At present, environmental protection has become something we must do, because the environment on the earth is being threatened.

Now, we know that the earth has begun to warm and the ice in cold places has begun to melt. The changing water makes the water level higher and higher, and many coastal countries are submerged. More land desertification and natural disasters are coming, which makes our life less carefree.

First of all, we should start from the side.

Large areas of forests are constantly being cut down and automobile exhaust is constantly being emitted? These will directly affect our lives first, because they make us "afraid to breathe". Therefore, the best way to solve these problems is to drive less and ride more bicycles. Besides, cycling is also good for your health! . But although it has been said all the time, and it has been said more than once, why are there still so many cars on the road? So, this method is really, a little unrealistic.

The simplest thing is to plant trees. Trees are good friends of human beings. They can help people do many things, such as purifying the air, and so on. So, all kinds of trees, this method is very practical!

2. The air in more than 20 cities in China is moderately polluted.

Moderate to severe air pollution occurred in Beijing, Tianjin, Taiyuan, Luoyang, Xi 'an, Tangshan, Baoding, Langfang, Lanzhou and Xianyang 1 1 day, affecting Beijing, Tianjin, Hebei, Henan, Shandong, Shanxi, Shaanxi, Gansu, Ningxia, Xinjiang and other provinces, cities and autonomous regions.

China National Environmental Monitoring Center, together with relevant experts, analyzed that from June 5438+0 1 day to June 5438+03, a moderate to severe pollution process may occur in the south-central part of Beijing-Tianjin-Hebei region. It is predicted that the affected cities include Beijing, Shijiazhuang, Baoding, Tangshan, Heze, Shandong, Taiyuan and Jinzhong.

The monitoring shows that the air in Lanzhou, Gansu, Xianyang, Shaanxi and Zhongwei, Ningxia was seriously polluted at 8: 00 on June 5438+0/kloc-0, and the air quality index in Lanzhou reached or exceeded 500. The air in Tangshan, Baoding and Langfang in Hebei, Qingyang in Gansu and Kashgar in Xinjiang is heavily polluted. The air in 20 cities including Beijing, Tianjin, Cangzhou, Taiyuan, Luoyang, Anyang, Tai 'an, Xi 'an and Pingliang is moderately polluted. The air in more than 40 cities such as Shijiazhuang, Yantai, Weihai, Penglai, Rizhao, Leshan, Baoji, Hohhot, Anshan, Liaoyang and Korla is lightly polluted.

3. Why did the smog sweep the six northern provinces recently?

Affected by a wide range of calm and foggy weather, heavy polluted weather has recently appeared in northeast China, north China and east China. From Harbin, it was transmitted to the south-southwest direction along the Harbin-Dalian line, until it reached Shandong Peninsula, Jiangsu and northern Anhui, affecting more than 30 cities in 6 provinces and regions, spanning 1600 kilometers, and many cities "broke the table", with heavy pollution and wide influence.

In order to find out the cause of pollution, the Ministry of Environmental Protection organized a consultation meeting. According to experts' analysis, the main reason for this round of heavily polluted weather is the excessive emission of air pollutants, among which coal-fired heating, industrial and motor vehicle emissions are the "culprit". In addition, unfavorable meteorological conditions are also important incentives.

Chai Fahe, a researcher at china environmental science Research Institute, said that the process of extreme pollution in winter in Northeast China has occurred for four consecutive years. The large-scale pollution process in Northeast China and East China started from June 5438+065438+1October 3 -4 in Harbin, Suihua and Daqing, Heilongjiang. Heavy pollution mainly comes from local coal-fired heating and biomass burning emissions in winter, which is the "culprit" leading to regional heavy pollution. On the afternoon of the 5th, affected by the northeast air flow, the polluted air mass continued to transmit to the south-southwest direction, passing through Changchun and Shenyang to Dalian, crossing Bohai Bay to Shandong Peninsula, and affecting Jiangsu and northern Anhui on the morning of the 6th. The long-distance transmission of polluted air mass, coupled with the contribution of local coal burning, industry and motor vehicle emissions, is the reason for severe or even serious pollution in many cities in Jilin, Liaoning, Shandong, Jiangsu and Anhui. The impact of PM2.5 concentration in some cities may be as high as 30-50%.
