The Risk of Air Pollution

According to The World Health Organization, air pollution is responsible for the world’s largest single environmental health risk. They say that seven million people died from exposure to air pollution in 2012, more than two times the number previously estimated in 2008. From a new report which shows that one in eight people around the world die from air pollution.

The rate of death is divided into indoor and outdoor air pollution following the list below

Indoor air pollution
34%- Stroke
26%-Ischemic heart disease
22%-  Chronic obstructive pulmonary disease (COPD)
12%- Acute lower respiratory infections in children
6%- Lung cancer

Outdoor air pollution
40%- Ischemic heart disease
40%- Stroke
11%- COPD
6%- Lung cancer
3%- Acute lower respiratory infections in children

They also says that the population die prematurely from those and most of them are in low-and middle-income countries in Southeast Asia and the western Pacific, where around half the world’s people cook and heat their homes using open fires and simple stoves. From the reports 4.2 million people who use coal and biomass fuels, such as wood, animal dung and crop waste die prematurely in 2012 and they link an additional 3.7 million deaths in urban and rural areas to outdoor air pollution.


Dr. Carlos Dora, who is an Environmental and Social Determinants of Health coordinator of WHO Public Health, said the cause of the death rate in the undeveloped and developing countries being larger than the developed ones is the latter have taken action about reducing air pollution during the past decade by using better engines, cleaner fuels more efficient energy technologies, reduction in the need for the use of energy, insulation of houses, etc. Clean energy, solar, wind, energy which does not use combustion is better than those that do use combustion. So those are the matter for the former to take action as quick as possible she also said that in most cases, healthier air pollution strategies will be more economical in the long run because health care costs will go down.
