After humans disappear, how long will it take for the earth to completely erase the traces of human existence?

Humans are the most intelligent life on earth. The birth of human beings has added a lot of color to the earth. If human beings did not appear, then the mysteries of the earth and the universe may never be revealed. From the development of human civilization to the present, a total of experience For thousands of years, in these short thousands of years, human beings have stood at the top of the food chain and walked out of the earth, which shows that the speed of human technology development is still very fast. Modern science believes that human beings are made of apes. Scientists have found that human ancestors should have been born 3 million years ago after years of archaeological research.

At that time, there were many ferocious creatures on the earth. In order to survive, ape creatures could only choose to live in groups. Living in groups not only effectively resisted foreign invaders, but also increased the chances of communicating with each other and communicated frequently. It can speed up the development of the brain. In addition, human ancestors also learned to use fire. The emergence of fire represents the beginning of human ancestors' civilization. We know that many animals are very afraid of fire. Fire can not only effectively resist the attack of foreign creatures. Offensive, and can also roast food. Scientists have concluded through research that roasted food not only tastes delicious, but also has higher nutritional value than raw food. Because human ancestors ate roasted food for a long time, so Their brains will grow smarter and smarter, and eventually they will successfully evolve into humans.

Nowadays, relying on their own wisdom, human beings have built their own homes on the earth, and have also invented many advanced weapons and means of transportation, such as automobiles, ships, planes, rockets, high-rise buildings, bridges, etc. It is built with the wisdom of human beings, but human beings are not satisfied with this. At present, human beings are exploring the mysteries of the universe. Although there are many mysteries in the universe, human beings have not yet been able to solve them. However, with the advancement of human technology, one day, human beings will We will be able to solve all the mysteries in the universe, and then we will be able to stand at the top of the biological chain of the universe. I hope this day will come sooner.

However, as human beings accelerate the development of science and technology, it also causes pollution to the earth's environment. A large amount of industrial waste gas is discharged into the air, resulting in an increase in the content of carbon dioxide in the atmosphere. Now the global greenhouse effect is getting more and more serious, and the glaciers in the Antarctic and Arctic have begun to Melting, if it continues to develop, in another 1000 years, all the glaciers in the Antarctic and Arctic will melt, and the coastal cities will be submerged. The original land area only accounts for 29% of the earth's surface. , then the land area on the earth will become smaller. In addition, a large amount of industrial waste water is discharged into rivers, which not only pollutes water resources, but also pollutes marine organisms. After these marine organisms are eaten by humans, they will also give harm to human health. In the long run, human beings will eventually perish.

So if human beings disappear completely, how long will it take for the earth to erase the traces of human existence? For this question, I believe many friends are very curious. After all, we also want to know how long the civilization we created on earth can last? Scientists believe that when humans disappear for a day, all human vehicles will be paralyzed. There are all kinds of vehicles parked on the road, just like scrap iron. There is a problem with management, no power station means that the lights will no longer be on at night, and now we have bright lights at night, when the earth's night will only be the moon and the stars. The earth returns to primitive society in an instant.

When humans disappear for a month, the underground water pipes will burst, and a lot of water will flow out of the ground, and the water will flood the streets and alleys. At this time, weeds will start to grow. After a few weeks of growth, weeds will spread all over the streets and alleys. One year after the disappearance of human beings, the cities built by human beings will be covered with plants, and the plants will be covered with high-rise buildings. The cities that human beings have worked hard to build for thousands of years will be eroded by nature. At the same time, a large number of animals will begin to flood in. Cities, carnivores that originally lived in the wilderness, have also begun to invade cities. They will hunt in cities, which means that the earth has returned to the era of predators.

When humans disappear for 50 years, cities will be completely covered by plants, and houses built by humans will begin to collapse. At this time, nature will begin to slowly merge, and satellites and probes launched by humans will be paralyzed, and then float in space and become space Garbage, 1000 years after the disappearance of human beings, all high-rise buildings built by human beings will collapse, and there will be no buildings taller than trees on earth. By then, the earth will be full of ruins, plants and animals will be all over the world, when human beings disappear 10,000 Years later, due to the lush growth of plants on the earth, the earth's environment has become better and better, the carbon dioxide in the earth's atmosphere has begun to decrease, and the air has become cleaner and cleaner.

When human beings disappear for 100 million years, human civilization will completely disappear from the earth, and we will not be able to find any traces of human civilization. Even plastic, a polymer compound, will be decomposed by nature. Humans once thought that A proud civilization, since it is so vulnerable in the face of nature, after the disappearance of human beings, the earth will continue to rotate and revolve, and the solar system still does not change. It is possible that intelligent life will re-evolve on the earth, and then new intelligent life. Continue to continue the new civilization. Human beings are not unique to the earth. On the contrary, the earth is unique to human beings today. If there is no earth, then human beings cannot survive.

Although scientists have discovered planets similar to Earth in the universe, these planets are too far away from us. At the current speed of human flight, it will never be possible to fly past, so the only thing humans can do now is to protect our earth environment , once the earth's environment is destroyed, the earth will start its self-repair function. For the earth, human beings may be bacteria. After all human beings are removed, the earth's ecology will be completely restored. Therefore, while developing technology, human beings must also Protect our earth's environment, so that human civilization can develop for a long time. What do you want to say about this?
