Air pollution is increasing day by day and it has become a major cause of concern for all of us globally. Our government and the ecologists are working towards combating the situation. So let’s do our bit by writing informed speeches on the subject of air pollution. You may be asked to deliver a speech in school for students or maybe in a college and then at a higher level you may be required to address the public on stage enlightening them about the various causes of air pollution.
Long and Short Speech on Air Pollution
Good Morning Class Teacher and All My Dear Friends! Today, as you all know is Wednesday and the speech-giving day and my speech topic is Air Pollution.
Since air pollution has become an alarming issue these days; air pollution is defined by W.H.O. (World Health Organization) as “the presence in the air, of substances put there by acts of man in concentrations sufficient to interfere with the comfort, safety, or health of man or with the full use or enjoyment of his property. The presence of contaminants in the atmosphere is considered to be insufficient quantities and duration, to cause them to be injurious to human health, animal and plant life and reduce welfare in general.”
There are two main causes of air pollution, i.e. Man-made Cause and Natural Causes.
a) There are several factors affecting air pollution, such as we have chemical factories, refineries of petrol, industries of textile, paper, and pulp, etc. Besides, the industries as small as that of the brick-making as well as foundries also play a huge role in causing air pollution.
b) Several pesticides are spread on the fields. This spraying of pesticides increases the level of chemicals in our atmosphere and causes pollution in the atmosphere.
c) An increase in the number of vehicles on the road is yet another major cause of air pollution, particularly in the big cities. There are other major causes, such as old, worn-out vehicles running on the road, long-minute traffic congestion, uneven roads, and improper traffic management authority.
d) Those people who in slums or small towns do not have properly ventilated homes and when they use such methods of cooking as wood and coal in their household stoves – they further contribute to causing air pollution. And this happens in the underdeveloped nations. We shouldn’t have smoky indoor air for an obvious reason that it would affect the health of both small children and adults.
e) The power stations are mainly run on petroleum or coal so that they can generate power and heat which in turn emanates sulfur dioxide (SO2) along with the smoke. As per the studies, the thermal power stations release nearly 2/3rd of the total SO2 released in the atmosphere. These gases are really toxic to our atmosphere and cause air pollution.
f) As a matter of fact, mining activities are also one of the major factors causing air pollution because underground activities such as these generate a lot of dust. During mining, the dust gets released from stockpiles, blasting excavation, transportation of ore, crushing, etc. The situation is further aggravated when the wind blows and it takes away the dirt from one place to the other.
Just like man-made causes, there are natural causes of air pollution too, such as dust storms, forest fires, volcanic eruptions, spores of the fungus, flowers’ pollen grains, etc.
However, we can control air pollution through various means, such as Plantation, i.e. by planting more and more trees and secondly by using compressed natural gas (CNG) and unleaded petrol. We can also look for some alternative energy sources which are environment-friendly or causes little harm.
With this, I bring my speech to a close, thanks to everyone for patiently listening to me!
Hello Friends – Welcome to yet another speech giving assembly!
I hope you all are doing well! As we know that the topic which needs to be addressed today is Air Pollution and I want the participation of each one of you because everyone, including me, is responsible for causing air pollution.
We do not live and breathe in a pure environment – the air is polluted, water is contaminated, food is polluted and what not! And unfortunately more than the natural factors, it’s the human agency which is primarily responsible for causing air pollution. The air that we breathe has become so toxic these days that half of the illnesses caused to us is primarily due to the polluted environment.
The human agencies responsible for causing air pollution can be divided into various categories, but those chiefly responsible are those caused by the automobiles and the industries.
Automobiles are a serious threat to our environment and in the last decade, the pollution caused due to these vehicles has increased manifold in the Metropolitan cities, such as Delhi, Mumbai, Kolkata, Chennai, and Hyderabad. The exhausts that are emitted from the vehicles are particulate matter, carbon monoxide, nitrogen oxides and unburnt hydrocarbons, including a few carcinogenic organic compounds, such as polyaromatic hydrocarbons and benzene – which cause a serious impact on our health.
The government should encourage the use of public transport and there should be a separate lane for bicycles to ply. People should be urged to walk a few kilometers rather than riding a personal vehicle. These small, small measures can cause a significant change in the quality of air.
But did you know that there are certain other conditions affecting the emission of gases from the vehicles and lead to more air pollution. These are lack of maintenance of these vehicles, when they are old and obsolete, due to cramped roads and also because of the poor management system.
The pollution is increasing not only because of the increasing number of vehicles on the road but also due to the reasons mentioned above. It is therefore required of us to ensure the maintenance and inspection of these vehicles from time to time in order to keep a check on the emission rate when the vehicle is out on the road. There are certain testing centers, such as AETCs, i.e. The Auto Emission Testing Centers that play a significant role in keeping a check on the emission rate of the in-use automobiles.
Industrial pollution is yet another major source of air pollution. Industrial pollution not only causes water pollution but also deteriorates the quality of air. It is because of the huge expansion of the industries and machines replacing the manual labor that the quality of air has become even worse.
Immediate steps need to be taken to combat the situation of rising air pollution otherwise a time will come when we will not even be able to breathe and no life would be imaginable on this planet. So let’s save our Mother Earth and prevent the air from becoming further toxic.
I hope, through my speech, I could stir the sentiments of a lot of people and make them realize as to where we are going wrong.
This is all from my side, thank you!
Good Morning Ladies and Gentlemen – It’s good to see you all for this national conference.
However, before we begin this conference, I would like to take a few minutes of yours and address a very important issue which is in fact a point of discussion today, i.e. Air Pollution. Air pollution is no longer a problem of our country but has rather become a global phenomenon and we human beings are majorly responsible for this disaster.
Please let me be very honest and say that we are the most selfish race on this earth as we only think of ourselves and work towards making our lives comfortable. We have constructed these big factories to manufacture products and also vehicles in order to travel faster from one place to the other. Technology is really a boon for us and they have made our lives comfortable; however, the cost that we have paid in return is really massive.
Ladies and Gentlemen, the air is the most abundant natural resource available to us and we are not able to assess its worth so much so that we pollute this very air which we breathe. This is the reason why air pollution has become a huge concern these days. Government and environmentalists are trying their best to bring down the level of air pollution, but this is not an overnight change as it’ll require both time and effort on their part to bring about a change in society and make people adopt a pristine lifestyle which our ancestors lived.
Other than emission from the vehicles, there are several other man-made activities that heavily contribute towards air pollution and global warming, such as Deforestation, Mining, Agriculture, a power plant which we run on fossil fuel, etc. In fact, smoking also significantly contributes to causing air pollution. Don’t be surprised? A smoker is responsible for adding nearly 40 carcinogens to the environment using only one smoke. Even though it’s a micro-level pollutant yet its harmful effects are no way less than the macro-level pollutants.
It’s an alarming time now as air pollution has become one of the chief reasons behind the declining health status of the people. Right from causing respiratory problems such as COPD, i.e. Chronic Obstructive Pulmonary Disorder to bronchitis, cancer, heart ailments, skin cancer, allergy, asthma, etc pollution has caused great havoc in the lives of the people.
Cough, cold and pneumonia are some of the diseases which almost every other man suffers from, your next door. Isn’t it? Pollution is also slowly and gradually destroying our immune system so much so that we have become prone to various other health problems.
The time is demanding and we must adopt some concrete measures in order to check air pollution and improving life on earth. With this, I rest my speech!
Now, may I please request our board of director Mr. …… to come on the other side of the podium and say a few words in this regard.
Respected Principal, Vice Principal, Teachers and My Dear Friends – Warm Greetings to one and all!
I – Sakshi Tanwar from Class-XII (B) – welcome everyone to our school auditorium. As you know that today we are celebrating World Environment Day by planting more trees and putting up banners around our school in order to spread awareness about how important it is for us to protect our nature and save the environment from the rising pollution.
However, as I stand today in front of you, I wish to deliver a brief Speech on Air Pollution. The issue of air pollution has become a global concern now as it has reached an alarming stage and this is not good news particularly for those suffering from certain respiratory conditions, such as asthma or those who are above 65 years of age.
Other than anthropogenic (man-made) activities that are responsible for causing air pollution; the season of summer has also a major role to play. As the temperatures soar, exhaust from cars, trucks, and buses, including the common airborne particles from power plants react with sunlight and heat to produce ground-level ozone. Ozone, as we all know, poses a serious issue to our health, especially those who are heart patients or are suffering from respiratory diseases such as COPD and asthma.
Air pollution can exacerbate the problem of asthma or even can aid in its development in people who aren’t suffering from it. Isn’t that worse? Ozone acts as an irritant which can further impact the functioning of the lungs of those who are already suffering from certain respiratory conditions. One more important fact to note that the particulate matter and Nitrates which are a byproduct of combustion engines, found particularly in trucks and buses can cause severe asthma attacks.
The quality of air is deteriorating day by day and more so because we are chopping off trees which release oxygen in the atmosphere. We are not just cutting these trees, but effacing from the earth a vital source of life on earth. Deforestation is happening for many reasons such as for commercialization, urbanization or industrialization – the reason could be many, but we are causing serious harm to our environment and are also putting our lives in danger.
On top of it, when our farmers burn the waste crop, they also contribute a lot to the rising air pollution by releasing harmful gases to the environment. Likewise, we also have cases of unlawful burning of garbage.
All these activities are really threatening for our environment and the government needs to take strict measures in order to combat the situation. This is all from my side!
Now, may I please invite on stage Mrs. ………… who is our Social Science Teacher and I am sure she must have something really useful to share with us today. Everyone, please welcome her with a huge round of applause.
Thank you for being such a wonderful audience, enjoy the day with us today!
