What would it be like if there were no people on Earth?

Nobody knows, because nobody.

According to research, the earth has existed for 4.6 billion years now, and the emergence of human beings is only 7 million years old, what does this mean? Human beings are not the natives of the earth, and even if human beings become extinct one day, it probably won't have much impact on the earth.

If there are no human beings on the earth, then it is very chaotic. There's a lot of weeds, a lot of animal damage, and garbage everywhere, which is a terrible consequence.

If there were no human beings on the earth, then I think the environment of the earth must be very good, the air is very fresh, and there will be a lot of animals roaming around, and there will be a harmonious scene everywhere.

The earth would be particularly desolate without human beings. And animals will replace humans and dominate everything.

If there are no human beings on the earth, first of all, the environment may become better and better, and plants will develop more and more luxuriantly, but it may become more and more lonely.

If there were no humans on the planet, many rare animals would come out. And then those extinct animals will reappear on this earth. The sky will turn blue and the river will be clear.

There is a movie called "The Aftermath of the Catastrophe", which is very auspicious in the film.

Humans have lived on Earth since millions of years ago. Then the earth has also undergone some changes due to the existence of human beings. Some people are very curious, if there were no human beings on our earth, what would it be like?

The earth has been born for hundreds of millions of years, and the years of our human existence, but only a few million years, are not worth mentioning when comparing the years of the earth. In fact, if the time of human development is only more than 200,000 years, there is still a modern society like the present. But it is precisely because of the emergence of human beings that the earth has also undergone a lot of changes, for example, since the industrial revolution, we have continuously demanded the earth's resources, which has indeed damaged the earth's environment.

Another thing is that our human growth rate has been increasing, and today's population has exceeded 7 billion, which is very large, in fact, for the earth, this is a burden. In order to develop, human beings are constantly consuming the resources of the earth, and of course, there are some problems, such as global warming, environmental pollution, etc., all of which are caused by our human beings. If we continue to develop as we do now, what will the future become?

What would the earth be like without humans?

Scientists have also studied this issue in depth, believing that if there were no humans on Earth, there would be great changes in 1 billion years. First of all, under the continuous development of science and technology, the high technology created by human beings is no longer under the control of human beings. There is also the fact that the fuel will stop working after it runs out, and the nuclear reactions around the world will face strikes, which will lead to **, ** and then bring unimaginable disasters, first of all, the atmosphere and rivers will be polluted and severe radiation.

We humans live on the earth, we have our own housing, and we have built a lot of buildings, so in the future, it may collapse, and even if there are some buildings made of steel, it will be difficult to preserve them in the end. Buildings made of stone, such as the Great Wall of China, will last relatively longer, but buildings like those made of steel will face collapse.

Because our human survival also occupies a large part of the land area, then after the absence of humans, some wild plants will recover. Another animal will also be reborn, with free space, free predation, and the survival of the strong. Therefore, it is very likely that in 1 billion years, there will be no trace of human existence on the earth, and it will become a vibrant planet of animals and plants.

Do you agree with this speculation?

Question 1: What would people be like without the earth 1 Desertification of land will seriously break the ecosystem. 2 The air temperature will get hotter, the air will be less, and the oxidation of the plants.

3 In the summer, there are a lot of shady places, and it will be troublesome and painful for people to travel. In winter, the wind and sand will be very large. 4 The UV index will increase.

can induce disease. 5 The earth will become like an old man, without green life. 6 The wind is not good and the rain is not smooth, one word:

Rest! Question 2: What would happen to the planet without the ozone layer Without the ozone layer, the harm to the planet would be as follows:

a) Effects on human health.

1 increase in **cancer: ozone decreases by 1, and cancer patients increase by 4 6, mainly melanoid cancer.

2. Damage to the eyes and increase cataract patients.

3. Weaken immunity and increase the number of patients with infectious diseases.

2) Ecological impacts.

1. Reduction in the production of agricultural products and their quality. 2. Reducing fishery production. 3. Destruction of forests.

Question 3: What would happen to the Earth if the moon disappeared 1It is evident that it will not be dark at night, because there are still stars;

2.Without the traction of the Moon, the Earth's axis of rotation will change, so the seasons will change in different places;

3.There will no longer be tides in the sea;

Without tidal forces, the earth's crust is unstable due to the rapid rotation of the earth, and volcanoes are frequent. The length of day and night is too short to give birth to adapted species. The yellow-red angle will be virtually non-existent (the perturbation of other planets will have less effect), and there will be no alternation of seasons.

4.Meteors will increase;

Question 4: What would happen to the earth without oil? If there is no oil now, the cars that are widely used today will not be able to drive, and people in Jiangyin will not be able to adapt to the current situation, but there will be social unrest.

People will have to find ways to find something that can replace oil, and the earth's resources will become less and less.

According to the New Scientist, humans are the most dominant creatures on Earth in history. In just a few thousand years, our cities, farmlands, and pastures have encroached on more than one-third of the Earth's landmass. It is estimated that humans now occupy 40% of the planet's productivity.

The results of the direct approval are: the conversion of grasslands to arable land, the razing of forests, the drying up of underground aquifers, industrial waste, chemical pollution, invasive species, mass extinction of organisms, and the current climate variability. If other creatures on Earth were able, they would not hesitate to expel humanity.

Now, let's assume that this wish will come true: what will happen to the Earth if all the human beings on Earth – 6.5 billion of them (a number that is swelling) disappear from Earth tomorrow and are sent to distant stars to be transformed? The earth will be a better place if there are really no human beings on the earth, the earth will design its own future space, Mother Nature will once again dominate the earth, fields and pastures will become grasslands and forests again, air and water will be purified again, roads and cities will be wiped out.

John O'Locke, a biologist and animal and plant conservationist at the National Center for Ecological Analysis and Synthesis at the University of California, Barbara, said: "The sad truth is that once humanity does get out of this picture, the planet will be a better place. "But will the traces left by humans on Earth disappear completely?

Or, 1 million years from now, if someone visits Earth, will he see that an industrial society once ruled the planet? If there were no humans on Earth tomorrow, even if we were to see the changes in the Earth's orbit almost immediately, and the artificial lights that lit up the night sky would begin to go out, there would be no easier way for us to understand how humans had taken complete control of the Earth's surface.

There is only one human being on earth, and if it happens to be a young man, how will he survive and what will happen?

First of all, will the person know that he is the last human? I'm afraid not necessarily. If human beings are gradually disappearing, then in the later period it is likely to return to a more primitive state, that is, the various settlements of human beings are far apart, and the advanced means of transportation are stagnant because they do not have enough productivity, and communication is becoming less and less.

In this case, people will not be able to contact their own kind outside of their own circle, nor will they know how many people are left on the entire planet.

Then, the last human on Earth may not know that he is the only member of this race until the end, and only thinks that he is the only one left in this small settlement. Human instinct drives the person to look outward, to find other people of the same kind who don't actually exist.

The final journey.

If the earth at that time was just the disappearance of human beings and not the overall environment becoming unbearable, then the first problem before this person would definitely be survival. After the loss of many modern tools, humanity needs to use things that do not have to be replenished at all times, such as various cold weapons. After all, if a firearm is used, then the person's ammunition **, firearm maintenance and repair will be a big problem.

In the process, his best choice is to follow the traces of human settlements, because there are very likely traces of human beings in these places, and there are still resources left to support his survival. But as a lonely human looking for his kind, he couldn't possibly stop somewhere.

Humans are able to use nature and transform nature, largely because they have a solid social group, and we are able to unite and cooperate, divide labor reasonably, and build one miracle after another like a tiny ant building its own huge nest. If we become "one", then many things will seem powerless, and we will be extremely vulnerable to the forces of nature.

The last human will find that there are so many threats in nature, natural disasters, wild beasts, heat and cold, ......Even a single rain could have caused him a fatal illness. Therefore, the man's steps are bound to become slower and slower, for harsh nature will make him weaker and weaker.

Evolve from organic low-level lifeforms.

What if there are no humans? Then accept it calmly, then we will go to the moon! Or on the planet. Which place which? Go to a place that is suitable for survival. Just go to the a**?
