"Scientists want to know when the extinction of the human race should be?
Judging from the current level of development of civilization, how many years do humans have left?
Civilization has developed for a long time, and even reached the peak of civilization, but the future of mankind is worrying, and scientists believe that human beings will become extinct at any time.
There is still life on the earth, human beings exist, and the existence of life also provides basic support for the survival of human beings, and this ecosystem will remain balanced, so when human beings no longer exist, the existence of life will also come to an end, so that there is no meaning for the existence of existing life.
Where will the future destiny of mankind go?
Scientists have also given different time predictions, 250 million years later?
climate change.
The planet that humans live on has a long history, and drastic changes continue to occur on Earth every day.
Natural phenomena such as meteorite impacts, volcanic eruptions, crustal movements, floods, and droughts will continue to occur, and the galaxies in the universe will also change.
The earliest life on Earth arose in the oceans and took a long time to evolve into the final organisms.
The earth's climate is also constantly changing, and perhaps there will be more extreme climates in the future, which will also pose a certain threat to the survival of human beings, and even cause a huge crisis to the survival preparation of human beings.
The Earth's climate is constantly changing in a long cycle, and if these changes are recorded in the calendar, they form a regular change that is caused by changes in the Earth's surface.
Nearly 20% of the Earth's land is land, but 80% is the ocean, so the oceans have the most direct impact on the planet.
The presence of oceans keeps the Earth's surface temperature in relatively high ranges.
When the oceans become warmer, they release a lot of energy, which also affects climate change.
The impact of the ocean on the ecological environment is mainly reflected in two aspects.
On the one hand, when the temperature of the sea continues to rise, it will cause the volume of the sea water to expand and produce thermal expansion and cold contraction, which will cause the continent to drift and cause the earth's crust to move.
On the other hand, when the temperature of the sea rises, more water vapor will enter the air, and the water vapor will absorb a lot of heat, which will further increase the temperature of the earth's surface, which is the greenhouse effect.
When the temperature of the ocean drops, it causes a change in the opposite direction, which also causes the temperature of the earth's surface to drop.
Similarly, it can be seen from the land that the impact of land on climate change is relatively small, and the temperature changes on land are mainly reflected in the temperature difference between day and night in spring and summer, and the changes between the four seasons.
Therefore, climate change on land has a relatively small impact on the temperature of the Earth's surface as a whole.
However, changes in the oceans are a very important factor in the impact of the Earth's surface temperature.
Scientists have found that a change in the ratio between land and sea can lead to the beginning of an ice age.
This is mainly because when the land area increases and the ocean area decreases, it will lead to a slowdown in the release of heat from the ocean, which will reduce the temperature of the earth's surface, and eventually lead to the emergence of ice ages.
This change has had a profound impact on human development.
It is precisely because of the role of the ocean that it affects the climate of the earth, and it also affects the life of human beings, and it plays a very important role in the survival of the earth.
So when predicting global climate change, changes in the ocean are a very important factor.
The movement of seafloor plates gradually changes the ratio of ocean area to land area, and this change is very slow, and it may take millions or even tens of millions of years to see noticeable changes.
However, such changes can also have a profound impact on the Earth's climate.
Scientists also predict that in the future there will be a supercontinent on Earth, or that it will be made up of multiple supercontinents.
This process is known as "continental drift".
This phenomenon is caused by the heat energy and gravity in the Earth's interior.
For these reasons, the Earth's rock plates move slowly, creating the effect of collision and separation.
This has led to the drift of the continents and the movement of the earth's crust.
Eventually, over a period of hundreds of millions of years, these continents will regroup into one supercontinent or supercontinents.
This phenomenon is called the "supercontinental cycle" and at the current rate, it occurs about once every 250 million years.
Many scientists believe that the evolutionary history of life on Earth is closely related to the formation of supercontinents.
Over the past few hundred million years, there have been many supercontinents forming and splitting on Earth.
Each reconstitution of the continents has brought new opportunities for the evolution of life on Earth, but also great challenges.
The formation of supercontinents leads to changes in the Earth's climate.
An increase in the size of the continent leads to a decrease in the area of the ocean, which in turn affects the flow and heat distribution of the ocean.
This will cause the global climate to become more extreme.
For example, inland areas may become drier and colder, while coastal areas are at greater risk of flooding and storms.
The formation of supercontinents also leads to the movement of the earth's crust and the eruption of volcanoes.
These natural phenomena have a direct impact on the Earth's ecosystems.
For example, volcanic eruptions can release large amounts of ash and gases, which could lead to a global climate decline or even a mass extinction.
There have been several mass extinction events in the evolutionary history of life, and five of them were caused by drastic changes in the earth's environment.
Today, scientists believe that the formation of supercontinents is an important cause of human extinction.
The formation of supercontinents leads to the extremeization of the environment on Earth, thus posing a threat to the survival of humanity.
Therefore, this prediction has aroused people's vigilance and concern about the future of humanity.
Extinction of the human race.
Scientists' predictions about the timing of human extinction are based on two main factors.
The first is humanity itself.
Humans themselves are a very dangerous species, as human guidance could lead to the collapse of entire ecosystems.
In the process of human development, many behaviors that cause damage to the ecological environment have been accumulated.
For example, over-hunting of animals, deforestation, mining of minerals, etc., can cause serious damage to ecosystems.
If these behaviors continue, they will eventually lead to the collapse of the entire ecosystem.
The second is the earth itself.
The earth itself is a huge ecosystem, and the balance of the ecosystem is constantly adjusted under the influence of the natural environment.
However, this adjustment is very slow, sometimes taking millions of years.
But if human activity interferes too much with this balance, it can lead to the collapse of ecosystems.
Scientists warn that if humanity does not change its current behavior towards the environment, the future of humanity will be in great jeopardy.
Humanity itself will become extinct due to internal strife and conflict, and may also become extinct due to environmental upheaval.
As a result, scientists believe that the time of human extinction was about 250 million years later.
The effects of environmental upheaval.
Is humanity's eventual extinction a "self-inflicted consequence"?
Human beings themselves have many vicious behaviors that produce the characteristics of showing off.
There are many discordant voices in society, and these discordant voices exist not only between humans themselves, but also other creatures in nature.
Humanity is also facing many existential crises in this process.
At the same time, human beings are constantly exploring other resources externally, and at the same time, they are also having an impact on their own planet.
The effects can be irreversible.
Scientists are constantly working to achieve human migration.
They believe that if humanity can successfully migrate to another planet, then it can avoid the fate of extinction on Earth.
At the moment, Mars is considered the most promising target.
Mars and Earth have many similarities, for example, Mars has seasonal changes, rotation and revolution cycles, etc.
At the same time, Mars also has the presence of water.
Scientists are working to find water sources on Mars in order to support human survival on Mars.
However, Mars also presents many challenges.
For example, there is a big difference between the environment of Mars and that of Earth.
The climate on Mars is cold, extremely dry, the atmosphere is thin, and the radiation is strong.
All of these factors will pose a threat to the survival of humanity.
Therefore, the survival of mankind on Mars will face great challenges.
At the same time, the gravity of Mars is only about 38% of that of Earth, which will have a certain impact on human physiology.
Therefore, the survival of humanity on Mars will be a long and arduous process.
Scientists predict that humanity will go extinct 250 million years later.
However, this timing is not absolute.
Many factors can affect this time, including changes in the natural environment, technological developments, etc.
Therefore, the main goal of humanity at present is to protect the planet so that it can survive on it in the future.
Epilogue:
In fact, not only humans, but also other living things on the earth may become extinct due to extreme environments.
When humans are no longer there, the natural ecology will also recover, and some organisms will even recover more.
This prediction by scientists is a cautionary tale for survival today, especially in the context of intensifying global climate change, and we must be aware that drastic changes in the environment may pose a huge threat to the survival of biological species.
Climate change leads to the deterioration of the natural environment, which adversely affects the survival of living things.
Humans are one of the root causes of environmental upheaval, but we can also do our part to improve the situation and protect our planet.
Therefore, we should actively promote global cooperation to jointly address the challenge of climate change and take effective measures to reduce greenhouse gas emissions and protect the environment.
Only in this way can we preserve hope for future human beings, prolong our own existence, and avoid the fate of extinction.
Extended reading:
The earth has been around for 4.6 billion years, so it seems that human existence may only be for a short time, so what is the point of us protecting the earth?
Human life is short and limited, but for the natural existence of the earth, it is very long.
The presence of man may have some impact on the planet, but the impact on the planet is very small.
It is impossible for humans to destroy the Earth's environment to a state where the Earth cannot be repaired, or to make life on Earth extinct.
Even if humanity goes extinct, the planet will still recover and the ecosystem will remain balanced.
It is impossible for human influence to destroy the laws of the earth itself.
Therefore, it is necessary to protect the planet, but it also needs to be done within our means.
