Air pollution introduction,body parts, conclusion
Answers
Explanation:
INTRODUCTION
Air pollution occurs when harmful or excessive quantities of substances including gases (such as ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules are introduced into Earth's atmosphere. It may cause diseases, allergies and even death to humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Both human activity and natural processes can generate air pollution.
Indoor air pollution and poor urban air quality are listed as two of the world's worst toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.Outdoor air pollution alone causes 2.1 to 4.21 million premature deaths annually.According to the 2014 World Health Organization report, air pollution in 2012 caused the deaths of around 7 million people worldwide,an estimate roughly echoed by the International Energy Agency
CONCLUSION
The health of the public, especially those who are the most vulnerable, such as children, the elderly and the sick, is at risk from air pollution, but it is difficult to say how large the risk is. It is possible that the problem has been over-stressed in relation to other challenges in the field of public health.
As we have seen, there are considerable uncertainties in estimating both exposures and effects and their relationships. It may be, for example, that the effects of long-term exposure to lower concentrations of air pollutants could be more damaging to public health than short-term exposure to higher concentrations. For this reason alone, local authorities could take action to assess and improve local air quality. It is not sufficient to wait for an episode of severe air pollution and then try to deal with its effects.
Another reason for action on air pollution is that we do not know the contribution which exposure to air pollutants may make to deaths from, for example, heart disease. In many countries heart disease is a leading cause of death and even a small contribution from air pollution could mean a significant and important effect on public heath.
On an individual level, the risk to health from air pollution is very much smaller than that posed by active cigarette smoking or accidents. It is also true that healthy individuals are rather unlikely to be affected by exposure to the concentrations of outdoor air pollutants in many European countries on most days of the year. However, the old and the young, and especially those suffering from respiratory or heart diseases, are the groups who are most vulnerable to the effects of air pollution. It is only right that cost effective action should be taken to provide them with clean air, which The Times of 1881 described as "the first necessity of our existence."
Explanation:
Air pollution is caused by burning of fossil fuels in factories.
Burning of fossil fuels lead to the production of poisonous gases such aa CO and C02
CO is a dangerous gas which lead a man to death
C02 is a important gas in green house effect.
if this gas increases the rate of temperature increases which lead to global warming
