Speech on Pollution : Any unwanted substance present in the environment that contaminates our natural resources causes pollution. Such substances are known as pollutants. Today, pollution has become an existential problem for every living being on earth. Every country, every region, and every community is facing the challenges posed by pollution. Human activities have been degrading natural resources for ages. 

From burning fossil fuels to cutting trees, almost every selfish human activity is responsible for causing pollution in the environment. The cars we drive, the plastic we use, the clothes we wear, the garbage we throw, etc. all cause pollution. To combat pollution and reduce its impact on the environment, various governmental and international organizations have been formed. The United Nations Environment Programme (UNEP) is one such organization, which deals with pollution, its causes, and consequences at the global level.

1-Minute Speech on Pollution

‘Hello and welcome to all my mates and teachers. Today, I stand before you to present my speech on pollution. There is a lot about pollution in our Geography books. From the causes of pollution to its preventive measures. But have we ever followed any of these preventive measures? 

There are different types of pollution, such as air, soil, water, radioactivity, noise, etc. All these pollutions have different sources, which not only disturb the natural environment but also have adverse effects on human health, biodiversity, ecosystems, and the climate. 

Pollution is a fight that requires a collective effort from developed and developing countries. Recently, there was a debate where the first world countries were requesting others to equally take responsibility for environmental pollution. However, this is not the case, because the major damage to the environment is caused by developmental activities in these first-world countries. 

The damage is already down, and now is not the try to cry over spilled milk. We are in this together, and we have to take responsibility for our actions. With well-structured, alternative strategies and cooperation, we can combat pollution.

Thank you.’

2- Minute Speech on Pollution

‘Hello and welcome to everyone present here. As a conscious human being, I am happy to present my speech on pollution. Pollution is known as the introduction of unwanted substances into the environment, which disrupts the natural environment and overall health of the planet. One of the major concerns of the pollution is climate change. 

The history of pollution is older than one century. In 1896, a Swedish scientist named Svante Arrhenius first predicted the changes in atmospheric carbon dioxide levels, which may substantially increase the surface temperature and because a major cause of global warming. 

The first international summit to consider pollution as a global concern was the 1972 Stockholm Convention. The United Nations Environment Programme (UNEP) was the outcome of this international climate convention. UNEP deals with all environmental problems at the global level and organizes various environmental programs to raise awareness about pollution, climate change, global warming, etc.

Today, our terrestrial and marine ecosystems are facing existential threats due to pollution. Deforestation, industrial waste, and chemical pollutants are wreaking havoc on biodiversity. The loss of habitats, the decline of species, and the imbalance in our ecosystems paint a grim picture of the toll pollution takes on our natural world.

There are different types of pollution, such as air, water, noise, soil, radioactivity, thermal, plastic, etc. Burning of fossil fuels, industrial processes, vehicle emissions, and agricultural activities causes air pollution. Water pollution is caused by industrial discharges, agricultural runoff, untreated sewage, oil spills, and dumping of chemicals in rivers, ponds and lakes. Improper disposal of industrial waste, agricultural practices, use of pesticides and fertilizers, and contamination from hazardous substances cause soil pollution. The list goes on as new types of pollution are being discovered by scientists. 

Pollution not only affects our environment but also disrupts our daily life as it affects our health, and biodiversity and is a major cause of climate change. Every country and its citizens must recognize the importance of addressing pollution through regulations, sustainable alternative practices, and environmental conservation efforts.

Speech on Pollution for Students in English | 3 Minutes Speech

December 10, 2020 by Sandeep

Speech on Pollution : The presence of harmful contaminants into the environment causing damage to the air, water and land resources in our environment is called pollution. Pollutants could be naturally occurring like volcanic ash or human-made materials like smoke, chemicals and trash substances. Pollution is a global problem. Common types of pollution are – air, water, soil, noise and light pollution. Long term exposure to pollution can lead to chronic diseases, cancers and other fatal disorders.

Speech on Pollution 500 Words in English

Below we have provided Pollution Speech in English, written in easy and simple words for class 7, 8, 9 and 10 school students.

“Pollution is a necessary result of the inability of man to reform and transform waste.” Said by Patti Smith

A warm welcome to one & all present here. Today we are here to discuss the very burning topic of the decade that is pollution. According to a report by the World Health Organization, eleven out of twelve cities with the highest levels of particulate pollution are located in India. A study says 86% of the Indian water bodies are deemed critically polluted. Land pollution has resulted in a loss of around 25 billion tons of valuable soil each year.

As per the Global Burden of Disease Report by the World Health Organization, the prevalence of hearing loss was estimated to be 6.3% in India due to noise pollution. These are the few reports which have become often in today’s media & still we are not serious about the problem. Air Pollution in India has become a severe problem. As per a study, at least 140 million people in India breathe air that is ten times over the safe limit.

57% of the total air pollution are by the industries, 27% by vehicles, 17% by crop burning & around 5% by Diwali fireworks. India, as a country, is the third-largest greenhouse gas producer after China and the United States. There is a decrease in the Air Quality Index of all the major cities of the country. All these have resulted in an increase in several airborne diseases & the premature deaths in India.

Now the second type of pollution which has impacted is water pollution. The largest source of water pollution is untreated sewage. Other factors include agricultural runoff & unregulated small scale industries, solid wastes etc. These factors have resulted in contamination of both surface water & groundwater. Lack of toilets & defecation is also adding to the cause. Many rivers water has been declared unfit for domestic use due to high pollution with organic matter.

Not only humans but also the life in water is getting adversely affected by this.Now let us briefly discuss the land degradation. Soil Contamination or land pollution is caused by xenobiotic chemicals or other alteration in the natural soil. It is due to the intensive farming, deforestation, improper disposal of wastes & industrial activities. Except for these few major pollution’s, there are several other types of pollution’s like noise pollution, light pollution, plastic pollution which has been ignored since long.

Pollution cannot be seen or felt, but its effects are evident on the earth & the biodiversity. Global warming, increase in sea level, extinction of species, scarcity of drinking water, decrease in air quality, acid rain etc. are few major impacts which are posing a threat to the existence of human life on earth. To sum it up, all types of pollution’s are detrimental to the planet & comes with terrible consequences.

All of us must take steps to bring the changes in industries to the individual level. A joint effort by the government & the citizens will curb the situation from getting worse. So let us make a stand for our mother earth & listen to its pains to save it from the upcoming global calamity.

Thank You. Have a good day.

Short Speech on Pollution 150 Words in English

Below we have provided a short speech on Pollution, suitable for class 3, 4, 5 and 6 students.

Very good morning to everyone present over here. Today the topic we will be discussing is a very well known & often heard in the news. Pollution is the introduction of contaminants into the environment, which affects it adversely. Pollution can be of several types like air pollution, water pollution, soil pollution, noise pollution, etc. Not to our surprise, human activities are the major cause of misbalanced environment & pollution.

The rise in population, industrialization, deforestation, and mining are the major contributor to the damage we have done to the environment. We have entirely exploited the natural resources & the nature around us. According to an estimation by the World Health Organization, air pollution causes premature death of around 8.8 million people worldwide which is likely to increase in coming years.

Water pollution has raised the alarming issue of the sharp decrease in domestic water for use. Land pollution has resulted in a loss of around 25 billion tons of valuable soil each year. Noise pollution has affected both behaviour & health of humans. Not only the humans but pollution has given a significant threat to the flora & fauna on the earth too.

Pollution has also led to many more serious problems like global warming , melting of polar ice, ozone layer depletion, and climatic disturbances on a global level. The reasons are many & all of us need to acknowledge that we have created a threat to life on earth. The consequences of pollution are hazardous. We must become more alert & proactive towards the situation & make every effort to turn the situation another way around.

All of us must pledge to bring a better tomorrow for the World. With an urge for everyone to give their best in the joint effort to eliminate pollution, I would like to end my speech.

Speech On Environmental Pollution - 10 Lines, Short and Long Speech

Environmental pollution speech -.

Environmental pollution is a significant problem in the world. The majority of this pollution is a result of human activity. Some of the leading causes of environmental pollution include human activities such as burning fossil fuels, using vehicles, dumping industrial waste, cutting down trees and forests, and using a lot of plastic.

10 Line Speech On Environmental Pollution

The addition of any impure substance in the form of solid, liquid, or gas to the environment is called pollution.

Pollution can make the whole environment dirty by polluting the air, water, and land.

The chemical particles also pollute the environment.

Honking and loud volume sound create noise pollution which is very harmful to the ears.

When artificial fertilisers mixed with the soil, land pollution occurs.

Throwing garbage in an open area pollutes the surroundings and results in spreading several diseases.

Various Animals also suffer from pollution.

The extraction of impure particles from factories pollutes the water.

Improper sewage management causes pollution, we should cover the drainage pipes properly to protect the environment.

Metals like Arsenic Mercury pollute the groundwater

Short Speech On Environmental Pollution

Environmental pollution poses a significant threat to the atmosphere, as well as to the health and livelihood of humans, plants, and animals. Any living thing can only continue to exist in this world with a clean-air environment. It would not be easy to imagine life on Earth if the climate wasn't pure and clean.

Pollution is present in a variety of forms and originates from lots of sources. Some forms of environmental pollution include noise pollution, soil pollution, water pollution, and air pollution. Any type of environmental contamination is harmful and has unwanted effects.

Impacts Of Environmental Pollution

Ocean acidification

Ozone layer depletion

Global warming

Species extinction

Environmental pollution has risen as a result of global industrialization and modernization. Making new rules and upholding them strictly will help stop the harm that environmental pollution faces to the entire world. Utilising environmentally friendly fuels and properly collecting and dumping garbage are two approaches to reducing environmental pollution.

An improved solution might be to restrict deforestation and encourage tree planting. We must take action to minimise postorder to safeguard the health and future of the next generation. Both directly and indirectly, environmental pollution impacts how people and other species live. These living things have long coexisted with humans on earth.

Long Speech On Environmental Pollution

The environment is our home, where we live, or the earth's surroundings are known as the environment. But the pollution human beings spread is known as Environmental pollution. Currently, our environment is polluted more than an exception.

Environmental pollution prevents the earth from restoring its typical ecosystem. Life on earth has been both created and destroyed by human forces. Human activity is a significant factor in the environment's destruction.

Our respiratory system is damaged daily because we take carbon and dust particles through our noses because of environmental pollution. These are brought on by a large number of industrial and manufacturing facilities through the burning of fossil fuels and carbon dioxide from vehicle combustion.

Any pollutant, including human and chemical factory waste, can easily contaminate water. We also utilise this water for drinking and cultivating crops. However, they also become polluted as a result of infection. Additionally, an animal eventually dies after consuming this same poisoned water.

Because of the containment of polluted soil and water, the crop or agricultural produce also gets toxic. Additionally, contaminated food affects our organs and overall health. These crops are laced with chemical substances from the beginning of their lives until harvest time.

Environmental pollution is also a result of climate change. Additionally, it impacts the ecosystem's biological and physical elements. Climate changes such as ozone depletion, greenhouse gases, and global warming are causes of environmental pollution. Moreover, they may have dangerous effects on future generations. The unpredictable extremes of cold and heat impact the earth's natural system.

Types of environmental pollution-

Noise Pollution - Noise pollution also called sound pollution happens when the level of noise in the environment gets too high. Noise pollution is caused by things like car horns, loudspeakers, music systems, and industrial activities. Noise pollution is harmful for our ears.

Soil Pollution - Soil pollution, also called land pollution, takes place when solid waste, non-biodegradable materials, chemicals, and other things are dumped on open land. Waste from cities and runoff from farms are the main things that pollute the soil. Due to soil pollution, we did not get good quality food.

Water Pollution - Waste from industries and sewage water is not treated well enough before being dumped into rivers and other water bodies, which results in water pollution. It is harmful to humans as well as aquatic life.

Air Pollution - Air pollution happens when particles and other harmful gases are released into the air and make it unhealthy. The air we breathe is polluted by the smoke that comes out of factory chimneys and automobiles. Air pollution affects our respiratory system.

Furthermore, several unstable climate changes, such as earthquakes, famine, smog, carbon particles, shallow rain or snow, thunderstorms, volcanic eruptions, and avalanches, are brought on by environmental pollution.

Most importantly, we must take action if we want to live on Earth. These steps will help safeguard our future and the future of the next generation. We have only one environment, sh; we take care of it. We should give proper knowledge to the new generation about the environment. Additionally, we should plant at least one tree in a month.

Pollution Speech | Speech on Pollution for Students and Children in English

Pollution Speech:  Pollution continues to be one of the most significant problems of this century. It has become a chronic problem of every nation to face various kinds of pollution ranging from soil, land, air, water to even radioactive pollution. Humanity is well aware of what pollution is and how it has adverse effects on humans and all living organisms. Pollution is such a thing that poisons the mother earth with its ill-effects causes imbalance in the ecosystem, which leads to hazardous natural disasters and many harmful diseases.

Many such harmful effects include soil erosion, tsunamis, landslides, floods, drought, and diseases such as cancer.

However, with changing times, pollution is now associated with natural resources and pollution of human-made resources. Thus, now there are new kinds of pollution, such as visual pollution. Visual pollution refers to the impacts of pollution on the aesthetics of a human. Visual pollution causes disturbance in humans’ humans’ peace, such as the electric wires running across the roads, wastes left unattended, open drains, sewage canals, etc.

Long and Short Speeches on Pollution for Students and Kids in English

Below mentioned are the short and long speeches covering the topic “Pollution.” The word limit is approximately 500 words. The students and kids can refer to this speech and accordingly restructure the essay based on their requirements.

Long Speech on Pollution 500 words in English

Long Speech on Pollution is usually given to classes 7, 8, 9, and 10.

Good morning/evening to everyone present here.

Let us take a moment to think about how we, as a generation, have contributed to the growth of pollution. There is no one in particular whom we can blame or call out to increase the level of pollution. The entire humankind is responsible for the continuous rise in pollution. The harmful effluents and substances released in the atmosphere by the factories, industries, and plants contaminate the environment, which is very harmful to humans to live in such an atmosphere.

These wastes generated are directly drained out to the larger water bodies (rivers, ponds, seas, and oceans), which get mixed in due course with the drinking water causing water pollution. The toxins that get mixed with the water like various bacteria, germs, etc. can be life-threatening to the living beings consuming this water daily.

Land pollution is one of the most dangerous kinds of pollution, leading to a huge number of diseases like malaria, dengue, etc. air pollution is another vital matter that we should be concerned about. Air pollution refers to the toxic materials present in the air that has risen to the extent that it can become a threat to all living beings. The harmful toxins in the air deplete the ozone layer and enable harmful Ultra Violet radiation from the sun to directly enter Earth, causing serious health problems.

These toxins also are the major reason for acid rain, which damages the age-old monuments of the world. Next comes water pollution, which has posed a serious threat to the aquatic life on Earth, endangering various aquatic species’ species’ lives. The industrial waste sewage, oil spills, and wastewater also contribute to the cause of water pollution. The amount of drinking water is reducing with each passing day, putting the lives of many in distress.

Radioactive pollution is another dangerous kind of pollution that has severer effects on the living population. It consists of the harmful alpha beta and gamma rays along with free neutrons. Some of the major harmful effects include skin cancer, burning of the skin, improper organ build-up of the offsprings, etc.

Knowingly or unknowing humanity has themselves given rise to many harmful elements to receive the benefits by exploiting nature. One example in this regard can be that of the use of fertilizers. We created fertilizers to increase the production of food crops; however, this has become one of the major reasons for land and water pollution due to the chemicals present in those fertilizers. Numerous such examples can be given in this regard. However, I will not be going into the details of it.

Thus, as a community, it is our sole responsibility to fight against pollution by minimizing the uses of non-biodegradable substances and use more eco-friendly things. We can overcome pollution by taking up simple measures in our day to day lives; thus, taking small measures is of utmost importance from the very start. Even simple things like using jute bags instead of plastic can go a long way.

It is important for us to take individual actions and for governments and policy makers to implement regulations and promote clean energy sources to reduce air pollution. We must all work together to preserve the health of our environment and ourselves. Thank you.

2nd Speech on Air Pollution (20 min)

Good morning/afternoon/evening everyone,

Today, I would like to talk about one of the most pressing environmental issues that we face today – air pollution.

Air pollution is the presence of harmful substances in the air that we breathe. These harmful substances can include particulate matter, nitrogen oxides, sulfur dioxide, carbon monoxide, ozone, and many other pollutants . These pollutants are released into the air by a variety of sources, including industrial and transportation activities, as well as natural sources like wildfires and volcanic eruptions.

The effects of air pollution on our health and the environment are well-documented. Air pollution can cause a range of health problems, including respiratory illnesses like asthma, lung cancer, and heart disease. It can also harm the environment by causing acid rain, damaging crops, and contributing to climate change.

In many parts of the world, air pollution has become a major public health crisis. According to the World Health Organization, outdoor air pollution is responsible for around 4.2 million premature deaths each year. This makes air pollution one of the leading causes of death worldwide.

So, what can we do to address this problem? There are several steps that we can take at both the individual and societal levels.

At the individual level, we can take steps to reduce our own contribution to air pollution. This can include reducing our use of single-use plastics, using public transportation or carpooling instead of driving alone, and reducing our energy consumption by turning off lights and electronics when they are not in use.

At the societal level, governments and businesses can take steps to reduce air pollution on a larger scale. This can include implementing regulations to limit the amount of pollution that industries are allowed to emit, investing in cleaner forms of energy like wind and solar power, and improving public transportation infrastructure.

Ultimately, addressing air pollution will require a coordinated effort from individuals, governments, and businesses around the world. By working together, we can help to reduce the harmful effects of air pollution on our health and the environment.

3rd Speech on Air Pollution (15 min)

Ladies and gentlemen,

I stand before you today to talk about a problem that is affecting all of us, whether we realize it or not. The problem I’m referring to is air pollution. This is an issue that has been around for a long time, and it continues to get worse with each passing day. It’s time for us to take action and do something about it.

Air pollution is the presence of harmful substances in the air we breathe. These substances can come from a variety of sources, including factories, cars, and even natural events like wildfires. When we breathe in polluted air, it can have serious consequences for our health. It can cause respiratory problems, heart disease, and even cancer.

Unfortunately, air pollution is a problem that affects everyone, regardless of where they live. It’s a global issue that requires global solutions. We all have a responsibility to do our part to reduce air pollution.

One of the main sources of air pollution is transportation. Cars and trucks release pollutants into the air, including carbon monoxide, nitrogen oxides, and particulate matter. These pollutants can have a serious impact on our health, especially for those who live in cities with high levels of traffic.

To address this issue, we need to promote alternative forms of transportation. We can encourage people to use public transportation, ride bikes, or walk instead of driving their cars. We can also promote the use of electric or hybrid vehicles, which produce fewer emissions than traditional gasoline-powered cars.

Another major source of air pollution is industry. Factories and power plants release large amounts of pollutants into the air, including sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants can have a serious impact on the health of people who live near these facilities.

To address this issue, we need to promote cleaner forms of energy. We can encourage the use of renewable energy sources like wind and solar power, which produce fewer emissions than fossil fuels. We can also promote energy efficiency, which can help reduce the amount of energy we need to produce.

Finally, we need to take action at the individual level to reduce air pollution. There are many simple things we can do to make a difference. We can carpool or use public transportation instead of driving alone. We can turn off lights and electronics when we’re not using them. We can reduce our use of single-use plastics, which can take hundreds of years to decompose.

In the end, air pollution is a serious problem that affects all of us. We need to take action to reduce the amount of pollutants we release into the air. This requires a global effort, but it also requires action at the individual level. We all have a responsibility to do our part to protect the air we breathe and the health of our planet. Thank you.

4th Speech on Air Pollution (10 min)

I am here today to talk to you about a very important issue that is affecting our planet: air pollution. Air pollution is the presence of harmful substances in the air that we breathe.

Smokes and toxic dust from the industries and factories get mixed to the air and causes air pollution. Such polluted air is very bad for the lungs when we breathed air in. Sewage and other wastes from the industries and factories have their ways directly to the large water bodies (river, lakes, seas, etc) and they get mixed properly to the drinking water causes water pollution. Such polluted water (containing germs, bacteria, toxic substances, viruses, etc.) is very bad to the health of human beings, animals and plants (whoever drinks this water).

Now-a-days, environment is not peaceful because of the increasing noise level through the transport, sound systems, electronic devices, etc. Such voices are causing noise pollution and very bad to the natural stamina of our ears. Excess and unbearable noise of vehicles, loud speakers, etc., can cause ear problems and even permanent deafness especially in older people and kids.

Man-made chemicals from the industries and factories such as hydrocarbons, solvents, heavy metals, etc., get mixed into the soil when people use herbicides, pesticides, fertilizers, etc., or through the spill or underground leakage of the chemicals. Such contaminants in the form of solid, liquid or gas are causing soil or land pollution which is contaminating the whole earth. Such contaminants are also causing water and air pollution as they get mixed to the underneath water supplies and some chemicals produce harmful vapors respectively.

Ever increasing the use of plastic by the people is causing huge level environmental pollution and adversely affecting the wildlife, wildlife habitat, and humans. Thermal pollution is increasing because of the huge level usage of water as a coolant by the power plants and industrial manufacturers. It is causing the change in temperature of water in the large water bodies. It is very harmful to the aquatic animals and plants as raised temperature of water decreases the oxygen level of water.

My dear friends, we have been surrounded by the thick cover of the pollution from all around means upside, downside, and both sides. We are living in pollution but the most surprising thing is that some people even do not aware of it. Big and developed countries are highly responsible to this increased level of pollution all around the world. This is the very challenging issue of this planet which needs to be solved on urgent basis. It cannot be solved by the effort one or two countries, however; it can only be solved if all the countries do hard and strict effort from various aspects regarding this issue.

Each and every person of the country should be aware and watchful of this problem, its causes, and harmful effects to the living beings. Use of harmful and toxic chemicals by the people, industries and factories should be banned very strictly by the government. Common people should be made aware by the educational institutions and government agencies through camps or other means to use environment friendly things and habits to save the environment and keep it healthy.

Thank You All.

Speech on Pollution 2

Good morning to the Sir, Madam, and my dear colleagues. My name is … I study in class … I would like to speech today on the topic of pollution in India. As we have gathered here to celebrate this event, I have selected this special topic to open in front of you in the favor of humanity. My dear friends, as we all are well aware of the word pollution. I want to tell you that pollution is a slow and sweet poison which is disturbing us and our living very badly in all the aspects such as physically, mentally, socially, and intellectually. It is not so easy to stop it at once however, not so tough to prevent it gradually.

Pollution has become a major worry for our planet and people. It happens when harmful substances get into our surroundings. To put it simply, pollution messes up the natural balance of our environment. What’s more, it really affects how we live, and it plays a big part in making the Earth get hotter.”

The main causes of the pollution are wastes from the chemical industries and factories pouring their wastes directly into the large water bodies. Such contaminants gets introduced into the natural environment and causing adverse change. Pollution can be man-made or natural however pollution from the natural sources is less harming than the man-made. Pollutants or components of the pollution get intermingled into the natural resources such as water, air, soil, etc. Pollution was started from the prehistoric times however currently it has been boom because of the deforestation, urbanization, technological advancement, and advanced life style.

People should understand the importance of environment they live in and respect the one given by God to live a simple life on the earth (the only known planet having life). Various types of pollution such as water pollution, soil or land pollution, air pollution, and sound or noise pollution, all are very harmful to the health of human beings and animals. People have been used to of technological advancement in their lives and forgot about all the existing problems because of that. Use of various fertilizers and other chemicals in the agriculture for many years in order to get better and healthy crops has created serious problem to the humanity.

Increasing number of vehicles in the cities is another main cause of air pollution. Diesel vehicles are more dangerous than the petrol vehicles as they emit more carbon dioxide and carbon monoxide, both are very harmful to the health and atmosphere. My dear friends, it is very necessary for the common public to be aware of the bad effects of pollution and run in the direction against pollution to reduce its effects. We should plant more green plants in the surrounding areas and sides of the roads in order to maintain the natural equilibrium in the environment.

Pollution is affecting our lives so we have to take individual steps and do every possible things what we can do. We should not depend only on our government actions for some positive changes. Common people like us are the main factor to stop the spread of pollution.

Speech on Pollution 3

Good morning to the respected sir, madam and my friends. At this event, I would like to speech on pollution, the most serious issue of the modern time. The most powerful demon in the form of environmental pollution has disordered the ecological balance of the atmosphere. It is a big global issue however varies in its nature and extent with regional variations. It is the topic of anxiety and debate to solve this issue. It is not the time to accuse one another however it is the time to fight this demon together with some effective weapons. Rich, powerful and developed countries are highly responsible for such a huge spread of pollution and global warming however all countries are bearing this problem.

We have been the victim of this environmental pollution however we cannot deny that this problem is created by us. It is we who have given rise to this problem due to increased irregular consumption level of natural resources and living patterns of the modern time. Pollution is the result of fast urbanization, deforestation, industrialization, technologies and unmanageable wastes from industries and factories. It is getting boom because of the high consumption level of fertilizers in agriculture, emissions from chimneys, smoke from motor vehicles, etc.

Increased number of vehicles has increased the consumption level of fuels which is causing the air pollution to a great extent. Over population is another big issue of this ever increasing pollution. It has created the need of more houses, cutting of plants to make living places, and other modern needs of the people is leading to the pollution. No one is thinking about this issue but everyone is busy in money making and collecting things of physical comfort. Because of overpopulation the consumption of fresh water, consumption of wood, etc., has increased. Increasing human needs of physical comfort (such as AC, TV, electricity, electronic devices, fertilizers, freeze, washing machine, etc.) is directly related to the spread of pollution.

Now, we lack the fresh air to breathe, fresh water to drink, fresh land to get healthy crops, and peaceful environment to sleep. We are bearing all that because of our negligence and carelessness. We have to work hard continuously to get natural fresh environment to get real physical and mental comfort. We have to get control over this demon and save life here by planting more trees, well managing wastes from industries and factories, reducing need of heavy vehicles, and other effective steps.

Speech on Pollution 4

Good morning to all. At this event celebration, I am going to recite a speech on pollution. My dear friends, pollution is not an unknown word for us. We are well aware of it, its causes and bad effects on the environment and our lives. A natural environmental contains everything required for the survival, growth, and development of the living beings on earth. However, what happened if this environment gets polluted by various means. Everything will get disturb and interfere with the survival of life here.

Various dangerous and harmful substances from different places in the environment are leading to various kinds of pollution, such as water, soil, air, land, noise, and heat pollution, among others. When smoke and harmful particles are released from factories and plants, they mix with the air and create air pollution.

Pollution has happened because of the mixing of dangerous unnatural ingredients into the natural resources which causes imbalance in the ecosystem and thus various health hazards to the human beings and animals. Pollution is damaging the ecosystem and destroying the balance. This is all because of the industrialization, urbanization, deforestation, technological advancement, over population, etc. All these are the big reason of increasing level of toxic gases (causing air pollution), solids/liquids wastes (causing water, food and soil pollution) and sound (causing noise pollution). All are the reason of imbalance in the natural ecosystem in some direct or indirect ways.

Pollution is really bad for the environment and living things. It can make people and animals sick and can even kill them. When harmful chemicals get into our water, they hurt the animals that live in it and make the water not safe to use. Bad gases in the air can give people lung problems like asthma.

It has been the matter of great concern and consideration and need to solve. Because of the pollution, babies are born with variety of birth defects and life expectancy of people has been low because of the lethal diseases like cancer, diabetes, heart problem, etc. I want to share you some facts about pollution: According to the WHO, around 6.7% percent of all deaths and 7 million premature deaths worldwide are due to the air pollution. Mississippi River carries around 1.5 million metric tons of nitrogen pollution. Pollution caused by China may change United States weather patterns. Approximately, 56% trash of United States has covered landfills (half of that is only paper).

The most damaging pollutant causing global environmental pollution is fossil fuel. It has created various evil effects especially through air, water and soil. Protecting our environment and improving its natural value is the fundamental duty of all of us. We should try our best to tackle this problem and give a nice healthy future to our next generation.

• I will use public transport as far as possible.
• I will generate awareness among people to reduce air pollution.
• I will plant more and more trees because trees help to keep the environment clean and reduce air 1 pollution.
• 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.

• 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. After reflection from the earth they are not allowed to leave the atmosphere. The trapped heat rays in the carbon dioxide from a warm blanket around the earth. This effect is known as greenhouse effect.

Question 5. Why does the increased level of nutrients in the water affect the survival of aquatic organisms?

Speech on Air Pollution

Air pollution can be defined as the contamination of air by the release of pollutants like harmful gases, dust, biological molecules, etc. Do you want to know more about the topic? Read the following article and try to draft an enriching speech on air pollution – one of the interesting speech topics for kids .

Table of Contents

Air pollution speech in english, speech on pollution in delhi, two-minute speech on air pollution, frequently asked questions on air pollution, sample speeches on air pollution.

A couple of sample speeches on air pollution are given below. Go through them and utilise the resource to better understand the topic.

Air pollution is one of the major challenges faced by humanity in recent times. In simpler terms, it can be defined as the mixing of external harmful gases and particles in the atmosphere. Such dangerous gases mix with the air we breathe, which ultimately passes into our bodies through inhalation and causes respiratory disorders and death.

Have you ever heard the term ‘pollutants’? Pollutants are the substances that cause pollution. There are mainly two types of air pollutants – one is the primary pollutant, and the other one is the secondary pollutant. Primary pollutants are the substances that directly cause air pollution. For example, Sulphur dioxide discharged from industries. It requires no other substance to react and produce pollution. The secondary pollutants are the substances formed by the combination and reaction of the primary pollutants. We are all familiar with the substance – ‘smog’, right? Smog, formed by the mixing up of smoke and fog, is a perfect example of a secondary pollutant. To eradicate air pollution from our planet, we have to control the production of pollutants. For our better future, let’s join hands – to limit the release of greenhouse gases into the atmosphere, avoid unwanted plastic usage, stop using personal vehicles to travel shorter distances, use clean energy resources like wind, solar, and geothermal energies, manage industrial wastes effectively, minimise the use of fire products, try to follow the three R’s – Reduce, Reuse, and Recycle, and conserve and plant more trees. Other than all these, there are numerous measures that can be taken to reduce air pollution. The foremost thing is to be a responsible human being. Realise that protecting our home is never a duty but our responsibility.

‘Air Pollution in Delhi’ has been a grave concern for a long time now. But still, there has been no solution to this problem. Delhi is considered one of the most polluted cities in the world. According to the World Health Organisation (WHO), Delhi has been ranked as the world’s worst pollution hotspot. The magnitude of pollutants present in the ‘Capital of India’ is massive. Contaminated air present in the atmosphere is causing devastating impacts on the health of the individuals and the environment. It is shocking to perceive the truth that the quality of air in Delhi is six times more polluted than the quality of air that is safe for human beings.

Do you know which are the 30 worst polluted cities in the world? It is really shocking to find that nearly 20 cities on the list are in India. Population explosion is one of the major reasons responsible for air pollution. As per the records, the number of people living in cities has increased dramatically over these years. There is a rise of about 25 per cent in the total population, making it hard for the nation to control pollution. Some of the main sources of air pollution in Delhi include the exhaustion of gases by vehicles, open waste mismanagement and burning, discharge of wastes from industries, combustion of fuels for cooking, etc. Apart from all these above-mentioned sources, the smoke and contaminants discharged during a public festival is also a major contributor to air pollution.

COVID19 pandemic has taught us many lessons in our lives. One such lesson is that it made us realise that the intensity of pollution can be controlled if people are ready to act responsibly for preserving nature. So let us plan and act together for a better future.

Air pollution causes an imbalance of gases in the atmosphere, and global warming is one of the aftereffects of such loss of balance. As we all know, our atmosphere is well balanced with different gases in it. A slight variation in the arrangement of these gases is enough for the disintegration of the balance of our ecosystem. Greenhouse gases act as pollutants and result in the contamination of the air. It traps the heat produced by the sun inside our planet and ultimately results in the global temperature rise.

Other than global warming, the catastrophic effects of air pollution include acid rain, depletion of the ozone layer, loss of ecosystem, respiratory diseases, increase in infant mortality rate, extinction of wild species, drought and so on. So the responsibility to maintain the balance of a certain percentage of gases in the atmosphere is ours. For our survival, it has to be controlled.

“Polluting the air is even more foolish when it is done through a fire that is fuelled by the trunk or branches of a tree.” These are the words said by Mokokoma Mokhonoana, an author from South Africa. It’s high time to stop our irresponsible behaviour towards our mother nature. So let’s join hands for a fresh and safe future.

Essay on Pollution

Introduction.

Pollution has become a very common yet serious issue in today’s world. It has been there in different forms since a long time even before human evolution such as volcanic eruptions, wildfire which lead to various photochemical reactions in the atmosphere. The current concern is that it is rising day by day due to various resources of pollutants. And, one of the main pollutants are humans and man-made machines. It is right to say that pollution is damaging the mother earth severely and we, humans, should play our part to prevent it from happening.

What is Pollution?

Pollution sepsis is the presence of contaminants in the natural environment that causes harm and damage and therefore leads to adverse changes.

Kinds of Pollution

There are mainly three kinds of pollution - 1) Air Pollution, 2) Water Pollution, and 3) Soil Pollution. 

Air Pollution

Air Pollution occurs due to the presence of harmful gases and substances in the air. It is due to vehicle emission, dust and dirt, poisonous gasses from the factories etc. To reduce air pollution, we should use carpooling or public transport rather than using our private mode of transportation whose harmful gas emission only adds to the problem, we should also actively avoid burning trash or other materials etc.

Water Pollution

Water Pollution happens when toxic substances get mixed in various water bodies such as lakes, oceans, rivers etc. Here toxic substances refer to the Chemical fertilizer, Industrial waste, Sewage and wastewater, Mining activities, Marine dumping etc.

Soil Pollution

Soil pollution depicts the contamination of soil due to the presence of toxic substances due to Excessive use of fertilisers and pesticides, deforestation, industrial waste etc . To maintain the soil’s fertility, the government must limit the usage of fertilizers and plant more trees.

There are a few other pollutants causing pollution apart from the aforementioned ones, such as Radioactive pollution. This is one of the rarer types of pollution. It occurs due to the presence of radioactive substances such as the presence of nuclear waste in air, solids, liquids or any other place.

Effects of Pollution on Human Health

Pollution is increasingly having a major effect on the health of human lives. People are gettin g affected by different types of deadly diseases due to the various pollution in air, water and soil. Here are the different diseases humans face due to different pollution.

Due to Air Pollution

Air is an essential part of human life. Humans cannot live without breathing air. But, air pollution causes major damage to human lives. Here are some of the major diseases caused due to air pollution.

Lung cancer

Major coronary heart disease

Respiratory problems

Due to Water Pollution

Water is another source of life. Any living being cannot survive without drinking water. But the continuous degradation and pollution of major water bodies are also causing deadly diseases to humans and animals. It is also affecting marine life. Since water is consumed all the time, it’s pollution is causing a lot of deadly diseases. Some of the major diseases caused by water pollution are as follows:

Hepatitis A

Diarrhoea 

Due to Soil Pollution

Soil is an important part of our lives. The land on which we are walking or travelling is made with soil. Due to all the chemicals mixed with the soil and degradation due to the same, it is inevitable that many harmful chemicals come in contact with our body and cause many skin diseases or in forms of food crops that are planted on such polluted soil. Direct contact can cause a lot of problems for us humans. Some of the major diseases caused due to soil pollution are as follows:

Different types of cancer

Damage of the nervous system due to contact with lead present in the soil.

liver and kidney failure

What are the Different Methods to Reduce Pollution?

The degrading quality of all the important elements like air, water and soil is affecting the lives of many children, adults as well as animals. We need to keep our environment safe and use effective methods to reduce pollution. 

Methods to reduce Air Pollution

Some of the effective methods to reduce air pollution are as follows:

Regulation of air through chimneys: The industries should disintegrate the harmful gas from the air prior to its release from the chimneys. They should check and avoid using harmful gases, which are the major causes of air pollution.

Use of public transport or cycle: If you are travelling to distant places, it is recommended to take public transport. Or if you are going to any shops or buying any garment, it is always better to use your cycle. Public transport can take you to different places along with other people; this will help reduce air pollution. If you can cycle, it will reduce air pollution and another added benefit is that it will keep your health in check.

Reduction of fires and smokes: In the dry season, many people burn plastic, papers, dry leaves, which creates a big fire and smoke that creates a harmful layer of fog suspended in the atmosphere. It is better if you stop burning plastic to reduce smoke.

Methods to Reduce Water Pollution

Some of the effective methods to reduce water pollution are as follows:

Avoid disposing of plastic and waste materials: To keep the water free from any pollution, the first thing is to avoid disposing of any sort of plastics or food waste water material in water. The waste materials get dissolved in the water and harm the aquatic life along with those who drink the water. 

Reduce use of chemicals: you should avoid purchasing harmful chemical products that can get mixed with the water and pollute it. The biggest examples are pesticides and insecticides, which causes a major effect on marine life.

Reduce use of detergents: Detergents have many strong chemicals which can cause the leather to water and wash your clothes. If these detergents get mixed with water, they can pollute the soil.

Methods to Reduce Soil Pollution 

Some of the methods to reduce soil pollution are as follows:

Avoid disposing of harmful chemicals: The industries should avoid disposing of harmful chemicals in the soil. It can change the structure and components of the soil making it an unusable surface of land for vegetation. 

Eat food in biodegradable containers: As you dispose of the food containers in dustbins, it is good to use biodegradable food containers despite using plastic containers, which are harmful to the soil.

Plant more trees: The structure of the soil can be improved by planting more trees. Trees help to hold the soil together and improve the soil quality. Hence we should plant more trees.

How to Reduce Pollution Gradually?

Upon learning about the harmful effects of pollution, it is everyone’s responsibility to take some steps towards prevention. We should be aware of all the possible preventive measures to help reduce every kind of pollution such as to curb air pollution, we should avoid bursting crackers during any festival or using public transport or carpool to reduce air pollution or cutting down the usage of loud loudspeaker, and public honking would help in noise pollution. We should always be aware of this situation and take measures accordingly. It’s us who should be cautious in the beginning and make everyone else surrounding us conscious as well.

Short speech on world environment day.

World Environment Day is celebrated every year on June 5 globally. It is a day on which we spread awareness about the environment and the need to conserve it. Moreover, it is essential to advocate for a greener environment and conservation of nature. It is quite simple as when we conserve the environment today, the future generations will be able to lead a healthier life. We cannot be so selfish and use up all the resources for ourselves. World Environment Day is the perfect opportunity to make people aware of the issues we are facing and how one can contribute to saving it. Thus, it is quite important in its own way.

Importance of World Environment Day

World Environment Day reminds us to strengthen the world and ensure that nature is preserved at all costs. It throws light on the causes which are causing serious harm to our environment. For instance, industries and factories are contributing largely to pollution. They are deteriorating the quality of air that we breathe and the water we consume.

Thus, this day serves as an eye-opener for many citizens who aren’t aware of all this. In other words, it spreads awareness amongst the common people which the environment is facing right now. Moreover, it also encourages the public from different societies and communities to take active participation in celebrating the day.

Every Little Deed Matters

On the occasion of World Environment Day, it is essential for all to realize that every little deed matters when it comes to saving the environment. No matter how small a step you are taking to lead a greener lifestyle, it does make a difference. Because, if everyone starts doing little deeds one by one, it will turn into something big. As the saying goes every drop makes an ocean, it is true in this case as well.

As there are a lot of diseases that originate due to unhygienic living conditions and dirty water, we must begin there. For instance, when water remains stagnant or unclean for long, various insects and bacteria start growing there. This results in deadly diseases like Malaria, Dengue and more. So, we must make sure to cover the tanks, pots, coolers and more which may become a breeding ground for such insects and diseases.

Similarly, we have to talk about the issues of garbage disposal. Especially in our country, people litter around everywhere. It is essential to firstly dispose of waste properly and also segregate the wet and dry waste accordingly.

These little deeds will make you realize how wholesome your life will become. It is not always about the money and luxury, the little fulfilling things and change in habits can also prove to be very effective.

Thus, we have the World Environment Day which serves as a reminder to protect the environment at all costs. All the resources of nature from forests to oceans and soil to air, we must conserve.

To sum it up, always remember that the gifts and blessings which nature endows on us are priceless. It is rather essential to conserve them all for a better future and life for all. Always remember that small steps will help you reach your goal.
