In Europe, more than 400,000 people die each year, and in India, 62,000 die prematurely from air pollution.
The World Health Organization (WHO) has reported that 92 percent of the world is affected by air pollution, warning that more than six million people die each year.

Is there a solution for fine dust?
I have studied the definition of fine dust, its effect on human body, and global trends.

Fine dust and its causes
Dust is divided into fine dust and ultrafine dust depending on particle size.
The World Health Organization (WHO) defines fine dust as dust less than 10 micrometers (㎛) in diameter and ultrafine dust in diameters less than 2.5μm.
The causes of fine dust vary.
Some fine dusts occur naturally through forest fires and dusts.
However, most are known to burn fossil fuels such as petroleum and coal, or air pollutants from automobile exhaust gases.

How dangerous
Fine dust particles usually include metals, nitrates, sulphates, tire rubber, soot, and the like.
These foreign substances are absorbed into the lungs through the bronchi and are known to cause respiratory diseases.
Typically, ultrafine dust and fine dusts cause pneumonia by neutralizing antibodies against bacterial pathogens.
It is also absorbed into the blood vessels, causing stroke, heart disease, and so on.
Heart disease and lung disease caused by soot are known to some extent.
However, recent studies have shown that fine dust can damage the liver, spleen, central nervous system, brain, and even reproductive organs that are not directly associated with the respiratory tract.
Children are the most vulnerable to fine dust and air pollution. According to a major study conducted over a six-year period, children living in air-polluted cities have up to 10% less lung capacity than normal people.
Such a lung function abnormality lasts forever.
Nine out of ten are at risk.
In 2016, WHO announced that more than 92% of the world's population is affected by air pollution.
It also estimates that more than six million people die each year.
Separately, UNICEF has reported annual deaths from air pollution of 600,000 children around the world.
Countries with particularly high levels of air pollution are located in major South Asian and African regions.
These countries are still burning wood or using solid fuels, such as animal feces, to keep their homes warm and warm, and the "domestic air pollution" caused by diseases and mortality is significantly higher than in other countries.
Could it be better?
The correct answer is not irrelevant to money. WHO Carlos Dora said in an interview with The Associated Press that there is polarization in air pollution.
"The wealthy nations are getting better in the air."
"Poor countries are getting worse, it's a reality these days."
As can be seen from the map above, the levels of air pollution in developed countries are relatively lower than in developing countries.
China, which has the sixth highest pollution-related mortality rate in the world, is relatively rich, but is suffering from pollution caused by excessive industrialization.
India also has a fine dust level that is 90 times higher than the WHO standard, and 622,000 people die prematurely each year due to air pollution-related diseases.
The situation in Europe is not good. Air pollution in Europe is heavily influenced by the use of diesel fuel and farming methods that produce ammonia and methane.
According to the data, Turkmenistan was the country with the highest air pollution-related mortality rate.
Tajikistan, Uzbekistan and Afghanistan, followed by Central Asia and the Middle East.

What are the main causes of fine dust in Korea?
Dust from China is considered as a major cause of fine dust in Korea.
A survey by the Seoul Environment Union, a civic group, cited the influences of neighboring countries such as China as a major factor.
But the results of the Ministry of Environment were slightly different.
The Ministry of Environment analyzed the air quality of Seoul in cooperation with NASA last year, and found that the contribution rate of fine dust was 52% in Korea and 48% in foreign countries.
As a result of the survey, the major sources of fine dust in the nation were the factories and factories (38%), followed by construction and ship (16%) and power plants (15%).
Old diesel vehicles (11%) were also identified as the main cause of fine dust emissions.
Lack of long-term fundamental measures?
Last year, the South Korean government announced a roadmap to reduce the amount of fine dust emissions by 30% by 2022, by jointly discussing the "fine dust management comprehensive measures" jointly with the Ministry of Environment and other ministries last year.
Comprehensive countermeasures include dealing with fine dust with the top level agenda between Korea and China, strengthening fine dust environment standards and preparing countermeasures against key emission sources.
It is also considering ways to significantly strengthen the standards of large-scale emissions plants such as steel and oil. However, some point out that the fundamental measures are lacking.
Park, Young - Sun, with Democratic lawmakers on the 15th his Facebook noted the fine dust reduction measures of emergency in Seoul and criticized "as prescribed refrain from asking for driving, the fine dust of Seoul not to fundamentally improve."
"Air quality issues are not a solution to finding a temporary prescription, but a sustainable, everyday countermeasure," he said. "It is very urgent for me to get out of blaming China for the exact cause."
Hwang Seong-hyun, head of the policy team of the Korean Federation for Environmental Movement, pointed out that "the emergency action for the fine dust in the city of Seoul has already been issued in a polluted situation," he pointed out.
"In the long run, we need to reduce the number of vehicles in the city," he said in an effort to reduce secondary dust from the road.
