When it comes to the pain of smog, no country or region is more aware of this kind of skin pain than the "Mist". London's smog in 1952, killing tens of thousands of people in just two months!

 

In order to avoid this horrible "invisible killer", Londoners who love social and outdoor sports have to close their doors and completely separate themselves from the outside world. What is desperate and frightening is that these efforts seem to have been lost. The streets were full of fog and even invaded the room - the court had to interrupt the case because the witness could not find a way to the court; the theater had to cancel the show because the audience and the actors could not see each other... Even when sitting at home, people can't see their toes. Under the poisonous fog, a large number of people feel difficulty breathing, and coughing can be heard everywhere in London. According to the official release of London, the number of people who died in the four days of thick fog reached 4,075. It is generally believed that this is an underestimation of the actual number of deaths. After two months, more than 8,000 people have lost their lives.

 

The toxic fog is rampant. In fact, most of the world's major developed industrial countries have experienced history. The United Kingdom has experienced, the United States has experienced... and now, it is our turn. What is worrying is that our national "smog war" seems to have just begun. In addition to relying on government governance, what can our people do, besides going out wearing masks and relying on air purifiers at home, what self-help can they do? How long does it take to fight the war? CCTV's "Focus Interview" interviewed Wang Yuesi, a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, last year. He clearly stated: "The haze process cannot be solved in a short period of time... three years and five years or even ten years. This is unrealistic. Kind of thoughts. "Even the most professional and authoritative people are so determined that it really makes people collapse.

 

Every time the smog is serious, our experts have emphasized that the fog and the sky should close the doors and windows and minimize the outing. However, I think it is almost impossible to think about it. Even if we are all locked up at home, even if a few families have the conditions to install a fresh air system, and have more money to buy more air purifiers, there is no way to fundamentally solve the gas exchange in all indoor spaces and the long-term closure of the portal. The problem of low oxygen is to know that for those who have respiratory diseases and cardiovascular and cerebrovascular diseases, hypoxia is terrible! For more ordinary families, the elderly and children without a fresh air system and without an air purifier may not be immediately ill, but it is impossible to ventilate the air for a long time without opening the doors and windows. Then, the doors and windows with anti-smashing function may be the first line of defense against effective cockroaches, and it is also the most energy-saving and long-lasting anti-mite protection measure for houses.
