(ବାୟୁ ପ୍ରଦୂଷଣ ନିୟନ୍ତ୍ରଣର ଉପାୟଗୁଡ଼ିକ କ’ଣ ?)
Answer:
There are three basic ways to control air pollution preventive measures, dispersal measures and collection measures. Preventive measures can be taken by changing the raw materials used in industry or the ingredients of fuel. Dispersal measures can be taken by raising the heights of tall chimneys of the factories. Collection measures can be taken by designing equipment to trap pollutants before they escape into the atmosphere.

Question 23.
How have different countries tried to check it?
(ବିଭିନ୍ନ ଦେଶଗୁଡ଼ିକ ଏହାକୁ ରୋକିବାକୁ କିପରି ପ୍ରୟାସ କରିଛନ୍ତି ?)

Question 24.
How have the air quality programmes brought us benefits?
(କିପରି ବାୟୁର ଗୁଣାତ୍ମକ ବୃଦ୍ଧି ସମ୍ପର୍କିତ କାର୍ଯ୍ୟକ୍ରମଗୁଡ଼ିକ ଆମର ଉପକାର କରିଛନ୍ତି ?)
Answer:
Air quality programmes have brought us benefits in many areas. For example, burning low-sulphur coal and oil in factories and power plants has lowered pollution in many cities. In order to meet standards, automobile engines are redesigned and new cars have been equipped with devices like catalytic converter which changes pollutants into harmless substances and reduces air pollution.

Question 25.
Why do we still need to find out better ways to control air pollution?
(ତଥାପି ଆମେ କାହିଁକି ବାୟୁ ପ୍ରଦୂଷଣ ନିୟନ୍ତ୍ରଣ ନିମନ୍ତେ ଉନ୍ନତ ଉପାୟମାନ ବାହାର କରିବା ଦରକାର କରୁଛୁ ?)
Answer:
Although the formulation of certain laws and set of standards and norms have checked air pollution up to some extent, it hasn’t been completely checked. So we still need to find out better ways to control air pollution. It is not easy to bring about the new development needed to control it. Now physicians, engineers, botanists and meteorologists are carrying out research, seeking new ways to check it. In the future, we can breathe pure air in the cities where the sunlight is no longer blocked by an umbrella of air pollution.

Question 1.
Why does the oxygen level in the atmosphere get reduced? What could be its consequences?
(ବାୟୁମଣ୍ଡଳରେ ଅମ୍ଳଜାନ ସ୍ତର କମିଯାଇଛି କାହିଁକି ? ଏହାର ପରିଣାମ କ’ଣ ହୋଇପାରେ ? )
Answer:
The oxygen level in the atmosphere gets reduced for many reasons. Due to deforestation, the photosynthesis process has been reduced and the amount of oxygen gets reduced. Besides burning process also reduces the amount of oxygen in the atmosphere. If it so happens then living beings will be definitely deprived of availing adequate oxygen. Besides, through respiration oxygen gets converted into carbon dioxide which traps radiation that reaches the earth from the sun, as a result, the atmosphere becomes warmer and would eventually lead to global warming.

Question 2.
How do the chemical industries cause dangerous air pollution? What are its far-reaching consequences?
(ରସାୟନ ଶିଳ୍ପଗୁଡ଼ିକ କିପରି ବିପଜନକ ବାୟୁ ପ୍ରଦୂଷଣ ସୃଷ୍ଟି କରୁଛନ୍ତି ? ଏହାର ସୁଦୂରପ୍ରସାରୀ ପରିଣାମ କ’ଣ ?)
Answer:
The chemical industries release certain toxic fumes into the atmosphere, along with smoke. It mingles with the atmospheric air and pollutes it. When people inhale that toxic substance, they suffer from serious diseases.

Question 3.
How is acid rain caused?
(ଅମ୍ଳବୃଷ୍ଟି କିପରି ସୃଷ୍ଟି ହୁଏ ?)
Answer:
Acid rain is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulphuric acid. The chemical forerunners of acid rain formation result from both natural sources such as volcanoes and decaying vegetation and man-made sources primarily emissions of sulphur dioxide and nitrogen oxides resulting from fossil fuel combustion. Acid rain occurs when these gases react in the atmosphere with water, oxygen and other chemicals to form various acidic compounds.

Question 4.
How does polluted air travel from one country to another?
(ପ୍ରଦୂଷିତ ବାୟୁ କିପରି ଗୋଟିଏ ଦେଶରୁ ଅନ୍ୟ ଦେଶକୁ ଯାଇଥାଏ ?)
Answer:

Answer:
The pollution caused by automobiles can be reduced by taking certain steps. First of all, the ingredients of fuel used in automobiles should be changed. Secondly, automobile engines should be redesigned and equipped with new devices like catalytic converters which can change pollutants into harmless substances. Yes, air pollution is a global problem. It is a problem for the whole world.

Answer:

1. Let’s think together :
The text you have read mentions some steps to reduce air pollution. Now work in groups to suggest more steps for dealing with the problem. You can refer to newspapers, and journals and discuss among yourselves to get more ideas (The teacher divides the class into four or five groups for the purpose)(This activity will be done in the class by the teacher.)

2. Let’s speak and listen :
Each group presents its ideas in class regarding the steps to control air pollution. Other groups listen and react to the ideas. After all the groups have presented ideas, commonly agreed aspects should be finalized. (The teacher acts as the observer and coordinator.) (This activity will be done in the class by the teacher.)

3. Let’s write :
Write a letter to the Editor of a newspaper / the Minister, Department of Environment explaining the importance of clean air and suggesting ways to keep it clean and pure. (ପରିଷ୍କାର ବାୟୁର ଗୁରୁତ୍ଵ ଏବଂ ଏହାକୁ ପରିଷ୍କାର ଓ ବିଶୁଦ୍ଧ ରଖିବାର ଉପାୟମାନ ବୁଝାଇ ସମ୍ବାଦପତ୍ରର ସମ୍ପାଦକ/ପରିବେଶ ବିଭାଗର ମନ୍ତ୍ରୀଙ୍କୁ ଏକ ପତ୍ର ଲେଖ ।)

Sub – Importance of clean air.

Dear Sir,

I shall be much obliged if you kindly publish this news item in your widely circulated newspaper.
Everybody needs pure and clean air in order to make his body fit. It is essential for the human body. Man can’t live even a moment without air. But it has become a dream now. Every comer of the world is filled with polluted air because of the growing industries of automobiles. When we respire the polluted air we suffer from many harmful diseases. The polluted air has caused a lot of harm not only to living creatures but also to trees and buildings.

All living creatures need pure and clean air so that they can keep themselves fit both physically and mentally. We all have to do something to keep it clean. A large number of trees should be planted every year to neutralize some pollutants. Some of the industries should be disestablished. The raw materials used in factories or the ingredients of fuel should be changed and equipment should be designed in such a way that can trap the pollutants before they escape into the atmosphere. Automobile engines should be equipped with devices that can change pollutants into harmless substances. Above all the government should pass laws to prevent and control air pollution.

Through your much-esteemed paper, I would like to draw the attention of the public as well as the government to do something to check air pollution and ensure a pure air.

Yours faithfully
Sasmita Praharaj

4. Let’s debate:
Some speak ‘for’ the motion and some ‘against’. The teacher acts as Chairperson.
(କେତେକ ପ୍ରସ୍ତାବ ସପକ୍ଷରେ ଓ କେତେକ ପ୍ରସ୍ତାବ ବିପକ୍ଷରେ କହିବେ, ଶିକ୍ଷକ ସଭାପତିଭାବେ କାର୍ଯ୍ୟ କରିବେ ।)
(i) Use of private vehicles should be banned to control air pollution.
(ବେସରକାରୀ ଯାନବାହନ ବ୍ୟବହାର ନିଷିଦ୍ଧ ହେବା ଉଚିତ ।)
Answer:
Group — A (For)
Undoubtedly the number of private vehicles used is more than the number of government vehicles. Their contribution to causing air pollution is more. It causes near about 60 per cent of air pollution. Some people misuse their vehicles. Even they take their vehicles to a very short distances. Some people use it as a luxury item. So private vehicles should be banned so that air pollution can be controlled.

Group – B (Against)
Only private vehicles can meet the demand of the exploding population. Though a number of passenger carriers and goods carriers are run by the government, they can’t meet the rising demand of the people. Government can’t provide adequate service transportation. Of course, vehicles are responsible for air pollution. But all private vehicles shouldn’t be banned. A lot of problems will arise if it is done.

(ii) Industries being the major source of pollution need to be disestablished
(ପ୍ରଦୂଷଣର ମୁଖ୍ୟ ଉତ୍ସ ହୋଇଥିବାରୁ ଶିଳ୍ପଗୁଡ଼ିକୁ ବିଲୋପ କରିବା ଆବଶ୍ୟକ ।)
Answer:
Group – A (For)
Most industries spew smoke, ash, dust and other pollutants into the atmospheric air. So the air gets polluted. It affects human beings, aquatic creatures, plants, trees as well as soil. Of course, industries fulfil the demand of the people. But they need to be disestablished to check pollution and save people and others from its ill effects.

Group – B (Against)
Modem society would come to halt without industries. Industrial products fulfil the demand of the people. Everything we use in our day-to-day life is a product of an industry or other. So the industries shouldn’t be disestablished.

(i) There are some words/phrases in the text used to convey the harmful effects of air pollution on mankind.
