Although the rapid development of science and technology has brought many benefits to mankind and made people’s quality of life higher and higher, science and technology have also brought a crisis to the survival of mankind. The rapid development of industry has caused a large amount of waste gas, waste water and other pollutants to be discharged into nature, making the earth’s ecological environment continue to deteriorate, and bringing more and more serious impacts on human survival.
In addition to the environmental pollution caused by industrial development, another more terrifying potential crisis we have to consider is nuclear war. With the advent of technology, the mode of warfare is constantly changing, from the past cold weapon era to the hot weapon era.
In the middle of the last century, the United States dropped two atomic bombs on Japan. The huge explosive power and destructive power directly made Japan choose to surrender unconditionally. This is the first time that mankind has seen the terrible power of nuclear weapons, which can directly overwhelm a country. Therefore, after World War II, countries in the world are actively studying nuclear weapons as the ultimate strategic weapon to ensure the security of a country.
The emergence of nuclear weapons stems from the mass-energy equation proposed by Einstein. It is a weapon that uses the huge energy released instantaneously by the self-sustaining nuclear fission or fusion reaction to produce explosive effects and has the effect of mass destruction. It mainly includes fission weapons and nuclear fusion. The representative of nuclear fission is the atomic bomb, and the representative of nuclear fusion is the hydrogen bomb.
Nuclear weapons have always been recognized as the most destructive weapons all over the world, and they will cause deadly harm to the ecological environment of the earth and mankind. The reason why nuclear weapons are terrible is not only the huge shock wave produced by their explosion, but also the rapid and rapid spread of nuclear radiation, which can cause huge damage to the environment and living organisms, and this damage is long-term, and the impact can be up to For hundreds of years.
It is precisely because of the terrifying nature of nuclear weapons that they will not be used lightly, but only serve as a strategic deterrent. But let’s not forget that human beings are a very militant race. Since the formation of human civilization for more than 6,000 years, wars have never stopped. I don’t know how many wars have occurred, especially since modern times. There have been two world wars.
Einstein once had a prophecy: “I don’t know what weapons humans will use in World War III, but I know that weapons used by humans in World War IV will be wooden sticks and stones.” Einstein’s prediction actually tells us that once World War III explodes, there is a high probability that it will eventually evolve into a nuclear war, thereby destroying human science and technology civilization.
According to relevant data, up to now, the total reserves of nuclear weapons in countries around the world are as high as 13,000. Once they explode, their power is enough to destroy the earth’s ecology dozens of times. Of course, so many nuclear weapons are not enough to destroy the earth, but they can bring terrible biological extinction to the earth.
I believe everyone can think of the terrible nuclear war, so someone raised a question: If a nuclear war breaks out, how can we save ourselves? We don’t want the outbreak of nuclear war to destroy science and technology, but there is no absolute truth. Once something we worry about happens in the future, how can we save ourselves? There are actually three things to keep in mind.
1. Trenches with water sources
Within the first few hours of a nuclear weapon explosion, the explosion will produce a powerful shock wave, which will release powerful energy to destroy everything on the surrounding surface. As long as it is a person or thing that breaks through the surface, it will be crushed and destroyed within the range of impact of the shock wave of the nuclear explosion.
If we are within the shock wave of a nuclear explosion and want to avoid damage, we need to hide below the surface in time. A trench with a water source would undoubtedly be a good place. First, the trench is below the surface, and there is enough thick ground to form a bunker to withstand the blast wave.
At the same time, there may be water sources in the trenches, which is conducive to sufficient water supply during the period of avoidance. We must know that human beings cannot survive without water. Once water is lacking, it will cause serious harm to human health. Therefore, in nature, an ideal place to avoid the shock wave of a nuclear explosion is a trench.
2. A solid subway station
I believe my friends are familiar with subway stations. Nowadays, many first- and second-tier cities have built subway stations, which have become an important means of transportation for people to travel in the city. Subway stations are built in relatively deep underground, and the construction standards are very strict, and they are basically carried out to resist nuclear explosions.
More importantly, the subway station is wide enough to accommodate more people. The subway station has strong shock, pressure, and waterproof functions. It can also completely block nuclear radiation damage after nuclear explosions. It also has good ventilation functions and some equipment is relatively complete. For densely populated cities, this is definitely a good choice to avoid nuclear explosions.
3. Basement or underground garage
When we had a nuclear explosion, we stayed at home or in the community and did not have enough time to hide in the subway station, so we need to choose a place of refuge based on the principle of being nearest. In our home or community, the basement or underground garage is undoubtedly a good choice.
There is basically an underground garage in each community, and there is also a basement at the bottom of the building. These two places are the first choices for the residents. Whether it is an underground garage or a basement, there is a good confined space, which can provide us with an excellent hiding place to avoid nuclear explosions, and can temporarily avoid the huge damage caused by the initial nuclear explosion.
Of course, in addition to the above three places, there are also some places that can also be used to avoid nuclear explosions, such as air-raid shelters, but the location of air-raid shelters is often relatively hidden, and ordinary people rarely know it, and air-raid shelters are not casual. Open to the outside world. Therefore, for ordinary people, subway stations, underground garages and basements are the best choices.
