1. Green environmental protection

Nowadays, environmental protection has become something we must do, because the environment on the earth is now under threat.

Now, we know that the earth has begun to warm, and the ice in cold places has begun to melt, turning into water that makes the water level higher and higher, flooding many coastal countries. More land becomes desertified and natural disasters continue to strike, making our lives no longer so carefree.

First of all, we must start from around us.

Large tracts of forest are being continuously cut down, and car exhaust is constantly being emitted? These will directly affect our lives first, because they make us "dare not breathe." Therefore, the best solution to these problems is to drive less and ride a bicycle more. Moreover, riding a bicycle is also very good for your health! But even though I keep saying this, and I say it more than once, why are there still so many cars on the road? Therefore, this method is really not practical.

The simplest thing is to plant trees. Trees are good friends of mankind. They can help mankind with many things, such as purifying the air, etc. Therefore, it is very practical to plant more trees!

2. Moderate air pollution occurs in more than 20 cities in China

Beijing, Tianjin, Taiyuan, Luoyang, Xi'an, Tangshan, Baoding, Moderate to severe air pollution occurred in Langfang, Lanzhou, Xianyang and other places on the 11th, affecting Beijing, Tianjin, Hebei, Henan, Shandong, Shanxi, Shaanxi, Gansu, Ningxia, Xinjiang and other provinces, municipalities and autonomous regions.

The China Environmental Monitoring Center, together with relevant experts, believes that from the 11th to the 13th, a moderate to severe pollution process may occur in the central and southern parts of the Beijing-Tianjin-Hebei region of China. It is predicted that the affected cities include Beijing, Shijiazhuang, Baoding, Hebei, and Tangshan, Shandong Heze, Shanxi Taiyuan, Jin and other cities.

Monitoring shows that at 8:00 on the 11th, the air in Lanzhou, Gansu, Xianyang, Shaanxi, and Zhongwei, Ningxia was seriously polluted, with the air quality index in Lanzhou reaching or exceeding 500. Air pollution is severe in Tangshan, Baoding and Langfang in Hebei, Qingyang in Gansu and Kashgar in Xinjiang. Twenty cities including Beijing, Tianjin, Cangzhou, Taiyuan, Luoyang, Anyang, Tai'an, Xi'an, Yan'an and Pingliang have moderate air pollution. More than 40 cities including Shijiazhuang, Yantai, Weihai, Penglai, Rizhao, Leshan, Baoji, Hohhot, Anshan, Liaoyang and Korla have mild air pollution.

3. Why has haze swept across six northern provinces recently?

Affected by large-scale calm and foggy weather, many places in Northeast my country, North China and East China have recently experienced haze. Heavy pollution weather. Starting from Harbin, it travels south-southwest along the Harbin-Dalian line to Shandong Peninsula, Jiangsu and northern Anhui, affecting more than 30 cities in 6 provinces and regions, spanning more than 1,600 kilometers. Many cities are "exploding" and have serious pollution levels. , wide range of influence.

In order to clarify the causes of pollution, the Ministry of Environmental Protection organized a consultation meeting. Expert analysis believes that the main cause of this round of heavy pollution is excessive emissions of air pollutants, including coal-fired heating, Industrial and motor vehicle emissions are the main culprits. In addition, adverse meteorological conditions are an important factor.

Researcher Chai Fahe of the Chinese Academy of Environmental Sciences said that the large-scale extremely heavy pollution weather process that has occurred in Northeast China in winter has occurred for four consecutive years. The large-scale pollution process in Northeast and East China began in the Harbin, Suihua and Daqing areas of Heilongjiang Province on November 3rd and 4th. The heavy pollution mainly originated from local coal-fired heating and biomass burning emissions in winter, which led to regional The "culprit" of large-scale heavy pollution. On the afternoon of the 5th, affected by the northeasterly airflow, the polluted air mass continued to travel south-southwest, passing through Changchun, Shenyang and Dalian, crossing the Bohai Bay and reaching the Shandong Peninsula, and affected the northern areas of Jiangsu and Anhui on the morning of the 6th. The long-distance transmission of polluted air masses, superimposed on the contribution of local coal burning, industry and motor vehicle emissions, is the reason for severe or even severe pollution in many cities in Jilin, Liaoning, Shandong, Jiangsu and Anhui. The PM2.5 concentration in some cities is affected by The impact of contaminated air mass transport may be as high as 30-50%.
