In the garage of the city police station, Qin Lan and other special police officers were sorting out equipment. They had a field mission today and went to the train station to receive a batch of equipment that had arrived in the city from the railway.
"Li Tou, what equipment are we going to receive today?" While Qin Lan was checking the gun in his hand, the teammates beside him curiously asked the leader: "Isn't it usually the city that receives supplies?" Are you from the government? Why do you want our SWAT team to pick up the equipment today?”
"Didn't you listen carefully when Team D and the political commissar gave a briefing just now? Didn't I say that it is a batch of important materials that are vital to the refuge's life and death, so this time it is an armed escort and requires our SWAT team to receive it." The leader, Li Tou, was also wearing field equipment. While checking the ammunition, he answered the questions of his subordinates.
Just hearing Li Tou's answer, Qin Lan had some questions. She asked Li Tou: "Li Tou, shouldn't things like escorting and protection be handled by the armed police? Why did our special police get involved?"
In Yanguo, the armed forces controlled by the state are divided into three parts: the army, the police and the armed police.
Among them, the army is responsible for external operations and safeguarding the country's territorial sovereignty. The police is responsible for maintaining social security internally and combating crime. The armed police is between the police and the army and does not belong to the police. However, it is organized according to the requirements and establishment of the army. It is mainly responsible for: Local security and emergency response.
In terms of functions, escorting important supplies should indeed be a matter for the armed police.
Li Tou himself was a little confused about this issue, but now that the mission had been assigned, it was impossible for them to say that they would carry out the mission after they figured it out.
So Li Tou could only say to Qin Lan: "Maybe the city government is doing something else. Things are different now. Some things may not be according to the rules."
Qin Lan didn't know what to say to Li Tou's words. She just wanted to ask why it was not the armed police escort but the special police escort this time. But what Li Tou said touched the minds of some people in the city government. This was inevitable. Qin Lan felt helpless.
Although the country is still there and government agencies are still functioning normally, the end of the world is the end of the world. Although many things still look the same as before, they are actually different.
Li Tou may also feel that what he said is a bit inappropriate, so he patted Qin Lan on the shoulder and said to her: "Don't think so much, maybe it's just that the armed police can't spare manpower? This kind of thing has happened before. Perform the mission first, and think about it later when you come back.”
Hearing what Li Tou said, Qin Lan also suppressed the messy thoughts in her mind and focused on the task.
————————————
The disaster caused by the meteorite impact destroyed the original human civilization. Although there are not many survivors now, these humans have only survived.
For these survivors, the most important thing is to survive. As for rebuilding human civilization, although the country is rebuilding after the disaster, the progress is very slow. It is still a very long process to truly rebuild human civilization.
What this apocalyptic disaster has brought is darkness and cold. Although everything seems to be okay now, it seems that it will not be long before people can leave the shelter and start rebuilding after the disaster.
But in fact, the real test brought about by the meteorite impact has not yet come.
Anyone who has studied biology in junior high school knows that the growth of all things depends on the sun. Without sunlight, most life on the earth cannot survive.
But now, the dust kicked up by the meteorite has obscured the sky and lost the sunlight. Not only has the temperature dropped, but the ecology that could have been gradually restored has been completely destroyed.
Previous global fires have burned more than 90% of the vegetation on the earth, and a large amount of carbon dioxide has been emitted into the air. This has maintained the temperature drop in a short period of time, but without sunlight, the temperature will still cool down quickly.
Many people may not have any idea about this, but you only need to think about the fact that the four seasons on the earth can cause temperature fluctuations of dozens of degrees just because of changes in the direct point of the sun, and you can understand what the loss of sunlight means to the earth.
And there is a more critical issue here, that is, without light, photosynthesis cannot proceed. Without photosynthesis, carbon dioxide in the air will not be converted into oxygen.
Oxygen is very critical to life. The larger the body, the more dependent the life is on oxygen. There are only some anaerobic bacteria that can survive without oxygen on the earth. Other organisms, whether plants or animals, cannot survive without oxygen. Oxygen is required to sustain life.
A fire not only burns the forest vegetation that can convert carbon dioxide into oxygen, but also consumes a considerable part of the oxygen and emits a large amount of carbon dioxide.
Although marine ecology still exists, and seaweed and other marine plants can convert some carbon dioxide, without sunlight, even seaweed cannot carry out photosynthesis, and soon the ocean will fall into an anoxic crisis before the land.
Without oxygen, fish in the ocean will die in large numbers, and the marine ecology will collapse.
As for land, previous global fires have exterminated a considerable part of terrestrial life and burned most of the plants. The terrestrial ecology had collapsed at that time.
After the dual collapse of the ocean and land ecosystems, the oxygen cycle in the atmosphere will no longer exist, and the oxygen content in the atmosphere will further decrease.
Under normal circumstances, the oxygen content in the atmosphere is 20.9%. If the oxygen content is less than 18%, the human body will begin to experience a hypoxic reaction.
This is just like altitude sickness. At first, your breathing may be slightly faster, your heartbeat and blood pressure will rise, and you will feel tired easily. People with stronger bodies may not even feel anything at all.
But as the oxygen content further decreases, obvious fatigue will follow, concentration will begin to decline, thinking will become confused, and even loss of consciousness and coma will occur.
If the oxygen content continues to decrease, the human body will experience symptoms such as headache, tinnitus, dizziness, nausea, vomiting, and even death.
Originally, there were a large number of plants on the earth performing photosynthesis, and the oxygen content in the atmosphere was maintained at a relatively stable level.
But now that the ecosystem has collapsed, it is no longer possible to rely on self-regulation of the ecosystem to restore the oxygen content in the atmosphere before the sun shines on the earth again.
Fortunately, before the disaster occurred, mankind had three months to prepare. Although during that time, governments were mainly focused on how to prevent meteorites from falling, but this does not mean that countries were not prepared for the disaster. A plan for how to deal with it in the future. (End of chapter)
