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

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.

With the rise of the industries and the migration of people from villages to towns in search of employment, there has been a regular increase in the problem of proper housing, and unhygienic conditions of living has led to rise in factors which increase pollution.

The mad rat race among countries of the world to compete against each other in the index of development has harmed the health of the people itself. Progress in agriculture and industry is taken as an indicator of development. This resulted in the exploitation of natural resources in a reckless manner. Thus, pollution has been an inevitable gift of industrialisation and urbanisation.

The growth of industries has given rise to the problem of proper disposal of waste material of the industries. Many a times, the waste products of these industries contain poisonous elements which if disposed without being properly treated, pollute the rivers and other water bodies. Thus, we face the problem of water pollution.

The poisonous water and waste product of the factories mingles with the water bodies and poisons them. Resultantly, the aquatic life gets affected. Fish die, disturbing the ecological balance. The water too is rendered useless which can neither be used for drinking or washing. This also results in the reduction of the area of water bodies. Such a situation arises when non-degradable products are dumped on fallow land or on the banks of rivers and sea shores.

Waste materials such as plastics, polythene, bottles etc cause land pollution and render soil infertile. Moreover, dumping of dead bodies of men and animals, washing of clothes and utensils too add to the problem. In recent surveys, Sabarmati river in Gujarat, Yamuna and Ganga rivers have been found to be excessively polluted. Yamuna has been described as an ‘Open Drain’.

Another major problem of pollution is the air that we breathe in being polluted by the smoke pouring out of chimneys and automobiles. No doubt, air pollution takes place even by volcanoes, cyclones, forest fires etc. But human activities are more responsible for causing air pollution. Gases like CO 2 , CO, SO 2 , are emitted which mix with air and cause great harm to the human body, flora and fauna.

The use of dry farm waste, dry grass, leaves and coal used as domestic fuels in our villages also produce harmful gases. Acid rain occurs due to excess of SO 2 in the air. The most tragic incident of air pollution is the Bhopal Gas Tragedy when the dangerous Methyl Isocyanide was emitted from Union Carbide Fertiliser Factory in 1984 which killed thousands of men, women and children, and rendered thousands of others handicapped.

Fire crackers, nuclear explosions, air conditioners, refrigerators, organic solvents, pesticides etc also contribute significantly in polluting air. Air pollution not only causes various kinds of allergies, respiratory problems and other health problems but also affects the vegetation, animal life and the environment. The soot which contains high concentration of hydrocarbons proves very harmful for monuments like the Taj Mahal.

Another very subtle form of pollution is noise pollution. Technology has given us comfort along with a cacophony of harsh and unharmonious sounds. This problem is extremely severe in big towns and cities. The maddening horns, loud speakers, music systems etc cause metabolic, hearing and other kinds of disorders. Noise pollution may also lead to a nervous breakdown or madness. Uttar Pradesh Pollution Control Board (UPPCB) recently revealed that even silence zones, such as hospitals, schools and residential areas are suffering from high decibels of sound.

Thus, we see that there are various kinds of pollutions which need to be checked in time. Problems like ozone depletion, global warming, greenhouse effect, change in climatic and weather conditions, melting of glaciers etc have arisen due to pollution. Strict and serious measures should be taken to control it. Industrial waste should be properly treated in special treatment plants before letting it flow into the water bodies or dumping it. The pollution department of Farrukhabad issued directives to close all textile dyeing units, polluting the Ganga river.

Use of organic manures should be encouraged instead of chemical fertilisers to prevent soil pollution. Planting of trees should be encouraged and cutting down of green trees should be strictly checked. Unleaded petrol should be used in vehicles. The directions of the Supreme Court to manufacture cars as per Euro I and Euro II norms should be strictly enforced.

Short Essay on Pollution 200 Words in English

Below we have given a short essay on Pollution is for Classes 1, 2, 3, 4, 5 and 6. This short essay on the topic is suitable for students of class 6 and below.

Industries should have proper emission systems and should conform to the laws in order to ensure safety of the people living in residential areas around. Strict laws should be legislated and enforced regarding the keeping of our sea shores and river banks clean. For example, Himachal Pradesh was the first state to ban plastic and polythene bags, to save the fragile ecology of Himalayas. But the law exists only on paper.

The horns of automobiles should be checked as per the limits prescribed by law. Loud speakers music system etc should be strictly prohibited after ten at night and vehicles should not be allowed to play their stereos at high volume.

The Government, after launching online green clearance systems for industrial and infrastructure projects, now will monitor treatment of industrial effluents and emissions, in a similar manner, by using online systems. The purpose is to bring transparency and facilitate real-time analysis of waste discharge.

The Government should also try to educate people about various kinds of pollution and create public awareness. People should be involved in helping to reduce and control pollution. Moreover, punishments should be strictly given in case of violation of any environmental law so that such people learn a lesson. Until we all get serious and resolve to make our planet a better place to live in, humanity stands amidst grave danger of perishing and being destroyed due to the severe and increasing problem of pollution. Franklin D Roosevelt, former American President, said the same about pollution:

“A nation that destroys its soils, destroys itself.”

In simple terms, pollution is defined as the contamination of the physical and biological constituents in the earth’s atmosphere. It affects human life and the natural environment to a very great extent. It degrades our natural resources, from the water we drink to the air we breathe. While writing an essay on Pollution, you must mention the major four types of pollution which are as follows:

• Air Pollution : Air pollution is the contamination of air in the atmosphere when harmful or excessive quantities of substances such as smoke and harmful gases from industries, CFCs and oxides produced by automobiles, the burning of solid wastes, etc. are introduced into the environment.
• Water Pollution : This refers to the contamination of natural resources of water, due to the addition of harmful chemical, biological or physical materials, which includes industrial wastes, oil spills, domestic and farm wastes, pesticides, as well as mining and agricultural wastes, to water resource which make it unusable.
• Soil Pollution : Land/Soil Pollution occurs due to the degradation of the earth’s surface by different commercial, industrial, agricultural and domestic activities. Causes of soil pollution also include mining, deforestation, dumping of e-waste and other industrial wastes, usage of harmful chemicals such as insecticides, pesticides, etc.
• Noise Pollution : Excess noise due to sounds created by machines, loudspeakers, microphones, loud music, noise from industries, construction and civil engineering works etc. lead to noise pollution.

You can include various causes and health effects in your essay on Pollution from the following table:-

Pollution is the addition of unwanted substances which are incorporated into the environment that can damage our Earth. There are mainly four types of pollution, these include water pollution, air pollution, soil pollution, and noise pollution. One should note that any form of pollution is the result of careless activity carried out by man. We, humans daily dump waste directly into water bodies which leads to water pollution.

Vehicle emissions of smoke into the atmosphere impede the ability of all living things to breathe, leading to air pollution. Our garbage is dumped into landfills directly, which results in soil pollution. Although it cannot be seen, noise pollution is a severe type of pollution that can harm our ears.

The biggest threat planet Earth is facing is pollution. Unwanted substances leave a negative impact once released into an environment. There are four types of pollution air, water, land, and noise. Pollution affects the quality of life more than any human can imagine.

Due to air pollution, even teenage kids have developed various respiratory diseases. Water pollution has led to diseases in children. The waste we humans dump on the land or chemical fertilisers which are put on the land for agricultural purposes causes land/ soil pollution.

If the soil quality deteriorates due to such practices, the soil will become infertile and no crops could be grown in future. The government has launched various schemes over the years to fight pollution but individual efforts can also play a vital role.

Start by replacing plastic bags for shopping with cloth bags, stopping littering on roads and stopping wasting water are some of the basic things to start with that can lead to big changes in the environment.

One of the most critical threats faced by our planet in the present-day scenario. Environmental pollution is a global issue affecting people around the world. It is occurring in different forms, whether by affecting the air we breathe or the water resources we utilise for several purposes.

Air pollution came into being with an increase in the level of carbon dioxide, with the increase in pollutants which are contaminating the air and causing breathing discomfort as well as skin diseases to human beings. Talking about the other aspect, there is no life without water.

The water bodies are polluting and becoming unsafe for drinking or any other use because of industrial development, rapid urbanisation and various other reasons. Due to air pollution, diseases that can occur in human beings are asthma, various skin diseases, cancer, etc. Therefore, it is the essential need of the hour to take serious steps to reduce pollution to its core.

At a personal level, we can minimise environmental pollution by taking public transport or carpools to reduce vehicular smoke, avoiding firecrackers at festivals and celebrations can also cut down on air and noise pollution, and not using fertilisers and pesticides which can cause both water and soil pollution, and switching over to organic farming. The government can also bring strict rules and regulations to lessen industrial pollution.  

To sum up, any type of pollution is harmful to the environment with serious consequences like global warming, uneven climatic changes, etc. Due to our greediness and illegal human activities, the innocent lives of animals are lost. The time has come to join hands and work towards preserving and protecting the environment for the present as well as future generations.

Recently there has been a drive to convert the buses and the three-wheelers running in Delhi from diesel-driven to CNG. Why was this large scale change found necessary? The reason was that with the rise in the population, the number of buses and three-wheelers also increased. The diesel-driven buses and three-wheelers emit smoke which goes into the atmosphere and the air. This smoke contains very unhealthy gases.

People breathe this air. The result is that their lungs inhale these polluted gases within which causes so many lung diseases even leading to bronchitis, asthma, and tuberculosis. The rise in these diseases led the government to think and this led to this policy of converting these vehicles into CNG. Ever since this has been done the proportion of air pollution has largely decreased.

Then there is water pollution. The water we drink is lifted from the rivers, stored and then sent to us through pipelines. What is happening to these rivers? Those rivers which used to be called our ‘holy’ rivers Ganga and Yamuna receive all the sewage from the city drains and so large a quantity of this sewage is that the river is not able to carry it away. The river water gets all polluted with all the filth that falls into it and it is this water that is pumped to the city’s water tanks. Even the underground water is becoming polluted as the filth and garbage over the earth seeps down when it rains and the underground water also gets polluted.

All the lakes, ponds, and even the wells of today contain polluted water. The large scale industries which are growing in large numbers to meet the demands of the growing population send out effluents that fall in the rivers, lakes, and ponds and make their water unworthy of drinking.

People are cutting down trees. This is because, more population, more need for fuel and timber. Trees emit oxygen by day which purifies the atmosphere loss of trees means loss of oxygen the healthy gas.

Even too much use of fertilizers and pesticides in our farming process is also a cause of atmospheric pollution. As we go around a town we find big heaps of garbage with all the rotting material. All this has been heaped by us we are responsible for it. But this rotting sends up gases which mix in the air and pollute the atmosphere. We get rid of the garbage from our homes but make the whole neighborhood polluted. The civic sense is lacking the civic authorities also are not able to make proper arrangements of garbage disposal.

Below we have given a short essay on Pollution is for Classes 1, 2, 3, 4, 5, and 6. This short essay on the topic is suitable for students of class 6 and below.

Even the plastic bags, so much in use these days, are a cause of pollution as these are thrown away and do not get destroyed, but are recycled. The recycled plastic bags are very dangerous for health any eatable kept in them turns unhealthy.

The growth of slums in big towns are a great source of pollution. People live in the most unhealthy surroundings, commit all sorts of nuisances and all this causes atmospheric pollution.

• The problem of pollution is growing every day and is causing a risk to the population of the country.

What is necessary is that not only the administration but people, in general, must understand the gravity of this problem and each one should do his best to keep the atmosphere clean. Plant more trees; dispose of the garbage in the proper way. Keep the rivers clean, do not allow unhealthy ways of life to grow it is each and every man’s job to save the country from pollution.

Effect of Pollution Essay

Environmental Pollution influences the quality of nature’s life more than one can assume. It acts in unnatural ways, sometimes which cannot be viewed by the open eye. Though, it is very much existing in the atmosphere. For example, you might not be capable to see the natural gases (oxygen, Carbon-dioxide) present in the air, although they are still existing. Furthermore, the pollutants which are slaughtering the air and raising the levels of carbon dioxide are very critical for humans. Raised levels of carbon dioxide will lead to global warming. Get Speech on Pollution from Here.

Moreover, the water is contaminated in the name of industrial growth, religious exercises and more will create a deficiency of drinking water. Human life is not possible without water. Furthermore, the process by which waste is discharged on the land ultimately ends up in the soil and becomes toxic. If land pollution continues happening at this pace, we will not have productive soil to plant our crops on. Consequently, serious steps must be taken to decrease pollution to the core.

Essay on Environmental Pollution in 500 Words – Reduce of Pollution

After discovering the harmful effects of pollution, one should perform the task of stopping or decreasing pollution as soon as possible. To overcome air pollution, people should start taking public transport such as buses, auto-rickshaws, pool-cabs to reduce pollution generated by vehicles. Try to avoid bursting crackers especially at the time of festivals which causes a huge amount of toxic pollution in the air. Avoiding crackers will also help to reduce noise pollution. Foremost is we must foster the habit of recycling. All the used plastic materials are been dumped in the oceans and land, which causes pollution. Therefore, we should not dispose of such toxic materials off after use, instead, reuse them as long as you can.

We must also inspire everyone to plant more trees that will absorb the harmful gases and make the air disinfectant. While talking on a higher level, the government must restrict the usage of fertilizers to control the soil’s fertility. Also, industries must be forbidden from discharging their waste into oceans and rivers, causing water pollution. Collectively, all types of pollution are dangerous and come with grave outcomes.

Everyone must step towards development ranging from individuals to the industries. As dealing with this problem calls for a collective effort, so we must unite and work for it. Furthermore, the lives of innocent animals are being lost because of such human actions. So, all of us must come and together and take a stand to become a voice for the unheard and making this earth pollution-free.

• I will not use vehicles for short distances.

Question 3. Clear, transparent water is always fit for drinking. Comment. Answer: No, this is not true that clean, transparent water is always fit for drinking. It is possible that they may carry disease-causing microorganisms. Thus, it is good to purify water before drinking.

Question 4. You are a member of the municipal body of your town. Make a list of measures that would help your town to ensure the supply of clean water to all its residents. Answer: These are the measures that would help our town to ensure the supply of clean water to all its residents:

• Chlorine tablets should be made available.
• Proper cleaning of the water tank from time to time.
• The water supply pipes should not come in contact with the sewage pipes.

Question 5. Explain the differences between pure air and polluted air. Answer: Pure air contains 78% nitrogen, 21% oxygen and 0.03% C02. Other gases such as argon, methane, neon, water vapour, etc. are also found in small quantities. When this air is contaminated by unwanted substances which have harmful effect on both living and non-living things like nitrogen oxide, sulphur oxide, carbon monoxide, etc., is said to be polluted.

Question 6. Explain circumstances leading to acid rain. How does acid rain affect us? Answer: Nitrogen dioxide, sulphur dioxides are the pollutants which react with the water vapour present in atmosphere to form sulphuric acid and nitric acid. These acids come down with the rain, making the rain acidic. This is called acid rain. Following are the affects of acid rain:

• It increases corrosion of metals.
• It damages buildings and sculptural materials.
• It removes the basic nutrients such as calcium from the soil.
• It causes direct damage to plants and crops.
• It causes skin eruptions in human being.

Question 7. Which of the following is not a greenhouse gas? (a) Carbon dioxide (b) Sulphur dioxide (c) Methane (d) Nitrogen Answer: (d) Nitrogen

Question 8. Describe the ‘Greenhouse Effect’ in your own words. Answer: Basically, the greenhouse effect means warming of the earth’s environment. When the sun’s ray falls on earth, a part of the radiation that falls on the earth is absorbed by it and a part is reflected back into space. Greenhouse gases present in the atmosphere trap these radiations and do not allow heat to leave. This helps in keeping our planet warm and thus helps in survival. CO2, methane and CO are the gases responsible for this effect.

Question 9. Prepare a brief speech on global warming. You have to deliver the speech in your class. Answer: Good Morning, Respected teacher and my dear friends, As we all know the continuous increase in the temperature of earth is called global warming. Global warming is basically caused by pollution of air, excessive heat which is trapped by the greenhouse gases. Global warming is a threat to life as it causes a lot of health problems. We may have to face dire consequences due to global warming. That’s all friends. Thank you for the attention. Have a good day.

Question 10. Describe the threat to the beauty of the Taj Mahal. Answer: Taj Mahal has become a matter of concern due to pollutants in air that are discolouring its white marble. Acid rains due to increasing air pollution has started corroding the marble. Suspended particulate matter, such as the soot particles emitted by Mathura oil refinery, has contributed towards the yellowing of the marble. Thus making Taj Mahal losing its beauty.

Question 11. Why does the increased level of nutrients in the water affect the survival of aquatic organisms? Answer: Increased level of nutrients in the water affect the survival of aquatic organisms as these act as nutrients for algae to flourish and once these algae die, they serve as food for decomposers like bacteria and a huge amount of oxygen in water body gets used up. This results in decrease in the oxygen level, which may kill aquatic organisms.

NCERT Solutions for Class 8 Science Chapter 18 – 3 Mark Questions and Answers

Question 1. Mention three causes for erosion of soil. [KVS2007] Answer: Soil erosion is caused by water and wind due to three major factors :

• Deforestation — due to increasing population and increasing industrialisation.
• Overgrazing — by large animal populations has destroyed vegetation and result in barren land.
• Poor Farming Method — ploughing, loosens the soil and destroys its natural resources.

Question 2. What is acid rain ? Why is it harmful to us ? [NCT 2011] Or Explain circumstances leading to acid rain. How does acid rain affect us ? Answer: The industries release pollutants like sulphur dioxide and nitrogen dioxide. These gases react with the water vapour present in the atmosphere to form sulphuric acid and nitric acid. These come down with the rain, making the rain acidic. Acid rain is harmful to us because it destroys buildings and damages crops and trees. Examples:

• affects the monuments like Taj Mahal.
• spoils the growth of plants.
• causes irritation of eyes in human beings.

Question 3. Why is greenhouse effect called so ? How does it cause global warming ? [NCT 2010] Answer: It is called so because earth’s atmosphere acts like a green house made of glass in which sunlight enters through transparent glass but the heat released by plants in the form of infrared radiations is not allowed to escape. Carbon dioxide does not allow heat to escape causing global warming.

Question 4. Describe the ‘Green House Effect’ in your own words. [NCERT] Answer: The heat rays of the sun (infra-red) can pass through the carbon dioxide present in the atmosphere.

Similarly there could be several other examples of pollution. As for now, we will discuss below the types of pollution.

Types of Pollution

The five major types of pollution are given below –

1) Air Pollution

Its main source is the burning of fossil fuels by the transportation vehicles and smoke emanated from the factories.

2) Water Pollution

Its main source is the runoff water from urban settlements, agricultural fields and release of byproducts from factories.

What is Pollution

When any external unwanted substance, generated by a human activity enters into the environment, it causes pollution. Causes of pollution are always human induced and the natural cause of pollution is almost negligible.

There are a number of human activities those cause pollution. Tons of toxic waste generated as a byproduct in factories is left into the rivers and streams, polluting them; thousands of cubic meters of harmful gases are released by transportation vehicles, polluting the air; improperly disposed waste from urban settlements, got strewn on land and water, resulting in land as well as water pollution.

Now that we have got an idea on what is pollution, we will move on to discussing some of the significant effects of pollution.

Effects of Pollution on Environment

Pollution has a widespread effect on the environment as discussed below-

1) Polluted Air

Pollution contaminates the natural air, making it harmful to breathe. For example toxic gases released by transportation vehicles mix with the air, resulting in its pollution. When this air is inhaled by a human or animal, it causes severe respiratory ailments. Some species of animals and plants, which are highly sensitive to such kind of pollution, die.

2) Polluted Water Bodies

Improper disposal of waste generated by areas of human settlements cause this waste to reach our naturally occurring water bodies in form of runoff. The urban waste consists of several toxic compounds including plastic. This waste is non biodegradable and stays in water, making it hazardous to consume. It also results in the depletion of aquatic species population which are highly sensitive to pollution.

3) Soil Toxicity

Pollution cause due to agricultural activities like the use of chemical fertilizers, result in toxicity of the soils. Chemical fertilizers are made up of harmful chemical compounds, which got mixed with the soil, ultimately making it toxic. It affects the species of flora as well as fauna those depend on the purity of the soil for their survival.

Everything that constitutes the part of the environment, that is the water bodies, air, flora and fauna, are in some way or the other get affected by the pollution. Moreover, pollution also causes global effects like Greenhouse gas effects, Global Warming and Acid Rain. Global warming refers to an increase in earth’s average surface temperature and results in conditions like famine, flood and drought. Below we will discuss about the effects of pollution on major Indian cities like Delhi, Noida, Ghaziabad, Lucknow and Varanasi.

It must be known that an AQI between 0 to 50 is considered “Good”; 51 to 100 is considered as “Satisfactory”; 101 to 200 is considered as “Moderate”; 201 to 300 is considered as “Poor”; 301 to 400 is considered as “Very Poor”; 401 to 500 is considered as severe and a value above 500 is considered “Severe-plus or Emergency”.

Pollution Level in Delhi

As per a survey done by the World Health Organization , the National Capital Territory of Delhi stands at the lowest position in terms of air quality index, among 1650 other major cities around the world. In Delhi, children are the worst affected and as per a study, nearly 2.2 million or 50% of all children are suffering irreversible damages due to poor air quality.

Air Quality Index (AQI) of Delhi remains usually moderate (101-200) during January to September months. However, the AQI rapidly deteriorates during the onset of winter months from October to December. Often during these months the AQI reaches to a hazardous level of 500 plus.

The Particulate Matter levels of PM2.5 and PM10 Particulate Matters in Delhi reach up the level of 999 micrograms/m 3 . This is much above the safe limit, which is 60mg/m 3 for PM2.5 particles and 100mg/m 3 for PM10 particles.

Burning of the roots of paddy crop during the winter months in the adjoining states of Punjab and Haryana makes the situation worst in Delhi, by causing dense smoke. This method is traditionally called “Parali” and is one of the prime constituents of Pollution in Delhi.

Pollution Level in Noida

Noida, also known as New Okhla Industrial Development Authority, located in the western Uttar Pradesh, bordering Delhi is immediately behind the national capital in terms of poor air quality. Incessant construction works in and around Noida, in addition to the heavy vehicular pollution and cold winter air causes a dense, thick smog. The term smog is used for a mixture of smoke and fog, suspended in the atmosphere. The Air Quality Index of Noida also gets very poor up to the level of 500 during the winter months of October to December.

The particulate matter level of this western UP district is by and large at par with that of Delhi, often the two competing with each other for the highest concentration of particulate matters.

Pollution Level in Ghaziabad

Ghaziabad often tops the list of north Indian cities with worst Air Quality Index and pollution. Here also, like Delhi and Noida the AQI goes past the hazardous level of plus 400, mostly during the months of October to December.

The main reason behind such a poor Air Quality Index of Ghaziabad is industrial pollution and waste burning. The city is flanked by the industries on the outskirts, which results in a dense smoke emanating from the factories as well as from the transport vehicles plying to the industrial area.

The PM10 level of Ghaziabad reaches up to four times of permissible levels during October to December. Sometimes, this value is reached during the Deepawali festival, due to the incessant bursting of crackers and smoke emanated from them. PM10 Particulate Matter, which has a permissible limit of 100 microgram/m 3 , often is recorded nearing around 500 micrograms/m 3 in Ghaziabad.

The Air Quality Index (AQI) of the capital of Uttar Pradesh, Lucknow, fluctuates between moderate and poor, often crossing the 250 plus mark. Though, the situation is definitely not as bad as Delhi NCR, nevertheless, it still is alarming and requires concrete action.

The worst Air Quality Index of Lucknow was recorded as 265 in the first half of the November month. The quantity of suspended Particulate Matter has also increased significantly in Lucknow’s residential areas since the last decades.

The air of Lucknow is found to be consisting of very fine Particulate Matters, PM2.5 with concentration just below 870 microgram/m 3 , which is very highly hazardous indeed.

Pollution Level in Varanasi

The ancient pilgrimage city of Varanasi has always been in news for its everyday fluctuating population of tourists. Being the Parliamentary Constituency of Indian Prime Minister, Mr. Narendra Modi since 2014, it has become the centre of development, with everyday construction works of some kind or the other. Though the construction is good for the city’s development point of view, it is also causing some of the worst recorded downfalls in its Air Quality.

AQI of Varanasi in 2019 is ranked at the third position on the World Health Organization’s list of fifteen most polluted cities in the world. The people of Varanasi are facing respiratory ailments and other complications due to the ever continuing construction work.

Recorded Air Quality Index (AQI) of Varanasi reaches up to 300 which falls in the “Poor” category. The Level of Particulate Matter found in Varanasi is PM2.5, the value of which fluctuates within the range of 53microgram/m 3 to 100microgram/m 3 , which is extremely unhealthy for sensitive groups and children.
