Air pollution kills almost 3.3 million people a year. Scientists say that by 2050 this number will double. Conclusions are made from the calculation of the amount of content in the air of solid matter particles, abbreviated - PM 2.5. The figure here denotes the particle diameter in microns. These particles are contained in soot, smoke and exhaust gases, causing long-term health problems, such as asthma and chronic lung diseases.
Unfortunately, the level of air pollution for today is still of little concern to the governments of most countries on the world map. Life expectancy in some cities is decreasing from year to year - but the local population, usually, has nowhere to go. Today, the leaders of the "air anti-rating" are those 7 cities in the world where there is literally almost nothing to breathe.
Lucknow
India
Lucknow, a town in northern India, begins our list. People here breathe a terrible mixture of exhaust fumes and factory waste. A huge number of vehicles, almost not regulated by law, exacerbates the problem.
Khorramabad
Iran
One of the most densely populated cities of Iran, Khorramabad is the center of agriculture for the whole country. Probably, this is the main reason why experts find local air almost unsuitable for breathing. The death rate is almost 3.5 times higher than the national average.
Rawalpindi
Pakistan
Rawalpindi is a sister city of Pakistan's capital Islamabad. The lack of a coherent system of public transport has led to the collapse of the production and operation of private cars. As a result, the amount of exhaust gas here goes beyond all reasonable limits. However, already at the end of this year the government of the country is going to start construction of the underground, that should somehow solve the problem.
Raipur
India
This city is located in central India: it is not as large as the previous policies from our list, but the level of air pollution here is off scale. The reason for this is that researchers see several city-forming enterprises for the production of steel and aluminum.
Gwalior
India
The abundance of Indian cities in this listing should alert the lovers of a healthy holiday in this region. Gwalior is so polluted that even the locals try to escape from here with all their might. The government of the country does not take any measures to improve the situation.
Patna
India
Patna, the second largest city in the eastern part of India, is one of the main agricultural centers of the country. The irrational use of electricity, the abundance of private transport and the number of industries at the periphery make Patna's air almost unsuitable for breathing.
Beijing
China
And finishes our list of majestic Beijing. This photo was taken in February last year - and most of the time, the air here looks like this.
