Essay on Air Pollution – Earlier the air we breathe in use to be pure and fresh. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases . Moreover, the rapidly increasing human activities like the burning of fossil fuels, deforestation is the major cause of air pollution.

How Air Gets Polluted?

The fossil fuel , firewood, and other things that we burn produce oxides of carbons which got released into the atmosphere. Earlier there happens to be a large number of trees which can easily filter the air we breathe in. But with the increase in demand for land, the people started cutting down of trees which caused deforestation. That ultimately reduced the filtering capacity of the tree.

Moreover, during the last few decades, the numbers of fossil fuel burning vehicle increased rapidly which increased the number of pollutants in the air .

Causes Of Air Pollution

Its causes include burning of fossil fuel and firewood, smoke released from factories , volcanic eruptions, forest fires, bombardment, asteroids, CFCs (Chlorofluorocarbons), carbon oxides and many more.

Besides, there are some other air pollutants like industrial waste, agricultural waste, power plants, thermal nuclear plants, etc.

Greenhouse Effect

The greenhouse effect is also the cause of air pollution because air pollution produces the gases that greenhouse involves. Besides, it increases the temperature of earth surface so much that the polar caps are melting and most of the UV rays are easily penetrating the surface of the earth.

Air Pollution Essay: Understanding and Solving the Crisis

• Air Pollution Essay

Essay on Air Pollution

Environmental changes are caused by the natural or artificial content of harmful pollutants and can cause instability, disturbance, or adverse effects on the ecosystem. Earth and its environment pose a more serious threat due to the increasing pollution of air, water, and soil. Environmental damage is caused by improper resource management or careless human activities. Therefore, any activity that violates the original nature of the environment and leads to degradation is called pollution. We need to understand the origin of these pollutants and find ways to control pollution. This can also be done by raising awareness of the effects of pollutants.

Air pollution is any physical, chemical, or biological change in the air. A certain percentage of the gas is present in the atmosphere. Increasing or decreasing the composition of these gasses is detrimental to survival. This imbalance in gas composition causes an increase in global temperature which is called global warming.

Introduction to air pollution 

The Earth and its environment are facing a serious threat by the increasing pollution of the air, water, and soil—the vital life support systems of the Earth. The damage to the environment is caused by improper management of resources or by careless human activity. Hence any activity that violates the original character of nature and leads to its degradation is called pollution. We need to understand the sources of these pollutants and find ways to control pollution. This can be also done by making people aware of the effects of pollutants. 

Air with 78% Nitrogen, 21% Oxygen, and 1% of all other gasses support life on Earth. Various processes take place to sustain the regular percentage of gasses and their composition in general. 

Atmospheric pollution can have natural sources, for example, volcanic eruptions. The gaseous by-products of man-made processes such as energy production, waste incineration, transport, deforestation and agriculture, are the major air pollutants.

Although air is made up of mostly Oxygen and Nitrogen, mankind, through pollution, has increased the levels of many trace gasses, and in some cases, released completely new gasses to the atmosphere. 

Air pollution can result in poor air quality, both in cities and in the countryside. Some air pollutants make people sick, causing breathing problems and increasing the likelihood of cancer. 

Some air pollutants are harmful to plants, animals, and the ecosystems in which they live. Statues, monuments, and buildings are being corroded by the air pollutants in the form of acid rain. It also damages crops and forests, and makes lakes and streams unsuitable for fish and other plant and animal life. 

Air pollution created by man-made resources is also changing the Earth’s atmosphere. It is causing the depletion of the ozone layer and letting in more harmful radiation from the Sun. The greenhouse gasses released into the atmosphere prevents heat from escaping back into space and leads to a rise in global average temperatures. Global warming affects the average sea-level and increases the spread of tropical diseases.

Air pollution occurs when large amounts of gas and tiny particles are released into the air and the ecological balance is disturbed. Each year millions of tons of gasses and particulate matter are emitted into the air. 

Primary air pollutants are pollutants, which are directly released into the air. They are called SPM, i.e., Suspended Particulate Matter. For example, smoke, dust, ash, sulfur oxide, nitrogen oxide, and radioactive compounds, etc.

Secondary Pollutants are pollutants, which are formed due to chemical interactions between the atmospheric components and primary pollutants. For example, Smog (i.e. Smoke and fog), ozone, etc.

Major gaseous air pollutants include Carbon Dioxide, Hydrogen Sulfide, Sulfur Dioxide and Nitrogen Oxide, etc.

Natural sources are volcanic eruptions, forest fires, dust storms, etc. 

Man-made sources include gasses released from the automobiles, industries, burning of garbage and bricks kilns, etc.

Effects of Air Pollution on Human Health

Air pollution has adverse effects on human health. 

Breathing polluted air puts you at higher risk of asthma.

When exposed to ground ozone for 6 to 7 hours, people suffer from respiratory inflammation.

Damages the immune system, endocrine, and reproductive systems.

A high level of air pollution has been associated with higher incidents of heart problems.

The toxic chemicals released into the air are affecting the flora and fauna immensely.

Preventive Measures to Reduce Air Pollution

We can prevent pollution by utilizing raw materials, water energy, and other resources more efficiently. When less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process, human health can be protected and economic wellbeing can be strengthened. 

There are several measures that can be adopted by people to reduce pollution and to save the environment.

Carpooling.

Promotion of public transport.

No smoking zone.

Restricted use of fossil fuels.

Saving energy.

Encouraging organic farming.

The government has put restrictions on the amount of fossil fuels that can be used as well as restrictions on how much carbon dioxide and other pollutants can be emitted. Although the government is attempting to save our environment from these harmful gasses, it is not sufficient. We as a society need to keep the environment clean by controlling the pollution of air.

FAQs on Air Pollution Essay: Understanding and Solving the Crisis

1. State the Causes of Air Pollution ?

The following are the causes of air pollution.

Vehicular pollution consisting of Carbon Monoxide causes pollution.

Emission of Nitrogen oxide by a large number of supersonic transport airplanes causes deterioration of the Ozone layer and also causes serious damage to the flora and fauna.

The release of Chlorofluorocarbons into the Stratosphere causes depletion of Ozone, which is a serious concern to animals, microscopic, and aquatic organisms.

Burning garbage causes smoke, which pollutes the atmosphere. This smoke contains harmful gases such as Carbon dioxide and Nitrogen oxides.

In India, brick kilns are used for many purposes and coal is used to burn the bricks. They give out huge quantities of Carbon dioxide and particulate matter such as smoke, dust that are very harmful to people working there and the areas surrounding it. 

Many cleansing agents release poisonous gases such as Ammonia and Chlorine into the atmosphere. 

Radioactive elements emit harmful rays into the air.

Decomposed animals and plants emit Methane and Ammonia gas into the air.

2. What Does Global Warming Mean?

Global warming is the gradual rising average temperature of the Earth's atmosphere due to the concentration of methane in certain toxic gasses such as carbon dioxide. This has a major impact on the world climate. The world is warming. The land and the sea are now warmer than they were at the beginning and temperatures are still rising. This rise in temperature is, in short, global warming. This temperature rise is man-made. The burning of fossil fuels releases greenhouse gasses into the atmosphere which capture solar heat and raise surface and air temperatures.

3. Name the Alternative Modes of Transport. In What Way Does it Help to Reduce Air Pollution?

Public transport could be an alternative mode of transport. Public transport like trains, buses and trams, can relieve traffic congestion and reduce air pollution from road transport. The use of public transport must be encouraged in order to develop a sustainable transport policy.

4. Mention other means of transportation! How can I help reduce air pollution?

Public transportation can be another mode of transportation. Public transport such as trains, buses and trams can reduce traffic congestion and reduce air pollution from road transport. The use of public transport and to develop sustainable transport policies should be encouraged. While one passenger vehicle has the convenience factor, other modes of transportation reduce travel costs, spend less time, reduce stress, improve health, and reduce energy consumption and parking. Other trips for work include walking/cycling, public transport, hybrid travel and transport.

5. What are the effects of pollution?

Excessive air pollution can increase the risk of heart attack, wheezing, coughing and difficulty breathing, as well as irritation of the eyes, nose and throat. Air pollution can also cause heart problems, asthma, and other lung problems. Due to the emission of greenhouse gases, the composition of the air in the air is disturbed. This causes an increase in global temperature. The damaging ozone layer due to air pollution does not prevent harmful ultraviolet rays from the sun, which cause skin and eye problems in individuals. Air pollution has caused a number of respiratory and heart diseases among people. The incidence of lung cancer has increased in recent decades. Children living in contaminated areas are more likely to develop pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution. When burning fossil fuels, harmful gases such as nitrogen oxides and sulfur oxides are released into the air. Water droplets combine with these pollutants and become acidic and fall as acid rain, which harms human, animal and plant life.

6. What is the solution to air pollution?

Production of renewable fuels and clean energy. The basic solution to air pollution is to get away from fossil fuels and replace them with other energies such as solar, wind and geothermal. The government limits the amount of fossil fuel that can be used and how much carbon dioxide and other pollutants it can emit. While the government is trying to save our environment from this harmful gas, it is not enough. We as a society need to keep the environment clean by controlling air pollution.

Air Pollution: Effects

Air refers to fluid found in the atmosphere. Air is an invisible, odorless and tasteless gas mixture found in the earth’s atmosphere. These characteristics of air enable it to mix with other compounds released to the atmosphere which have almost similar characteristics, but dangerous to human health. These compounds are referred to as pollutants. Therefore, air pollution can be defined as the introduction of foreign compounds other than the compounds that make up the air. Such compounds include gaseous chemicals in the form of gas or particulate in nature that cause harm to human health or other living organisms. These contaminants can also cause harm to the natural environment in the earth’s atmosphere (Liu and Lipták, p. 43).

The effects of air pollution on human health and the environment are detrimental and widespread. This is because every average person is supposed to take approximately 14 kg of air. This means that every time human beings breathe the air in the atmosphere they are prone to inhaling dangerous gaseous compounds. These poisonous compounds find their way in the human respiratory system, and this can have a great impact to the human body system. This also causes discomfort to most of the living things. People have the assumption that air pollution can only be found in places near industries or factories. This is because such companies and industries are known to the release carbon monoxide and Sulphur dioxide among other poisonous compounds. Though it is true that air pollution is likely to be prevalent in areas near such industries, one cannot dispute the fact that air pollution is not limited too such areas. Air pollution is found everywhere, both in doors and outdoors. Therefore, people should be warned and educated on the aspects that lead to air pollution and how to prevent the occurrence of the same (Liu and Lipták, p. 46).

There are different air pollutants released to the atmosphere. This causes a discomfort to the living things, and it negatively impacts on their health. The substances released to the atmosphere in their natural state are called primary pollutants. These are gases like carbon dioxide, sulfur dioxide, dust, fumes from various reactions, or bad odors. These substances undergo certain reactions when they mix with other compounds in the atmosphere to form the secondary compounds (Owen, p. 43).

Causes of air pollution

Air pollution is caused by various pollutants that are released to the atmosphere. These pollutants may be released either naturally or by human beings. There are different kinds of pollutants, some of which are visible, whereas others cannot be seen by the naked human eye. Nonetheless, any foreign substance that is introduced to the atmosphere is referred to as a pollutant. There are various causes of air pollution. Carbon dioxide released from green houses contributes to global warming. This is one of the numerous air pollutants. This causes discomfort to the living things due to changes in the environmental conditions engineered by the global warming aspect. Carbon dioxide is also released by automobiles and power plants. This results from the combustion of fuel and burning of fossils like the natural gas and gasoline compounds. This increases carbon dioxide levels thus contaminating the air that living things breathe. Chlorofluorocarbons also form a greenhouse gas. This gas is a major contributor to global warming that is being experienced in the world today. This gas also depletes the ozone layer.

Sulfur dioxide, a major component of smog usually released from industries and factories, is another major pollutant. It is a very dangerous gas as it pollutes the air, and can also cause water pollution because it mixes with rain to form acid rain. Acidic rain causes corrosion to buildings, and it is harmful to both human and plant health. Apart from industries, volcanic eruptions also release massive amounts of sulfur dioxide that is harmful to human health. Another major cause of pollution is methane that is released from decomposition of organic matter in swampy areas. This gas has a great impact on human health because of the bad odor. Nitrogen oxides, forest fires, and natural radio activity are other causes of air pollution.

Lead compounds, which come from reactions of lead or lead combustion, is another air pollutant. Lead pollution can also come from waste incineration and house renovations. Lead pollutants are detrimental to human health as such pollutants can lead to the damage of the nervous system. Hydro carbons, when burned normally, produce gases that dissolve in the atmosphere hence polluting the environment. These gases are detrimental to human health as they combine with atmospheric gases to form complex compounds that can affect the respiratory system. Ozone (O3) is also another cause of air pollution. This compound is formed by complex reactions of chemicals and other forms of hydro carbons. When these compounds are formed, they affect the natural environment like the plants, animals, as well as buildings (Harrison, p.169).

Effects of air pollution on human health and the environment

Effect on human health.

Air pollution can have a great effect on human health, which can both be long term and short term depending on the source of the air pollutant. The severity of the effect that air pollutants have on human health depends on various aspects. It can depend on the concentration and the mixture of the pollutant; the duration of the pollutant exposure to the atmosphere; and the source of pollutant. Some pollutants may not cause serious effects on human health, while others can be very serious to a point of causing death. Air pollution can have adverse effects to the body system. Nevertheless, the severity of pollutants in the body depends on the part of the body system that has been affected. There are various effects on human health, which have been discussed below.

Human respiratory system: Air pollutants can have serious impacts on the human respiratory system. This is because the health safety of the entire respiratory system depends on the quality of the gas that is inhaled in to the lungs. Human beings inhale Oxygen gas from the atmosphere to facilitate the respiration process in the body. However, if the atmosphere is polluted, this gas is inhaled together with the pollutants into the respiratory system. The inhaled substances are likely to cause malfunctioning that may lead to health complications. This is because the respiratory system is sensitive to any pollutant that could be in the air. Air pollutants like ozone, carbon monoxide, and other free metals released to the atmosphere may damage lung tissue cells, alveoli, and air sacs. These are the tissues where gaseous exchange occurs, and if they are affected, this may cause malfunctioning of the lungs. This can easily lead to death if not well addressed. Research has indicated that human beings can only stay for five minutes without fresh air; any time longer than this can lead to death (Gurjar, p.109).

Heart and lung diseases: Air pollutants, if not addressed, can be a major cause of heart diseases common in human beings. For example, if carbon monoxide is inhaled into the respiratory system, it mixes with hemoglobin in the blood system hence forming an unstable and complex compound called carboxyhaemoglobin. This unstable compound stops the normal respiration because it blocks the blood vessels and lessens the amount of oxygen that enters the blood system. This can cause diseases like hypertension. Pneumonia and bronchitis are also diseases arising from pollution of the atmosphere. In addition, exposure to air pollutants may lead to respiratory diseases like lung cancer and other complicated heart diseases (Friis, p. 258). The other effects on human health that may arise due to air pollution include eye irritation due to smoke and other gaseous substances released to the atmosphere; nose and throat irritation; severe headaches; and allergic reactions.

Effects to the environment

Apart from adverse effects on human health, air pollution negatively impacts on the environment in various ways. Acid rain, from reaction of oxides of Sulphur and Nitrogen with rain, has an adverse effect to the environment. When these oxides combine with rain water in the atmosphere, they form compounds of their acids that are harmful to the environment. Acid rain falls to the earth as precipitation mixing with soils to form acidic soils. Acidic soils cannot support plants and/or crops. This poses a great danger to the environment hence leading to adverse effects like soil erosion due to lack of vegetation. Dry precipitation is in the form of gaseous compounds sinking into the soils, whereas wet precipitation comes in the form of rain or water. This acid rain falls on trees damaging them hence leading to destruction of forests. When the rain water from acidic rain is carried to water bodies, it makes them unsuitable for aquatic life.

Depletion of the ozone layer: Ozone layer is a gas found in the upper part of the earth’s atmosphere. The ozone layer reflects harmful sunlight rays hence protecting human health from adverse heating effects. Air pollutants released to the atmosphere deplete the ozone layer, making it non functional. Some of the compounds causing ozone depletion include chlorofluorocarbons. Depleted ozone causes direct sunlight to hit the earth’s surface hence destroys the plants and trees.

Climate changes: This is caused by accumulation of gases in the atmosphere hence increased global warming. These gases include excess carbon dioxide and methane gas. This causes rise in temperature, which has a significant impact on plant and animal life.

Eutrophication: This refers to high concentrations of nutrients like nitrogen in water bodies that stimulate algae formation hence causing great danger and threat to aquatic life. This process naturally occurs in water bodies during the aging process. However, the addition of air pollutants accelerates this process when nutrients are increased. Examples of these pollutants include oxides of nitrogen, which increases the amount of nitrogen that enters the aquatic ecosystems (Steyn and Rao, p. 521).

Air pollution effects to wildlife: Wildlife is affected by air pollutants. Any toxic compound formed due to air pollution has direct impacts on wildlife in several ways. The wildlife experience health difficulties if they are exposed to these pollutants for a long time.

Crop and forest damage: Air pollution harms crops in several ways. The ozone, which appears on the lower part of the atmosphere as ground ozone, causes reduced growth by reducing survival chances to plants and forest trees. In addition, when acid rain is released from the atmosphere, it damages plants and crops. Also, when acidic rains fall directly to the soil, it leads to the formation of acidic soil that cannot support plant growth.
