Introduction: In recent days, air pollution has become increasingly severe across various regions… As of the time this post was written, more than 70 cities across the country are suffering from severe pollution, and the area affected by this heavy pollution has expanded to 620,000 square kilometers – accounting for a large portion of the habitable areas in the north. This proportion is continuing to increase. As professionals in the chemical industry, we cannot turn a blind eye to this situation. A battle between the natural environment and humanity is about to begin; clarity, freshness, health, harmony, nature, and environmental protection will be the key terms we need to focus on in the coming days. Topic: Focus on Fog Mai; post rationally. A thorough discussion on sea and rivers: talking about the formation and impacts of fog, as well as ways to alleviate or control it, and methods to eliminate fog. At present, there is no unified answer to this most challenging issue, nor are there any accurate data to explain the causes of fog. Therefore, everyone is free to analyze and understand it, to put forward reasonable opinions, conduct analyses and arguments, and offer their own suggestions. The purpose of these discussions is to help people gain a proper understanding of this environmental problem that threatens our health and well-being, to analyze the issues rationally, and to come up with suggestions for mitigating and eliminating fog. 【Serious Reminder】All speakers are asked to post in a rational manner. The opinions expressed here represent only the individual views of the speakers and do not reflect the stance of the forum. Posts containing rumors, calls for accountability, attacks, insults, reports, or any other form of inappropriate content are not permitted. If debate is needed, it can be conducted in an hypothetical manner. Examples of opinions: [Opinion 1] For winter heating, the large amount of coal ash generated by coal-fired stoves and boilers causes pollution, leading to an increase in PM2.5 levels in the atmosphere. Analysis omitted... [Recommendation 1] It is recommended to improve environmental protection facilities and use bituminous coal for heating. 【Viewpoint 2】There are too many barbecue stalls, which leads to an increase in atmospheric PM2.5 levels. 【Suggestion 2】 【Viewpoint 3】 The smoke generated by burning straw leads to an increase in atmospheric PM2.5 levels. 【Suggestion 3】 【Viewpoint 4】 Vehicle exhaust, 【Suggestion 4】 【Viewpoint 5】 Vegetation destruction, 【Suggestion 5】 【Viewpoint 6】 Sandstorms, 【Suggestion 6】 【Viewpoint 7】 Exhaust gases from chemical production, 【Suggestion 7】
One thing is clear: ever since the emergence of Fog Mai, sandstorms in the north are no longer seen
A few days ago, I saw a post about fog, saying it was mainly caused by urbanization. I think it’s mainly due to the rapid development of heavy industry and the surge in the number of cars. Actually, this is a positive phenomenon; it’s a stage that our country must go through, so there’s no need to worry too much. We can’t stay in an agricultural era forever, and smog will eventually become a thing of the past, but that will only happen once we reach a more developed level. The complaints from the chemical industry right now are just the beginning of the transformation in heavy industry. It seems unlikely that we’ll ever be able to get rid of smog during our lifetime; perhaps future generations will be able to see blue skies again.:lol
I think it’s mainly due to the destruction of vegetation; look, Guizhou has a high coverage rate and good air quality!
This is a fascinating question: without fog, are there no sandstorms? Still, I like sandstorms; they have the roughness of the north, while fog makes things unclear and confusing.
Rapid development has its advantages and disadvantages; it’s like sweeping a yard – if you sweep too quickly, more dust is generated.
I agree with and support your view that the destruction of vegetation is primarily due to the rapid expansion of cities. We can carefully examine and compare the size of our city over the years using Google Earth, to see how much wasteland has been converted, how much of it has been utilized, what it was originally, and what it is now. The rapid expansion of cities benefits the real estate industry and development areas, but at the cost of the original farmland, wasteland, and the vegetation that once covered those lands. At present, many of these development areas are merely expanding; they have not yet been fully developed, nor has the original vegetation coverage been restored.
To address this issue, I suggest that after the park planning is completed, the surrounding area should be landscaped first to restore vegetation coverage, before any construction takes place.
I think now that there are no real drawbacks to acting quickly; otherwise, if we lag behind in terms of industrialization, we’ll always be bullied by others. Without today’s rapid development, what would happen to us if it were the United States and Japan who were in charge? Moreover, the initial expansion of capital economies was always rapid and uncontrolled, and it couldn’t be brought under control. Just look at this year – when GDP reaches 6.5, people already find it hard to cope; if it drops to 1 or 2, everyone would go crazy from poverty. . . . :lol
The haze used to be very severe, but we have wind; once the wind blows, sandstorms occur and the haze is covered up. After the construction of the forest belts in the three northern regions, the northwestern winds weakened, sandstorms disappeared, but we still didn’t have enough food, and haze emerged as a result.
Viewpoint 4: Vehicle exhaust – Why is there fog even though there are restrictions on vehicle use? It’s not really the high number of cars that’s to blame; the real problem is the poor quality of gasoline! The two oil giants monopolize gasoline; they only know how to raise prices, not improve quality! Whose fault is it?
