5. AIR
POLLUTION…….
Causes
Burning Of
Fuels
Exhaust Gases Others
Sulphur
Dioxide
Carbon
Monoxide
Hydrocarbons
Oxides Of
Nitrogen
Carbon Dioxide
Lead Used In
Gasoline

6. HARMFUL EFFECTS……
1. Air Pollution Is Responsible For Thousands Of Death
Every Year.
2. Old People Are Highly Vulnerable.
3. Older People With Heart Or Lung Disorders Are Under
Additional Risk.
4. Children And Infants Are Also At Risk.

8. HOW…..
1. Carbon Dioxide Reduces Amount Of Oxygen In Body Which
Causes Headache.
2. Nitrogen Oxides Causes Acid Rain, Damages Plants And
Irritates Nose-eye.
3. Carbon Monoxide Is A Poisonous Gas Which Causes Irritation,
Blackout Or Death
4. Hydrocarbons May Cause Cancer
5. Nitrogen Oxide Combines With Hydrocarbons Which Forms
Peroxyacetyl Nitrate Which Irritates Eye And Lungs.

10. PREVENTION…….
1. Factories And Industries Should Be Away From The Cities.
2. Tall Chimneys Should Be Made
3. Tetraethyl Should Be Added To Petrol Or Unleaded Petrol
Should Be Used.
4. More Growth Of Trees
5. Non Conventional Sources Of Energy Should Be Used
6. Use Of Solar Heaters, Cookers, Biogas, And Smokeless Stoves
Should Be Encouraged
7. Use Of Public Transport.

12. CAUSES
1. Atmospheric Pollution
Each Time Oxides Of Nitrogen And Sulphur Are Released
Released Into The Air, They Form Acid Rain.
This Acid Rain Falls Into Water Bodies And Contaminates
Contaminates The Water With Sulphuric Acid And Nitric
Nitric Acid.

14. CONTD…….
2. Ocean And Marine Dumping
It Is Said That Paper Takes 6 Weeks To Decompose And
Aluminium Takes 200 Years.
When This All Ends Up In The Sea, It Is Very Harmful For
All Living Organisms.

16. CONTD…..
3. Industrial Waste
Release Of Chemicals From
The Industries Cause Huge
Water Pollution With Their
Activities.

18. HARMFUL EFFECTS
1. Reduces Amount Of Oxygen In Water.
2. Results In Water–Borne Diseases. Eg: Jaundice
3. Acid Rain
4. Deals Great Damage To Aquatic Life.
5. Disruptions In Food chains
6. Damages Ecosystem

19. PREVENTION
1. Chemical Waste Should Not Be Dumped Into Water.
2. No Establishment Of Industries On Water Bank.
3. Contaminated Water Should Be Purified Before Releasing It Into
Water.
4. No Dumping Of Oil In Seas By Ships Or Tankers.
5. No Releasation Of Organic Waste Into Water Bodies.
6. Establishment Of Solar Power Stations To Decrease Thermal Power
Pollution.
7. Dams And Reservoirs Should Be Built For Controlling Flood
8. Minimum Use Of Fertilizers And Pesticides.

20. SOIL
POLLUTIONSoil
DepletionThe elimination
of minerals and
nutrients from
soil is called soil
depletion.
Soil Erosion
A process in
which the top
soil is eroded
and taken away
with either water
or wind, taking
away minerals is

21. CAUSES……
1. Domestic Waste
2. Littering Of Plastic, Glass, Other Non-biodegradable Things
3. Throwing Of Things Made Of Heavy Metal, Etc

22. FACT
The
average time
of using a
plastic bag is
just 12
seconds. So
many plastic

24. PREVENTION……
1. Less Cutting Of Trees
2. More Planting Of Saplings
3. Plants Like Bamboo And Eucalyptus Keep The Soil Firm, Thus
They Should Be Planted To Minimize Soil Erosion.
4. Plants, If Planted In A Row, Break The Force Of Wind, Thus , There
Is No Loss Of Topsoil.
5. Terrace Farming Should Be Practiced
6. Crop Rotation Should Be Followed
7. Agricultural Land Should Be Utilised At Maximum.

26. CAUSES…..
1. Jet Planes
2. Motor Vehicles
3. Television
4. Radio
5. Construction Machinery
6. Siren
7. Crackers

28. PREVENTION……
1. Reduction of noise produced by house products
2. Maintenance of automobiles
3. Low voice
4. Prohibition of loudspeakers
5. Selection of machinery
6. Maintenance of machinery

30. EFFECTS……
1. Loss Of Hearing
2. Sleeplessness
3. Depression
4. Irritation
5. Headache
6. Blood Pressure

32. THE CHIPKO ANDOLAN
In the 1970s, an organized resistance to the destruction of
forests spread throughout India and came to be known as the
Chipko movement.
The name of the movement comes from the word 'embrace', as
the villagers hugged the trees, and prevented the contractors'
from cutting them.
