in the world so far. All vehicles on the road will collide, explode and burn when they suddenly lose control.

The status you posted on various social networking sites will never receive praise again, and your space will stay in the last conversation you may have inadvertently posted.

Astronauts on missions in outer space don't know what happened, but they can't receive any signals from the Earth's General Command any more.

The numbers on my electricity bill will keep rolling, and the lights in every room, the TV in the living room and the air purifier in the room will always be on. Haha, magically, no one will turn off the switch in the end.

There will be no more pruning plants in this world. Soon, every corner of the earth will be covered with green vegetation. Without the interference of human activities, the number of wild animals and plants will increase dramatically in a short time.

Imagine what the world would be like without human beings.

If human beings die, within a few hours, coal-fired power plants, wind turbines and solar panels will collapse because of unmanned operation, so the power supply will be cut off, and the brightly lit market will fall into darkness like a silent hill because there is no power supply.

As the pumps stop working, most subways and tunnels will be flooded in a few days.

10 days later, animals and domestic pets on the farm died in large numbers because they were not fed and cared for, and unsupervised large dogs would hunt other small animals in groups.

A month later, the cooling water of the nuclear power plant was exhausted, the fuel rods exploded due to excessive temperature, and the Chernobyl nuclear explosion was repeated all over the world. Nuclear pollution has become a global event.

A year later, the unmanned satellite crashed due to aging and celestial gravity. Most of it will fall to the ground through the atmosphere under the action of gravity. The picture shows the satellite map around the earth at this stage. Although there is an atmospheric buffer, once a large number of satellites fall, the consequences will be as serious as an asteroid hitting the earth.

Twenty-five years later, vegetation covered cities, and some cities in arid areas were buried under yellow sand.

300 years later, under the erosion of wind and rain, steel rotted and the tall tower bridge turned into ruins.

10000 years later, the only trace of human existence is stone carving. The statues of the Sphinx, the Great Wall of Wan Li and the Presidential Mountain stand silently, telling the glory of human civilization.

Whether humans disappear from the earth is irrelevant to the earth. It doesn't matter whether you are here or not. It doesn't matter to the earth what they become as usual. At that time, no one would destroy them. Maybe that's the paradise for moving things.

To put it bluntly, human beings are creatures on the earth, a link in the food chain and standing at the top. When all humans disappear, some creatures will have no natural enemies, and their reproduction will accelerate dramatically. At this time, the earth will enter a link of the law of the jungle, and life will evolve into a new cycle. At this time, the earth may regain its original vitality, and the air quality and environment may be many times better than now. Maybe after another evolution, there will be another intelligent creature or a smarter creature.

It has nothing to do with humans.

What will happen to the world if humans disappear? How long can the traces of human civilization last?

The first month after the "disappearance" of human beings should be disastrous for the human world. The world's energy supply system will be completely paralyzed, and the emergency fuel of nuclear power plants will be used up within one week, resulting in the water outside the nuclear reactor being unable to be cooled circularly. Soon, hundreds of nuclear reactors around the world will burn, melt or even explode due to overheating, which is equivalent to hundreds of Chernobyl-type or Hiroshima-type nuclear leakage disasters happening at the same time. Fires will happen from time to time, and most cities will be swallowed up by fires and become ruins.

More than 654.38+0.5 billion cows, nearly 654.38+0 billion pigs, and more than 20 billion chickens, cats and dogs will break through their fences, but if there is no human feeding, most livestock will starve to death. Or eaten by other carnivores. Cities, especially coastal cities, will become a water world, because the pumps for pumping water will no longer work. This disastrous scene won't last long. In a few years, the city will be slowly occupied by plants, and water and weeds will corrode the whole city from its roots.

Most buildings in the city will collapse within 20 years, and almost all civil buildings will be in ruins after 30 years under the attack of plants. A hundred years later, various FRP structures slowly corroded and then collapsed. For example, the Eiffel Tower in Paris will be severely corroded and destroyed, and all cars and bridges will suffer a similar fate.

500 years later, all the cities were covered with forests. Especially those cities with temperate climate can only see dense forests, and there are only a few relics left in the once brilliant high-rise buildings. At this time, the earth will once again become a paradise for animals and plants.

Books, photos and electronic data, as the carriers of human history and civilization, disappeared within a hundred years. Unless these things are buried in sand that lacks air and water, they may survive for thousands of years or even thousands of years. But perhaps, as Luo Ji said in "Three-body", words are carved in stone. Ten thousand years later, among all human inventions, perhaps only plastic products and some metal statues can prove that human beings once existed. Plastic products are probably the least suitable for nature. Even in the past 65438+ 10 million years, most plastic bags will not completely degrade and disappear. If aliens come to the earth at this time, they can only find bronze statues, gold and silver utensils and a lot of plastic garbage remains. However, these things are hidden underground or under the sea, so it is not easy to dig.

In 50,000 years, glass and plastic will be dissolved, and all human remains on the earth will be hard to find. After 200,000 years, there will be no traces of human habitation on the earth. /kloc-what will the earth look like in 0/0 million years? Will there be new intelligent life? That's not clear. After all, human history is only a few hundred thousand years, which is too short!

If you are interested, you can watch the sci-fi documentary "The World after Human Disappeared", and show you an amazing visual journey through the final hypothesis.

It depends on how humans became extinct. Generally speaking, there is no reason for human extinction. Because the earth is still young and light, it will not be destroyed by the collision of other planets. Only nuclear weapons can destroy the surface of the earth. In this way, since human beings are extinct, all living things are extinct. However, I don't believe that people are dead, have souls and become ghosts. It's just that there is no human loneliness. The extent to which nuclear weapons destroy human, animal and plant life is unknown. However, the water surface area should be greatly increased, except for the water area, which is bare. In a few years, all the land will still be green. Because the seeds of plant life are not destroyed at the bottom of the river, lake and shallow sea. The green earth may reappear, but the signs of animal life may never appear again.

The earth doesn't necessarily need humans, but humans need the earth. Without human beings, the earth will slowly repair the wounds caused by human beings and recover vigorously.
