Air Pollution Essay: Greenhouse Gases and Climate Change
1489 Words6 Pages
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that…show more content…
Aerosols absorb and reflect sunlight, which increases the atmospheric temperature, enhancing greenhouse warming. There are two main classifications of air pollutants; primary, those emitted directly into the atmosphere, and secondary pollutants, those that form in the air when primary pollutants interact and react. Air pollution is most commonly caused by anthropogenic emission, the most predominant being the burning of fossil fuels. Other major causes of air pollution include chemical processing, agriculture, airborne particles and Volatile Organic Compounds (VOC’s) (Irina Ignatova 2008). Air pollution does occur naturally as well, from volcanic eruptions, water vapour, animal resuscitation and lightening fires. Air composition changes regularly, depending on the place, season and weather, as well as for many other reasons (NSW Gvt. 2008). The most prevalent air pollutants, as established by the Australian Government, are; carbon monoxide, lead, nitrogen dioxide, ozone, particles and sulfur dioxide (2. Aust. Gvt. 2009.). Carbon monoxide occurs in the atmosphere naturally at low levels, and is mainly sourced from volcanoes and bushfires. It is emitted from anthropogenic sources by exhaust emissions and some industrial activities (2. Aust. Gvt. 2009). Since approximately 1950, anthropogenic sources of CO2 have escalated, as Figure 1 below demonstrates.

Air Pollution Essay 1 (100 words)
Air pollution is a most serious problem of the current time all over the world especially in the large cities because of the huge level of industrialization. The release of such air pollutants in heavy concentrations such as smog, particulates, solid materials, etc are getting settled over the city, causing air pollution and health hazards to the people. Lots of dirty wastes produced by people on daily basis especially in the big cities polluting the whole atmospheric air to a great extent.
The release of gaseous pollutants from burning fuel of motor vehicles, industrial processes, burning of garbage, etc are contributing to the air pollution. Some natural pollutants like pollen, dust, soil particles, natural gases, etc are also the source of air pollution.
Air Pollution Essay 2 (150 words)
Air pollution is the mixing of any harmful substances to the atmosphere fresh air causing huge level of damages, human health disorders, reducing the quality of life, etc. Air pollution is increasing day by day because of the increasing number of industries. Such polluted air never remains at one place however spread to whole environment and affecting the lives of the people all through the world. Death rates of the human beings have been increased because of increased variety of diseases. The polluted air we breathe every moment causing lungs disorders and even lung cancer thus affecting the health of other body organs.
Air pollution is continuously damaging the whole ecological system and affecting the lives of plants and animals as well. It has reached to the critical stage and affecting the whole atmosphere by allowing more harmful radiations from the sun to the earth. Again polluted air acts as a better insulator which prevents heat to get escaped back into the space.

Air pollution is one of the main environmental issues nowadays. There are many reasons behind regularly increasing this air pollution. Most of the air pollution is caused by the automobiles, transport means, industrialization, growing cities, etc. The release of several harmful gases or dangerous elements from such sources is causing the whole atmospheric air pollution. Ozone layer is also getting affected too much by the air pollution which causes serious disturbances to the environment. Increasing need of the ever growing human population is main cause of pollution. Daily human being activities causing dangerous chemicals to release, making atmosphere dirtier than ever and forcing the climate change negatively.
Industrialization process releases many harmful gases, particles, paint and batteries contains lead, cigarettes releases carbon monoxide, transport means releases CO2 and other toxic substances to the atmosphere. All the pollutants are being in contact with the atmosphere, destroying the ozone layer and calling harmful rays of sun to the earth. In order to reduce the level of air pollution we should bring some huge changes to our habits on daily basis. We should not cut trees, use public transportation, avoid spray cans, and so many activities in the favor to reduce the effects of air pollution.
Air Pollution Essay 4 (250 words)
Air pollution is the mixing of foreign substances to the whole atmospheric air. Harmful and toxic gases emitted by the industries and motor vehicles causing huge damage to the living organisms whether plants, animals or human beings. Some of the natural and various human resources are causing air pollution. However, most of the air pollution sources are stem out of the human activities like burning fossil fuels, coal and oil, release of harmful gases and substances from factories and motor vehicles. Such harmful chemical compounds like carbon dioxide, nitrogen oxides, carbon monoxide, sulphur dioxide, solid particles, etc are getting mixed to the fresh air. The level of air pollution has become increased by great extent because of 690% increase in damaging pollutants because of the expanded need of motor vehicles from last century.
Other source of the air pollution is decomposition of garbage in landfills and disposal of solid wastes which are emitting methane gas (dangerous to the health). Rapid growth of population, industrialization, increased use of automobiles, aeroplanes, etc has made this issue a serious environmental problem. The air we breathe every moment is full of pollutants going to our lungs and whole body through blood causing uncountable health problems. Polluted air is causing damage to the plants, animals and human beings in many direct and indirect ways. If the environmental protection policies are not followed seriously and strictly, the increasing level of air pollution may increase up to one million tons annually in the recent decades.

When the fresh air gets polluted by means of dust, toxic gases, smoke, motor vehicles, mills and factories, etc called air pollution. As we all know that fresh air is the most important element of the healthy life, we need to think that what happens if whole atmospheric air gets dirty. First of all air pollution is the matter of great regret for the whole human fraternity. Some of the big reasons of the air pollution are use of poisonous fertilizers, insecticides, pesticides in the agricultural sectors by the innocent farmers in order to increase the crop production. Released chemicals and hazardous gases (ammonia) from such fertilizers are getting mixed into the fresh air and causing air pollution.
Burning of fossil fuels such as coal, petroleum including other factory combustibles are the major causes of air pollution. Variety of smoke emissions from the automobiles such as cars, buses, motorcycles, trucks, jeeps, trains, aeroplanes, etc are also causing air pollution. Increasing number of industries is causing release of toxic industrial smokes and harmful gases (like carbon monoxide, organic compounds, hydrocarbons, chemicals, etc) from the factories and mills to the environment. Some indoor activities of the people like innocent use of cleaning products, washing powders, paints etc emits various toxic chemicals to the air.
The ever increasing level of air pollution also enhances its negative and harmful effects to the health of living beings. Air pollution is causing global warming to increase because of increasing atmospheric temperature due to the increasing level of green house gases. Such green house gases again causing green house effect and forcing sea levels to increase, glaciers to melt, weather to change, climate to change, etc. Increasing air pollution is causing many lethal diseases (cancer, heart attack, asthma, bronchitis, kidney diseases, etc) and death to occur. Various important animals and plants species have been destroyed completely from this planet. Increasing level of harmful gases in the environment are causing the occurrence of acid rain and depleting the ozone layer.

Increasing concentration of the harmful and toxic materials in the fresh air of the atmosphere is causing air pollution. Variety of foreign particles, toxic gases and other pollutants released from various human activities are affecting the fresh air which has adverse effect to the living beings like human beings, animals and plants. The level of air pollution depends on the type and amount of pollutants released from various sources. Topographical and meteorological conditions are increasing the spread and concentration of the pollutants. Variety of raw materials used in the manufacturing process in industries is increasing the type and quantum of emissions of harmful gases. Increasing population density is demanding the need of more industrialization which ultimately causes air pollution.
Air Pollutants like harmful liquid droplets, solids particulates, and toxic gases (oxides of carbon, halogenated and non-halogenated hydrocarbons, nitrogen and sulphur gases, suspended inorganic particulate matters, inorganic and organic acids, bacteria, viruses, insecticides etc) which are generally not the constituents of fresh air are very hazardous to the plant and animal life. There are two types of air pollution sources which are natural sources and man-made sources. Some natural sources of the air pollution are like volcanic eruptions, volcanoes (ashes, carbon dioxide, smokes, dust and other gases), deflation of sands, dusts, salts spray from seas and ocean, soil particles, storms, forest fires, cosmic particles, rays, bombardment of asteroid materials, comets, pollen grains, fungal spores, viruses, bacteria, etc.
Man-made sources of the air pollution are industries, agriculture, power plants, automobiles, domestic sources, etc. Some of the air pollutants from the man-made sources are like smokes, dust, fumes, particulate matters, gases from kitchen, domestic heating, emissions from different vehicles, use of insecticides, pesticides, herbicides, heat created from power plants, smokes, fly ash, etc. Because of the increasing number of air pollutants, it has been divided into two types such as primary pollutants and secondary pollutants. Primary pollutants are those affecting the fresh air directly and emitted from smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, sulphur dioxide, hydrogen sulphide, ammonia, nitric oxide and radioactive compounds. Secondary pollutants are those affecting the air indirectly by chemical interactions to the primary pollutants and other atmospheric constituents such as sulphur-trioxide, ozone, hydrocarbons, nitrogen dioxide, etc.
The get together effort of the human beings all over the world may help in controlling the level of air pollution. The establishment of industrial estates should be away from residential areas, motivate use of tall chimneys (with filters and electrostatic precipitators) instead of small, promote use of high temperature incinerators, use of non-combustive sources of energy, promote use of non-lead antiknock agents in the gasoline, promote re-plantation and so many positive efforts.
Air pollution essay given above are useful to a range of students studying in classes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. You can select any of them according to your need and requirement either to use in exam or essay writing competition at any event.
