3. *AIR SUPPLIES US WITH OXYGEN
WHICH IS ESSENTIAL FOR OUR
BODIES TO LIVE.
* THERE ARE SEVERAL MAIN
TYPES OF POLLUTION.THESE
INCLUDE SMOG, ACID RAIN
,THE GREEN HOUSE EFFECT
AND, HOLE’ IN THE OZONE
LAYER .
*ONE TYPE AIR POLLUTION IS THE
RELEASE OF PARTICLE INTO
THE AIR .
*ANOTHER TYPE POLLUTION IS
THE RELEASE NOXIOUS GASES.
*POLLUTION ALSO NEED TO BE
CONSIDERED INSIDE OUR
HOMES, OFFICES AND
SCHOOL.

4.  SMOG
* SMOG IS A TYPE OF
LARGE-SCALE
OUTDOOR
POLLUTION. IT IS
CAUSED BY
CHEMICAL
REACTION
BETWEEN
POLLUTANTS
DERIVED FROM
DIFFERENT
SOURSES.

COMBINES WITH
DROPLETS OF

* THE EFFECT OF ACID
RAIN ON THE
ENVIRONMENT CAN
BE VERY SERIOUS.

6. * IT GENERALLY COMES
FROM THE BUILD UP
OF CARBON-DIOXIDE
GAS IN THE
ATMOSPHERE.
CARBON-DIOXIDE IS
PRODUCED WHEN
FUEL ARE BURNED.
* IN THIS TYPE OF
POLLUTION SUN RAYS
GO INTO THE
ATMOSPHERE AND
THEY ARE TRAPPED
BY GREEN HOUSE
GASES. SO THE

OF POLLUTION.
CHEMICAL RELEASED

 RELEASES OF CFC
FROM HEATING,
AEROSOL
CANS,REFRIGERATION
EQUIPMENT REMOVES
SOME OF THE OZONE,
CAUSING “ HOLES”.

8. *IT IS MORE DANGAROUS
THAN THE OUTDOOR
POLLUTION, BECAUSE
WE DO EVERYTHING IN
ENCLOSED
ENVIRONMENTS
WHERE AIR
CIRCULATION MAY BE
RESTRICTED.
* THERE ARE MANY
SOURCES OF INDOOR
AIR POLLUTION:
TABACCO SMOKE,
COOKING AND
HEATING APPLIANCES
AND VAPORS FROM
BUILDING MATERIALS.

ARE OTHERS.

AFFECT OUR HEALTH
IN MANY WAYS WITH
BOTH SHORT-TERM
AND LONG-TERM
EFFECTS.

10. * The fact is that human activities contribute the
most to air pollution. Considering the
harmful effects of air pollution, now it is
very essential that everyone should
contribute a bit to prevent air pollution.
There are certain ways that one can help to
reduce the emission of air pollutants in the
atmosphere. Following are some tips for
preventing air pollution:
Car Pool: Forming and implementing a car
pool will reduce the number of cars,
thereby, preventing air pollution by cutting
down the use of fossil fuels. This way, it
will help in the sustainable use of fossil fuel
and its conservation for the future
generations.

11.  Vehicle Care: Timely servicing of the car helps to keep
it in a good condition and also minimizes fuel exhaust.
Driving the car at an average speed and turning off in
traffic is a key to save fuel. Make sure to use unleaded
petrol and opt for regular pollution checking of your
car.
Public Transport: Whenever possible, try to travel by
public transports. This helps in two ways; prevents air
pollution and increases public income. If you are going
to a nearby place, go by walking or use bicycle, instead
of using your vehicle. The objective is to minimize the
use of fuels, as far as possibl
