What would the Earth look like in 100,000 years if humans were to become extinct

Twenty years after the disappearance of humans, the streets and crops will disappear, the country roads will be covered with wild plants, and the fields will be overgrown with weeds.

Human architecture will also decay rapidly. The first is those wooden houses, all of which will disappear in 100 years. Urban skyscrapers, made of glass and steel, will collapse within 200 years.

Brick, stone and concrete houses will last longer, but will also collapse after 1,000 years. If not, the bridge might last 200 years, but even the world's largest arch bridge will eventually collapse after 1,000 years. Within 250 years, human-built dams will also collapse.

The heavy metal pollution left behind by humans will also be gradually diluted after hundreds of years. Even a bustling metropolis like New York won't be long before nature breaks down, with tenacious tree roots toppling untrampled pavements and torn underground pipes, New York** parks filled with wolves, and commercial pubs filled with frogs in beer pools. Once the pumps pumping water for the subway stop working, the groundwater washes away the dirt under the highway and sidewalk, turning the highway and sidewalk into ravines, as in Manhattan in 1609, New York has at least 30 to 40 rivers.

Steven Kleimans, associate director of the Brooklyn Botanical Garden, said that within 200 years, tons of fallen leaves would fall in the drains of all New York parks, and if the lightning rod rusted and struck by lightning, the knee-length weeds that hadn't been cut for decades in the park or anywhere else would ignite in an instant, and the entire New York site would be set on fire. After a thousand years, the earth will return to the wild world, and thousands of years later, the earth will return to the prehistoric wild world. Without air pollution, the walls of cities would be covered with moss, creepers, poison ivy, and carrots, cauliflower, cabbage, Brussels sprouts, cauliflower, and other delicacies that were once indispensable on the human table would be reduced to wild vegetables.

After 200,000 years, the "human product" disappeared.

After the disappearance of human beings from the earth, almost all the remnants of civilization left by humans will disappear in 20,000 years, and in 50,000 years, all human remains on the earth will become difficult to trace archaeological clues, because glass and plastic will all dissolve. Only radioactive materials and a handful of man-made chemical contaminants will last longer – they are an invisible heritage of humanity. However, man-made chemical pollutants will also collapse within 200,000 years, leaving no "human product" to be found on Earth.

Although radioactive materials such as nuclear waste can last up to 2 million years, no one will associate them with humans in the vast expanse of the earth. In fact, if humans disappeared from the face of the earth for 200,000 years, it would be difficult to find evidence that humans ever lived.

What would happen to the planet if humans went extinct.

100,000 years of technology, unlike the ancient primitive 100,000 years, the blood of the earth has been drained and pain will be felt. By that time, will humans still be able to live on Earth? There are two scenarios, one is that human beings leave the solar system to establish their own homes on other planets similar to the earth, and migrate in batches and on a large scale, leaving the earth as the home planet of mankind and leaving it in the archives of cosmic history.

It is also possible that humanity has depleted the Earth's resources and never left the solar system, leaving it to fend for itself.

It is true that some people are now worried that human beings will control the power of technological warfare and destroy themselves, or develop artificial intelligence, which in turn will allow it to destroy human civilization, but human beings are extremely cautious species, and they are also fighting a war for world domination, not to destroy life, and real artificial intelligence will definitely set constraints on artificial intelligence in front of human beings.

According to the current speed of human scientific and technological development, at the end of the 19th century, cities can enter space on a large scale to establish space, and the corresponding moon base and Mars base will also be initially built, after 500 years, human beings are very likely to transfer to space or Mars to live, and over time there will be fewer and fewer human beings on the earth, and it is not easy to say that human beings will be in the solar system after 10,000 years, and maybe human children will not be able to distinguish the earth in the starry sky. God forbid. Only man can destroy man.

Due to the selfishness and greed of human beings for nature, they not only wantonly destroyed the ecological environment, but also launched fierce wars, invented endless **, and even possessed a nuclear ** that destroyed the world **. As long as a major power launches a nuclear missile, all mankind will be destroyed in the next nuclear war. Why is there a long 10,000 years?

Personally, I think that in 100,000 years, human beings will still exist on the earth, because with the development of science and technology, the quality of people has improved, and everyone is trying to protect the earth, so I think that human beings will still exist on the earth after 100,000 years.

I think that in 100,000 years, human beings will still exist on the earth, because the vitality of the earth is very tenacious and the carrying capacity is also very large, so I think that in 100,000 years, human beings will still exist on the earth.

It is possible that human beings will still exist on the earth, because after 100,000 years it is not very long, and our earth will definitely not be destroyed, so it will still exist on the earth.

Human beings can or may still exist on the earth, and since 100,000 years from now is not very long, the earth will not be destroyed, so they are still alive on the earth.

Humanity will not necessarily become extinct in millions of years, and humans can only guess what has not happened. Guessing may be wrong, or it may be right, for most people, it is meaningless to pay attention to this issue, and it is more important to live a good life for yourself.

In Darwin's theory of biological evolution, it is speculated that the origin of human beings is Africa, and the ancestors of human beings are apes. But at the time it was only speculation, and there were no fossils or evidence to support it. This is evidenced by the successive unearthing of fossils over time.

For millions of years, you think too much. With the vicious development of technology and viruses in the world today, 10,000 years is too long, and it will definitely not survive for that long. The greatest possibility is that the extinction of human beings is only a matter of the last few hundred years.

Possibly. Dr. Jiang Zhigang, chief researcher at the Institute of Zoology of the Chinese Academy of Sciences and executive deputy director of the Chinese Scientific Committee on Endangered Species, also believes that from the perspective of nature conservation biology, the earth has entered the sixth mass extinction period since the beginning of the industrial revolution.

I. Information on the Sixth Mass Extinction:

A team of researchers led by Jeremy Thomas of the Centre for Ecology and Hydrology in the UK reported in the recent issue of the journal Science that over the past 40 years, there has been a 54 percent decline in native bird species, 28 fewer native wild plant species and a staggering 71 percent fewer native butterfly species. Insects, which have long been considered to be numerous and resilient, are also beginning to face extinction. Based on this, scientists have deduced that the Earth is facing a sixth mass extinction.

2. The five mass extinctions in history are:

The first mass extinction: It occurred at the end of the Ordovician period, 4.4 billion years ago, when about 85 species went extinct.

The second mass extinction: in the late Devonian period, about 36.5 billion years ago, marine life was devastated.

The third mass extinction: At the end of the Permian period, about 2.5 billion years ago, it was the largest and most severe in the history of the earth, with about 96 species extinct on the earth, including 90 percent of marine life and 70 percent of terrestrial vertebrates.

The fourth mass extinction: 18.5 billion years ago, 80 reptiles became extinct.

The development of medicine has led to the elimination of the immune function of the human gene pool in the opposite direction. There are fewer and fewer genotypes with excellent immune function, 16%, 8%, 4%, 2%, 1%, 0? Immunodeficiency of the cancer genome, cultivated under the medical technology of $1 million.

Constant replication and inheritance of the next generation of immune degeneration genomes could not fight the cholera smallpox diagnosis of the past. Over-based ponthose, vaccine. Once the virus evolves to defeat the vaccine, the genetically degraded immune function of humans cannot defeat the HIV virus?

After 300 years, the genetic degree of human immunity is highly genetically degenerated, which leads to the HIV virus, and the evolution of plague over antibiotics, resulting in the extinction of human beings by superbugs and superviruses, and the extinction of human beings. Two reasons for the demise of humanity! Medical developments have cultivated the Malthusian mathematical trap of immunogenetic degeneration of cancer genomes.

Newton's gravitational attraction of genetic degradation of immune function populations, attracting superbugs, superviruses HIV, leading to the extinction of humans?

Most of them probably will, because the sun people need to be the sun to the sun, but the sun has started to show that black thing. The black stuff will fill all parts of the sun in tens of thousands of years. As the saying goes, without the sun there would be no lovely world for us, so the sun is very important, and if the sun is really really broken or something.

Then we humans are really likely to become extinct.

I think that there is no living thing that is eternal, that there is life on the earth, that there is water, plants, soil, animals, etc., and that the universe is indeed very mysterious. The magic of genes and so on.

No matter how it is exterminated, let's exterminate cockroaches and mosquitoes first.

It is not yet known for sure, leading to the extinction of humanity, or whether an asteroid hitting the Earth. It is possible that humanity has migrated to other planets. Either a nuclear war broke out, or new resources and energy sources were discovered.

Stephen Hawking predicted that humanity would become extinct within 300 years because of artificial intelligence (which would be smarter than humans) or extraterrestrial civilizations (that is, aliens, Hawking has always warned humans not to send signals to outer space) or a celestial body crashing into Earth.

Probably not, unless something cataclysmic happens. Even if it happens, it will not be extinct, so exaggerated, you must know how advanced technology is, how tenacious the vitality of people is, there will definitely be survivors. Life will go on forever....

We humans are not going extinct.

No then.

Biology is actually a highly complex chemical and physical composition, that is, biology comes into being from nothing. From a biological point of view, humanity is extinct. But from a physical and chemical point of view, the impact of human beings on the universe is still there.

The information and items that remain can give rise to new civilizations.

Believe me, extinct from AIDS!

With an average of one mass extinction every 70 million years, it seems that it is almost the same as the last mass extinction.

If you don't take care of the environment, you will become extinct.

If we take care of the environment, we will not go extinct.

Humanity will one day be wiped out by nature, and the world will be devastated.

Definitely, this is the law of biological evolution, where there is extinction, there will be new species that are more adapted to the environment.

Human footprints, things used by human beings, buildings, these traces will still remain on the earth.

Some of our products and technologies, as well as traces of our survival, will be useful evidence for future generations to study us long after.

Because of their extremely long lifespan, these nuclear wastes are likely to continue to react for billions of years after humans disappear.

No, once a creature is extinct, it will no longer be on Earth.

In the hundreds of millions of years of life on Earth, there has not been a single organism that has evolved again after extinction.

The appearance of human beings on Earth is itself an accident. Scientists have taken the initial single-celled organism as a starting point, through a variety of models, and many computer simulations, but have not "seen" the appearance of humans in the models, indicating that the appearance of humans on the earth is likely to be really just an accidental phenomenon. Therefore, scientists believe that if life on Earth evolves from scratch, intelligent life may evolve again, but the possibility of human beings reappearing is very small.

According to this, if humans disappear from the earth, no matter how long it takes, other intelligent beings may evolve, but not humans.

The pace of evolution will not stop. But it is not known whether humans will come.

The birth of human beings is a certain accident, and even if the earth's environment returns to the beginning, there will be no human beings again without various coincidences. Why is it not easy for humans to reappear on Earth?

1) The history of mankind.

Human history is 6 million years old, and the current age of the earth is 4.6 billion years.

Theoretically, the process of human origin is divided into three stages: the Australopithecus stage; also man and ape stage; The stage of a person who can make tools. The latter stage includes ape-man.

In 1859, the British biologist Charles Darwin published the book "The Origin of Species", which clarified the development of organisms from low to high, from simple to complex. In 1871, he published The Origin of Man and the Choice of Sexuality, in which he cited many evidences that humans evolved from the extinct Australopithecus.

In other words, it took 6 million years of evolution for humans to become modern humans.

However, this time is too short for the development of the earth. So why can't humans appear at other times on Earth? Obviously, the emergence of human beings requires a lot of fortuitous conditions to bring about it.

2) New species emerge after the extinction of humans.

It can be said that the appearance of life is random. When humans die out, it is likely that all other species have disappeared. Earth's restart button will also initiate the birth of new life.

However, the new species is probably not the current species, and the birth of human beings is based on the development of existing species, so the evolution of new species is likely not to develop human beings.

3) Human beings are just special individuals.

The emergence of human beings is not inevitable, there have been many extinctions of organisms on the earth for billions of years, and now it seems that many extinct creatures will not reappear, and human beings are only one of the biological species on the earth, so it is likely that they will not appear again after extinction.
