The biggest impression I have this year is the high temperature weather of more than 40 degrees in many places across the country, which has continued to this day. Some people not only want to ask why this situation occurs, but there was no such extreme climate more than 30 years ago. The root cause of this climate is simply the intensification of our human activities. I have been in Chongqing for more than two months, and the temperature has been maintained at around 39 degrees to 42 degrees. It has basically not rained during this period. There are even online reports that several unknown rivers in Chongqing have stopped flowing. This situation is unacceptable. imaginary. Chongqing is a second-tier big city in the country. Like many big cities in the south of the country, the closer you are to a big city, as long as you step out of the room, the heat wave will become higher and higher. The ground temperature can even reach 50 or 60 degrees. In fact, this is what big cities are like. The urban " heat island effect " caused by the large-scale development of cities.

In reinforced concrete cities, with a population of tens of millions and densely populated with reinforced concrete, the city absorbs a large amount of the sun's scorching heat, causing the urban temperature to run at a high level, which is very harmful to human survival. It is very disadvantageous. This disadvantage has been highlighted. In the future world, villages far away from cities are more suitable for human survival. If you still squeeze your head into the city, I don’t think it is a wise choice. There is a phenomenon in 2022. The number of people drowning due to playing in water continues to rise, especially in recent days, the rising water in a flood discharge ditch in Pengzhou caused many deaths. These are the results of risk spillover among urban people in high temperature environments. Various disadvantages and hidden dangers caused by ultra-high temperatures have emerged. Properly controlling the scale of urban development and rationally utilizing resources are related to human survival. We have lost more than we have gained, and it is irreversible. Everyone should be highly vigilant!
