"Accident."

Every time Chu Tiange heard this word, it meant a major turning point in human destiny.

And most of the time, it is the beginning of a tragic fate.

So, what are the variables in this turning point?

[From 2030 to 2035, due to the opening of the Industry 4.0 era and entering the heyday of prosperity, Jiuzhou's industrialization level has increased significantly. Correspondingly, the air pollution index has also skyrocketed, and environmental pollution has become increasingly serious. 】

[Atmospheric pollutants, such as smoke, dust particles, nitrogen oxides, VOCs volatile organic compounds, non-methane gases, sulfides, ammonia compounds, ozone, benzene series, carbon dioxide and other toxic and harmful gases have soared in proportion, and the oxygen content has plummeted.

Decreased from 21% to 18%.]

[Because people have been breathing polluted and dirty air for a long time, even if the basic version of genetic medicine is now universally available, illness is still unavoidable. People's lifespan is gradually shortened, their cardiopulmonary function is weakened, and most people's bodies have become sub-healthy again, suffering from cardiovascular and cerebrovascular diseases.

, cancer, skin diseases, blood diseases, respiratory infections, pneumonia and other diseases occur frequently.】

Chu Tiange was walking in the streets and alleys and felt a strong pungent smell in the air.

It's a bit like industrial alcohol mixed with acidic haze. The pungent smell of high-concentration aromatic hydrocarbons goes straight to your nose and forehead. You can't go out without wearing a mask.

Looking up, the sky is gray and there is no sunlight scattered on a sunny day.

Not to mention looking at the stars and moon at night, in broad daylight you can't even see the blue sky, white clouds and the sun.

On the street of a certain commercial street.

"Ahem!"

A middle-aged couple walked hurriedly with support.

"Husband, just hold on, we'll be at the hospital soon."

The man was breathing heavily and his breathing rate was accelerated.

"I, I can't, I, vomit..."

puff!

The white mask on the middle-aged face was instantly soaked with blood.

The middle-aged man's vision went dark, he had no roots under his feet, lost support, and fell heavily to the ground.

The woman sat on the ground crying and begging for help from passers-by, but the passers-by around her were all in a hurry and panic, and no one was willing to step forward to help.

The woman called the emergency number, and all the ambulance numbers showed that they were busy. She had a complete mental breakdown.

Middle-aged people already suffer from wheezing. Nowadays, the air quality is too poor and the oxygen concentration ratio has dropped. The external natural environment has become the murderer of middle-aged people.

Social development is unbalanced and environmental pollution is becoming increasingly severe.

Is the reason due to air pollution?

No.

To be precise, there is an imbalance between industrial development and ecological environment development. One is still standing still, while the other has reached its peak.

It took just five years to complete the reform of the Industry 4.0 system that took fifty years to build. The leap forward development will inevitably weaken the momentum of progress in other fields.

This has led to serious air pollution, squeezing the oxygen space in the air, reducing the content of negative oxygen ions, and reducing the oxygen ratio from 21% to 18%. The crisis has come again, the oxygen crisis.

The 18% oxygen ratio is simply not enough for the normal oxygen supply to the creatures in Kyushu, and because hundreds of millions of creatures have been adapting to the 21% oxygen ratio environment for a long time, a sudden change in the environment may lead to chaos in the entire ecosystem.

For example, the middle-aged uncle just now suffered from asthma in an almost terrifying low-oxygen environment. The strong breathing pressure directly caused an acute relapse. He could not even get effective relief in time, and he would suffocate and die.

As we all know, the oxygen content will decrease by 1.6% for every one kilometer of elevation of the surface of the earth. Based on this calculation, people in plain areas are probably on a plateau of two thousand meters per capita.

Therefore, some people with weak respiratory function need to wear oxygen masks or portable ventilators before venturing out.

The screen changes.

When Chu Tiange came to Qinghu, the largest freshwater lake in the interior of Zhongzhou, he also encountered a survival crisis due to the decrease in oxygen concentration in the water.

On the water surface of Qinghu Lake, fish belly turned upside down and died, and white flowers floated.

Turning around to the east coast, the situation was exactly the same.

As far as the eye can see, there are pieces of dead fish, and you can't see the edge at a glance.

[In 2036, people realized the seriousness of the ecological environment, and Kyushu states successively issued orders to devote themselves to environmental air quality control. 】

[Jiuzhou Environmental Protection United jointly launched the blue sky rescue and protection plan to vigorously develop environmental technology. 】

The Zhongzhou Air Environment Governance Conference was held.

A group of experts and scholars in the environmental field gathered together.

"Let's talk about the situation first."

The person in charge of the conference spoke.

An expert said: "Due to the imbalanced reduction in oxygen concentration and the increase in the proportion of greenhouse gases such as carbon dioxide and methane, it has been measured that the average temperature across Kyushu has increased by three degrees compared to five years ago."

"Due to the intensification of thermal effects and the continued rise in temperature, the polar icebergs have seriously melted at a rate visible to the naked eye, causing the sea level to rise by about 20 meters. Some low-lying areas, such as coastal areas, tidal flats, and alluvial plain buffer zones

The entire area has been flooded."

Then, another scholar reported his own investigation: "According to sixty years of water and oxygen resource testing in various places in Kyushu from 1975 to 2035, the oxygen content in surface water has dropped by 9%, while the oxygen content in inland lakes and rivers deep water areas

, it dropped by more than 25%."

Next, experts, scholars, and professors in related fields published the data they investigated one after another. Every time a set of data or a fact was released, people felt as if their hearts had been hit by a hammer.

Shocking data and shocking events continue to occur, making people feel frightened. If this continues, within thirty years, humans will lose oxygen and can only rely on synthetic oxygen to survive.

Synthetic oxygen is expensive and long-term supply is unrealistic. Ordinary people...most people can only sit back and wait for death.

"We have to find a way to solve it!"

"It is urgent to stop the progress of Industry 4.0 and vigorously develop environmental technology, monitoring, and governance."

The conference established the goals and directions for future scientific and technological development. Environmental experts, scholars, scientific research teams and enterprise groups from various states, as well as related institutions and units, worked together to strive towards blue seas and blue skies.

At the lower seat of the conference, a middle-aged woman was deep in thought. It is not difficult to solve the problem of environmental pollution. It is easy to say that all she needs to do is stop the industrial state and vigorously improve environmental sanitation. Even if it does not work for a while, if she persists in the long term,

It will definitely take effect.

Yes, environmental management, water pollution control, for example, if you want to clean up a polluted lake, it will take at least ten to fifteen years, with sedimentation and purification every two years.

Air pollution belongs to the major industries, such as monitoring industries. As we all know, the air environment quality evaluation standards include several parameters such as dust particles pm2.5 and pm10, sulfur dioxide, nitrogen oxides, ozone and one carbon and two carbon.

For example, automobile exhaust emissions contribute about 20-30% to air pollution. Fortunately, Tianwen's new energy technology reform has directly reduced the contribution rate to about 3%. Otherwise, air pollution will be more serious, but it is useless. The industrial part has increased from 50% to about 3%.

Increase the value to more than 85%. In the final analysis, stop or clean up the heavy polluting industries, and everything will be easy to say.

However, it is obvious that no one has discovered the pain points that really harm human beings.

Oxygen itself!

That's right, it's a reduction in oxygen content and concentration.

Even if air pollution is solved and the proportion of oxygen increases, the oxygen concentration is still thin. No, it should be said that when the proportion of oxygen in the overall air increases, the concentration will be diluted.

The 18% ratio will continue to increase, while the concentration will continue to decrease!

After the meeting, the middle-aged woman left Gyeonggi Province worriedly and returned to Annan City.

[Due to the implementation of the Blue Sky Rescue Protection Plan, with the encouragement and cooperation of departments at all levels across Kyushu, the field of environmental science and technology has developed rapidly, and various management instruments and means have emerged in an endless stream, but the effect is not ideal. Environmental problems have still not been effectively alleviated and can only be temporarily stabilized.

Control emergencies.】

[It wasn’t until the emergence of megaoxobacteria, and a couple of top academics who showed their amazing talents and painstaking research, that the negative oxygen ion generator came out in 2040, and the environmental problem was solved. 】

Chu Tiange turned around and came to a paleontological research laboratory of Tianwen Group in Annan City.

"Jingmo, I succeeded!"

Li Shuijun, who has reached middle age, was ecstatically holding up the micro-culture medium. The agar block inside was covered with a layer of white frost.

"The successful cultivation of megaoxobacteria has increased the reaction efficiency of allergenic enzymes by a hundred times. Only one megaxobacterium can increase the ecological negative oxygen ion content in every cubic centimeter of space by five times! By analogy, we want our laboratory to become

To live in a longevity village, you only need to cultivate a microbial colony."

In the era of weak oxygen, the oxygen content in the air was less than 200 units/cm3, and there were only a few world-famous longevity villages in places where the oxygen content could exceed 1,000 units/cm3.

Adults need 13 billion negative oxygen ions every day to maintain life, but the natural environment such as people's work, life, entertainment venues, etc. can only provide about 1-1 billion negative oxygen ions.

The lack of negative oxygen ions is the fundamental reason for the low oxygen concentration in the air.

One thing needs to be understood: the air is not lacking in oxygen, it is lacking in oxygen!

As the oxide content increases, oxygen naturally decreases. Oxygen ions are positive divalent and combine with hydrogen ions, ammonium ions, carbon oxygen ions and sulfur ions in the air. It is self-evident how important negative oxygen ions are.

This was what Lin Jingmo had been worried about after the conference that year.

But in fact, in the past five years, air pollution control has been generally effective. The oxygen proportion has increased back to 21%, but the oxygen concentration has been diluted and is still consistent with the total amount of 18%.

On the core, the oxygen environment has not changed and improved, but has a downward trend.

But fortunately, five years ago, her husband, Professor Li Shuijun, a distinguished figure in the field of biology, successfully discovered the DNA of a super-archaeological organism—Megalobacterium!

Five years of cultivation research finally resulted in the reappearance of megaoxobacteria.

Megaxobacteria, the creators of the megaoxygen era 300 million years ago!

When the ecological negative oxygen ion content in the air environment is above 10,000 ions/cm3, it can be called a giant oxygen environment.

In the era of giant oxygen environment, the air is extremely fresh, the plants are lush and vigorous, the individual animals and plants are all large and strong, and they show extremely strong self-healing ability.

A typical example is from the Mesozoic era 300 million years ago, from the Triassic, to the Jurassic, to the Cretaceous, and to the dinosaur era that ended 65 million years ago, which is the core representative of the Megaxic Age.

At that time, the animals were tall and powerful, and the plants were thick and dense, all due to the influence of the giant oxygen environment.

"Megaoxobacteria..."
