As the only intelligent life on the earth, human beings are good at summarizing experience and stimulating their creativity.

There have been five major extinction events in the history of the earth. Can human beings learn from it and learn how to deal with disasters?

Scientists have combined the entire earth's history for about 4.6 billion years and summarized the three tests that humans may face in the future.

Will the future human beings really have the ability to survive all this?

After the humans disappeared

Heaven and earth are unkind

Since the birth of the earth, the disasters above have never been cut off, and life has suffered several catastrophes. However, for some reason, life can always find its own way out.

Every time it is extinct, there are always some tenacious lives that survive tenaciously and create the next prosperous era and prosperity again.

Among them, five mass extinctions have been deeply engraved in the evolution of life and have left a mark to this day.

Destruction begins

The first mass extinction occurred in the late Ordovician period 440 million years ago, causing about 85% of species to become extinct.

The cause is that algae grow wildly, draining carbon dioxide in the atmosphere and oxygen in the water, causing global cooling, falling sea levels and lack of oxygen.

This incident gave birth to the birth of an organ - the lungs.

Because Ordovician creatures have not yet landed on land, many creatures rely on gill breathing, and they have become the biggest victims of this disaster.

Among them is a small group of animals who have learned to breathe oxygen directly in the air, which is the early prototype of the lungs.

Existing lung-bound fish

The second mass extinction occurred in the late Devonian period, about 365 million years ago, and the cause was exactly the same as the first one.

However, this time, the number of species extinct this time is not as high as the first time, only about 72%.

Because the spine animals landed, their feet appeared on vertebrates for the first time.

Although they can only climb in the mud at this time, this shows that vertebrates have the ability to leave water. Even if the sea level drops and the water body lacks oxygen, they have new places to go.

Vertebrate landing

However, evolution did not give creatures the ability to be invincible, and soon the most serious mass extinction in biological history came.

This extinction directly caused about 95% of species to disappear, and 97% of marine animals were directly erased.

This extinction was the mass extinction at the end of the Permian 250 million years ago, and the cause was the movement between the Earth's sections.

All geological disasters that can occur were staged during the mass extinction at the end of the Permian period. This is the time when the earth is most like hell.

Mass extinction at the end of the Permian period

The end-Triassic mass extinction was the most reference object for global warming. This was the fourth biological mass extinction in history, which occurred about 200 million years ago.

After about 50 million years of drought and heat, the earth ushered in a rainy season that lasted for 2 million years, and was irrigated from the desert to the forest.

However, the rainy season brings not rebirth, but destruction.

The changes in ground vegetation have caused a large group of plant-feeding animals to starve to death in the prosperity.

This extinction extinct 76% of species, and then the earth entered the prosperous Jurassic and officially opened the dinosaur era.

Triassic dinosaurs

The last mass extinction of organisms was the famous end-Cretaceous extinction, with about 75% to 80% of the creatures extinct, among which the lizard-shaped creatures represented by dinosaurs suffered severe damage.

This extinction is the doomsday of dinosaurs, but it is also the rebirth of mammals. The mass extinction resets the ecosystem.

The mammals that were originally being beaten by dinosaurs suddenly lost their natural enemies and became the new master of the earth.

It was this animal group that eventually gave birth to the only intelligent life form - humans.

So, what kind of crisis and extinction will mankind face in the future?

Global Warming

This is the most likely future disaster that humans think of because we are experiencing.

According to scientists' statistics, from the 19th century to today, the average temperature on the earth has risen by 0.9 to 1.1℃, a speed that surpasses the past of the earth.

According to this warming trend, we are likely to encounter a drought and hot era like the Triassic in the future.

Glaciers at the poles melted, sea levels rose by 66 meters, and the entire land was flooded with 10% to 20% of the land.

The forests disappeared on a large scale, replaced by grasslands and deserts, and the plants also turned into low shrubs.

Global Warming

The Sahara Desert will cross the Mediterranean Sea and engulf the entire southern Europe and West Asia.

The only suitable humans to live in by then are likely to be within the Arctic Circle and the Antarctic Circle.

The long-frozen Antarctic continent will be resurrected, from white to green.

A large number of organisms such as polar bears and penguins have become extinct, and the number of humans will also decrease, as the land area shrinks and the climate becomes no longer suitable for growing food, triggering a food crisis.

The ocean also acidifies due to the increase in carbon dioxide concentration, coral reefs disappear, and the ocean is dead, making it difficult for humans to catch edible fish.

Coral reefs die in large numbers

The earth is no longer suitable for inhabitation at this time, and humans can only leave the earth and find another way out.

But did humans at that time have that ability?

Perhaps humans can wait for the day when the temperature drops.

Because according to the laws of the earth, warming will make you cooler, and the earth will digest excess carbon dioxide by itself, but this cycle must be calculated in millions of years.

The earth itself is changing with hot and cold

Celestial impact

If global warming is the result of human beings themselves, it is impossible to prevent the evil flowers of sin, then the impact of foreigners is that it is impossible to prevent, and disasters are caused by the sky.

The dinosaur dynasty of that time was ended by an asteroid without saying anything, leaving only those fossils that proved the glory of the dinosaurs.

There are countless times in the history of the earth that have been hit by celestial bodies, and even the moon, the only natural satellite on Earth, was also caused by the collision between the earth and a celestial body.

But the impact happened about 4.5 billion years ago. There was no life on the earth at that time, so no fossils were left behind.

The Moon is Born

The asteroid about 66 million years ago left a deep mark on the creatures on Earth. It can be said that without it, humans could not have been born.

If the earth is hit by an asteroid in the future, who will become extinct in this catastrophe?

Who will usher in a new life in this disaster?

In 1994, Jupiter collided with a comet, and the impact lasted for dozens of hours, leaving a maximum diameter of tens of thousands of kilometers.

If the impact of the earth was the one that hit, then the earth is likely to be gone!

Comet collision

The most terrifying thing about celestial bodies is not the moment of the impact, but the series of chain reactions triggered afterwards, such as earthquakes, volcanic eruptions, and tsunamis. These disasters may last for tens of thousands of years.

Just like the dinosaurs back then, they did not all become extinct at the moment of impact, but became extinct step by step in the next tens of thousands of years.

This is a torment and a torture for species, especially how will it feel to think of humans, such as humans, watch themselves extinction?

In the future, in addition to the environment and the universe, human beings also have their own creation - artificial intelligence AI.

Humans may watch themselves extinction

The disaster of artificial intelligence

Although we nickname the artificial intelligence products on the market now "artificial intelligence retardant", these products show very poor thinking ability compared to the human brain.

Many people would not care about Hawking's warning about "beware of artificial intelligence".

Many people believe that artificial intelligence is created by humans, and humans are the "creator" of artificial intelligence, and they absolutely cannot surpass the "creator".

However, artificial intelligence defeated several smartest Go masters in humans, making people gasp.

Defeat human chess player

The manufacturing engineer is not a master of Go, but it can surpass human chess players.

This shows a terrible thing. The wisdom that humans are proud of is being surpassed by artificial intelligence.

Many people are worried about artificial intelligence. What they are afraid of is that artificial intelligence will destroy human beings slowly and "silently moisten things."

If people rely too much on artificial intelligence, they may regress in some ways, and artificial intelligence will gradually replace humans.

Artificial intelligence helps humans

Scientists believe that if artificial intelligence is fully used, most people's work will inevitably be replaced by artificial intelligence.

But the core work of human beings is that artificial intelligence cannot be inserted into it.

Because artificial intelligence cannot be separated from energy, for it, energy is food, just like humans eat.

If artificial intelligence really tries to suppress humans like what is played in science fiction films, then humans can directly cut off its energy and see when it will be finished.

Artificial intelligence and humans

These possible disasters in the future deserve attention. They are not nonsense that are hot-headed, but what is happening.
