essay on Air pollution – Facts, Causes, Effects, Solutions
Free 750 words essay on Air pollution – Facts, Causes, Effects, Solutions for school and collage students.
Air pollution is considered to be the worst forms of pollution as pollution which is characterized by presence of toxic chemicals in the atmosphere. Human activities such as mining, fossil fuel burning, vehicular emission, construction, transportation, agriculture, etc., are responsible for a tremendous health hazard. Natural processes barely have a significant contribution in this menace. The pollutants are mostly in gaseous and solid forms. These predominantly are sulfur oxides, nitrogen oxides, carbon monoxide, carbon dioxide, particulate matter, volcanic organic compound, radioactive pollutants, and ammonia. Anthropogenic causes at a relentless pace and ignorance towards environmental degradation has exacerbated the problem.
Facts about Air Pollution:
- More than 92% of world’s population lives in places where the air pollution levels have reportedly exceeded safer limits as according to World Health Organization (WHO).
- Air Pollution is the reason for fourth largest threat to human health. The health risks include chronic lung problems, cardiovascular diseases, stroke, asthma, cancer, etc.
- 6% of all global deaths in 2012 as reported by WHO was from some air-pollution disease.
- 94% of all air-pollution related deaths occur in low- and middle-income nations. The biggest regional danger spots are Africa, Eastern Europe, India, China and the Middle East.
- The economic cost of air pollution was calculated at around $225 billion by the World Bank and Institute of Health Metrics and Evaluation (IHME).
- Beijing cough is a name given to a typical type of coughing disease in Beijing, China.
- More than 80% of lung diseases are caused by air pollution.
- A research from MIT has proven that around 13,000 British citizens die due to air pollution.
- The California Department of Education in the United States claims that asthma is the biggest cause of school absenteeism among children.
- Indoors air pollution is equivalent or even worse than outdoor pollution.

- The predominant cause is proven to be energy use and production. The burning of fossil fuel releases huge amount of noxious air in the atmosphere. Similarly, other anthropogenic activities contribute to the destructive loop. Climate change causing rise of surface temperature worsens the situation. It increases the allergenic air pollutants production. Factories and industrial activities emit colossal amount of carbon gases that depreciates the quality of air substantially on almost a perpetual basis.
- Agricultural activities are another big reason which produces ammonia and methane. Excessive use of insecticides and pesticides release harmful chemicals in the air.
- Manufacturing industries emit carbon monoxide, hydrocarbons, and organic compounds in the air.
- Mining operations are done through large equipment which release dust and chemicals during its operation.
- Carbon dioxide forms 80% of greenhouse gases which is typically responsible for rising sea levels, extreme weather, warmer oceans, heat related fatalities, and transmission of infectious diseases. Methane forms another 11% of the GHGs which cumulatively increase the temperature of atmosphere.
- The carcinogenic pollutants pose a terrifying health hazard. Elements mixed up in the air such as mercury, lead, dioxins, and benzene offer serious health risks. It can lead to short-term and long-term disorders where endocrine, reproductive, immune, and nervous system can get affected.
- Global warming is caused due to excessive air pollution which is responsible for melting of ice caps, displacement and rehabilitation issues, etc.
- Respiratory and heart related problems have become ubiquitous with the incessant rise in air pollution.
- Acid rain has started affecting humans and agriculture. The eutrophication condition is depleting natural water bodies.
- Depletion of ozone layer due to chlorofluorocarbons has been one of the most promising challenges before the international community as it is the ozone layer which protects earth from harmful ultraviolet radiations.

- Proliferation of public means of transportation is a pressing requirement that must be promoted or enforced across the world to reduce burning of fossil fuels. Metro rails, car-pooling, and other innovative methods of transportation needs to be discovered and implemented.
- Energy conservation is important as it would lead to lesser demand of production of electricity which in turn would reduce the burden of fossil fuel burning.
- Reuse, reduce and recycle must be incorporated as basic principles of existence.
- Promotion and usage of renewable energy sources is imminent as the fossil fuels would deplete in few more decades. Instead of excessive reliance on these polluting substances, alternative methods of electricity generation such as solar, wind, bioenergy, geothermal energy, etc., needs to be promoted.
- Industrialized nations must decrease their carbon footprint and help the low-income or developing countries with financial assistance and technology transfer in attaining their stipulated goals.
- Increase in carbon taxes, cutting down the production of gasoline, incentivization of clean energy resources, and investment in pollution free mechanisms are some immediate and unavoidable solutions.
