Air pollution
Polluted environments, especially visible air, have become an integral part of our lives. Everybody knows that the particles and dust of different shapes in the air are harmful to us. But we don't really care about air pollution because we don't see the harmful activity of them directly. So let's take a look at the statistics to understand exactly how harmful air pollution is. According to a 2015 study, the number of deaths due to air pollution in the world is more than 3 million every year. According to BBC News on 6 November 2019, 7 million people die of premature age every year in the world due to air pollution. In other words, more than 19 thousand 189 people are dying due to air pollution every day. This is more than the number of deaths from malaria or AIDS each year. More surprisingly, the survey was conducted in high- and middle-income countries around the world, where a certain amount of money is spent each year to maintain air quality. If the situation is so dire only in developed and middle-income countries, then the situation in low-income countries will be more serious.
To
find out, environmentalist Jennifer Barney and her team were decided to conduct
a survey of countries in the sub-Saharan region south of the Sahara Desert in
Africa. Due to a lack of adequate data, these areas could not be brought under
study earlier. For this, they chose 30 countries south of the Sahara Desert.
From the survey, they discovered some alarming information. According to their
estimates, in 2015, about 44 lakh 9 thousand children died due to air
pollution. This means that air pollution is responsible for 22 percent of child
deaths in these regions. According to Joss Leleveld, director of the Max Planck
Institute of Chemistry, the death toll in high- and middle-income countries
alone is more than 3 million, while in low-income countries the number will
rise alarmingly.
The air in Delhi, India is the most polluted in the world. Delhi is now described as a 'gas chamber'. Five of the six most polluted cities in the world are in northern India. According to a Greenpeace survey last year, 22 of the world's 30 most polluted cities are in India.

Air
pollution usually has the opposite effect of household improvement. But the
data obtained has been seen. Although the household situation in sub-Saharan
countries has gradually improved over the last 15 years, the adverse effects of
air pollution on households have not diminished. Scientists attribute this
deadly effect of regional winds to the concentration of particulate matter in
the air. Particles with a radius of 2.5 micrometers or smaller are considered
the most harmful to our bodies. It has been found that the amount of this
particle per cubic meter is 2 to 25 micrograms. Increasing the amount of these
particles by 10 micrograms per cubic meter has resulted in a 9 percent increase
in infant mortality.

Studies
further show that air pollution is not the only cause of death from respiratory
infections. This is because the death rate from air pollution in those areas is
higher than the death rate from respiratory infections. In other words, air
pollution is affecting our health in a different way than just the respiratory
system. But what kind of effect? That is still unknown to scientists. According
to scientist Josie Leleveld, there is a need to quickly diagnose other aspects,
not just the effects of wind on the system, which will initially pave the way
for survival from this harmful effect.
In addition, their research has only been able to establish a relationship between air pollution and infant mortality rates. But they have not yet been able to ascertain exactly how many children are dying from the effects of air pollution. Jennifer Burney, the group's chief environmental scientist, said the exact number of infant deaths could not be determined, but the relationship showed that reducing air pollution could reduce the rate by at least 22 percent.
This study is sufficient to indicate the
severity of air pollution as well as to act as a stimulus to take the necessary
initiatives for air purification. It is good for mankind to take urgent action
to purify the polluted air which is indirectly constantly damaging..
