Air pollution has lots of effects but I think the thing we worry about most is the shortening of life and reducing people’s life expectancy.
forty years ago, we were thinking about this issue and began what was called a six-city study and that study showed that people living in more polluted cities had shorter life expectancy who increased respiratory problems but also through increased heart attacks increased strokes.
And as air quality has gotten better in those communities, we’ve seen that those people are living longer and have better health.
Air pollution comes from combustion and we’re burning fuels for produce energy to produce heat to drive our cars.
All the things we think about in terms of our day to day life contribute to this Air pollution.
Global warming are also causing the air pollution in developing countries
Improvements in air quality over the past 40 years in the United States and Europe and other developed countries this has been due to controls on automobile emissions, reductions in emissions from power plants and other industries.
we can see improvements in health in terms of extended life expectancy, reduced asthma attacks, reduced hospital admissions.
A new study from the University of British Colombia found that more than 5.5 million people will die prematurely each year because of air pollution.
More than half the deaths will occur in China and India, two of the fastest growing economies.
Air pollution is a mixture of fine particles ,gases, ozone, tobacco, smoke and other substances according to the National Institute of Environmental Health Sciences.
Heart disease asthma and other lung diseases have been linked to air pollution.
lead study author said in a press release: “Air pollution is the fourth highest risk factor for death globally and by far the leading environmental risk factor for disease. Reducing air pollution is an incredibly efficient way to improve the health of a population.”
The new study was presented at the 2016 annual meeting of the American Association for the Advancement of Science.
