Causes of Air Pollution
Major sources of Air Pollution
-Automobiles and Domestic fuels
-High Proportion of undesirable
gases, such as sulphur dioxide and
Effects of Air Pollution
• Air Pollution
• Human health
• The atmosphere as
Yes, we can avoid pollution As Follows
How to Avoid Air Pollution ?
• Use natural Gases, like LPG
• Do not Burst Crackers
• Use less Amount of Fuel for
• Avoid using gas stoves and use
Throwing trashes in water.
Throwing low batteries in water, lakes,
The chemicals from factories that might
flow to rivers.
Effects of Water Pollution
Diseases like Cholera
Typhoid (spread during the rainy season )
Aquatic life gets destroyed
Effects of water pollution
High blood pressure
How to Avoid Water Pollution ?
Rivers should not be used for washing
clothes or bathing animals in.
Harvesting of Rainwater to meet water
Dams &embankments must be created.
The rivers must not be contaminated.
In sacred river like Ganga the dead bodies
Sound pollution or environmental noise
is displeasing human or machine
created sound that disrupts the activity
or happiness of human or animal life. A
common form of noise pollution is from
transportation, principally motor
Causes of noise pollution
The main sources of noise pollution
are as follows:-
1. Transportation:-aircraft , trains ,cars
2. Traffic jams
3. Special events:-loudspeakears
Effects of Noise Pollution
High Blood Pressure
How to Avoid Noise Pollution ?
The Government should ensure the new
machines that Should be noise proof.
Air ports must be away from residential
The Sound horn symbol is to be in School
Prevention of Noise Pollution
We need to talk sweetly to others.
Talk Less Work More.
Sound affects our ears so loud noise
should be avoided.
Definition of Land Pollution
One fourth of area is covered by land is
Called Land .
Land is a earth which is occupied by
people for shelter, occupation etc..,
Causes of Land Pollution
We can classify major sources that lead to
land following Categories
Mining and quarrying
Effects of Land Pollution
The Land Cannot be used to construct
Farmers cannot do farming
Ground water will gets Affected
Prevention of Land Pollution
More and more land should be brought
Trees should be planted everywhere.
Waste matter should be disposed
Avoid drilling the Land for more
Avoid using more fertilizers and
The Carrot Approach to
This approach involves offering advice to
companies about pollution and waste to encourage
them to cut back voluntarily. People are needed to
be educated about the Three Rs:
Reduce: Cut back on amount used and the waste
Recycle: Recover waste products and make them
into new material.
Reuse: Use items again and again (such as
polythene bags and glass bottles).
Seeking alternatives to fossil
Burning fossil fuels is the main cause of air pollution, both
local and global. This suggests that replacing fossil fuels with
clean renewable and sustainable sources of energy would
do the most to reduce pollution in the world.
Alternative energy sources are as follows;
1. Hydroelectric (hydel) power from fast
2. Wind power using tall turbines driven by
force of the wind.
3. Solar power using tall turbines driven by force of winds.
4. 4. Solar power by using solar panels and PVs (photovoltaic
5. Geothermal power making use of heat from the ground,
particularly in volcanic areas.
6. Wave power using movement of the sea and breaking
HEP is the only alternative which is widely being
It accounts for 6 % of worlds energy consumption and
for about 13% of energy use in Pakistan.
In Pakistan most of comes from the large northern
dams. Dams are needed for 2 reasons,
1. To provide a store of water for use all year.
2. To provide the force of water needed to drive the
turbines, which produce electricity in the power
In Pakistan dams are not only build to generate
electricity but there water is also used for irrigation
Water passing through a power station is neither
used up nor contaminated so that can still be used
further south of Pakistan for irrigation and drinking.
Dams of Pakistan
1. Terbela dam
2. Mangla dam
3. Rawal dam
4. Gomal dam
5. Warsak dam
Why more alternatives are not being
They are more expensive than fossil fuels.
The sun does not shine all the time.
Strong winds may not blow.
Many places are not volcanic.
Nuclear energy is not a completely safe option: a
disaster such as at Chernobyl causes immediate as
well as long lasting damage. The effects of the
radioactivity in surrounding soil and water cause long-
Pollution is a life killer and It •is true that
Pollution has made some disastrous
effects. Pollution is becoming closer to put
life on the verge of death and It has killed
many lives already. So, as a human, we
should stop pollution and join a program or
that involved of Pollution Prevention.
