• Air – conditioner:
“Air Conditioner is one of the domestic appliances, which becomes
part of our routine daily life.”
•
Three tasks of Air - Conditioner:

Temperature Controlling
Humidity Controlling
Purify the air
• Forests:
“Forests are formed by a community of plants, which is
predominantly structurally defined by its trees, shrubs, climbers and
ground cover.”
• They mainly preserve our environment green and clean by temperature
control of the air, humidity control of the air and purify the air.
• So, we can clearly say that with so much functionality, forest work as an
Air conditioner.
• To cool down ……………
 A room
- 1 Ton, 1.5 Ton or 2 Ton of capacity
- 400-500 units electricity
- Rs. 2,500 per month
- Rs. 30,000 per year
 A building
- several Lacks
 A Residency - several Crore
or a society
 City
- Rs. 3,50,00,00,00,000
[Rs. three hundred fifty billion]
[ex. Ahmedabad]
 State
- Rs.15,00,00,00,00,00,000 [Rs.150 trillion]
[ex. Gujarat]
 Country
- Rs.2,50,00,00,00,00,00,000 [Rs. 2.5 thousand trillion]
[ex. India]

• Temperature Control:

–
Shade
Ozone Layer
Reduces Global Warming
Thus, they control temp.
• Humidity Control:
– Winter - absorb the atmospheric moisture
– Summer -release the atmospheric moisture
– by the process of ‘transpiration’
• Air Purifying:
– intake CO2
– release O2
– by the process of ‘photosynthesis’
Let we learn it how they work as a natural air conditioner……
WHAT IS PHOTOSYNTHESIS ?
A process used by plants and other organisms
which includes three stages:
• Absorption of light
• Conversion of light energy into chemical energy
• Reduction of CO2 into carbohydrate molecules
The term “photosynthesis” is derived from
Greek words:
• ‘phos’ means light
• ‘synthesis’ means putting together
HOW PHOTOSYNTHESIS WORKS ?
• Although photosynthesis is performed
differently by different species, the process
always begins when energy of light is
absorbed by proteins called reaction centres
that contain green chlorophyll pigments.
• In plants, these proteins are held
inside organelles called chloroplasts,
which are most abundant in leaf cells
while in bacteria they are embedded
in the plasma membrane.
How photosynthesis is useful ?
• Maintains atmospheric oxygen
• Supplies all of the organic compounds & most of the energy necessary for life
• Average rate of energy captured is 130 terawatts – 6 times larger than current
power consumption of human civilization
• Converts 100 – 115 thousand million metric tonnes of carbon into biomass
per year
THUS, PHOTOSYNTHESIS IS HELPFUL IN ABSORBING CO2 & PURIFYING
AIR.
SO, IT PLAYS A MAJOR ROLE IN MAKING THE FORESTS WORK AS
NATURAL AIR CONDITIONER.
• Definition of Transpiration:
“Transpiration is the process of water movement through
a plant and its evaporation from aerial parts, such as from leaves, but also
from stems and flowers.”
-Leaf surfaces are dotted with pores which are called stomata, and in most
plants they are more numerous on the undersides of the foliage. The stomata
are bordered by guard cells and their stomatal accessory cells (together
known as stomatal complex) that open and close the pore.
-Mass flow of liquid water from the roots to the leaves is driven in part by
capillary action, but primarily driven by water potential differences. In taller
plants and trees, the force of gravity can only be overcome by the decrease in
hydrostatic (water) pressure in the upper parts of the plants due to the
diffusion of water out of stomata into the atmosphere. Water is absorbed at
the roots by osmosis, and any dissolved mineral nutrients travel with it
through the xylem.
• Regulation:
-Degree of stomatal opening
-Evaporative demand
-Soil water supply
-Soil temperature
-Depends on plant size

WHY SHOULD WE CONSERVE FORESTS ?
•
•
•
•
•
•
NEED FOR MORE FOOD
TO PREVENT ECOLOGICAL IMBALANCE
TO KEEP ENVIRONMENT HEALTHY, CLEAN & BEAUTIFUL
TO PREVENT SOIL EROSION
REDUCE FLOODS
ANIMALS DO NOT ENTER HUMAN HABITAT
• The main thing – To use forests as natural Air conditioner
• FORESTS COVERED 60% OF THE EARTH BUT WITH RISING
POPULATION & ITS NEED, IT HAS REDUCED TO 30%
• HOW SHOULD WE CONSERVE FORESTS ?
• TO SHARE INFORMATION WITH FRIENDS & RELATIVES ABOUT
DEFORESTATION & ITS EFFECTS
• JOIN ORGANIZATIONS & INSTITUTES THAT AIM IN CONSERVING FORESTS
• REDUCE THE USE OF ARTIFICIAL ITEMS, RECYCLE MORE & RE-USE ITEMS
WHEN MORE PEOPLE WORK
TOGETHER, THE IMPACT IS
GREATER……
THUS, IT IS CONCLUDED THAT FORESTS ARE HELPFUL FOR PLANET AND
OTHER LIVING ORGANISMS IN MANY WAYS VIZ. AIR CONDITIONER.
IT HELPS IN THE FOLLOWING WAYS:
•
•
•
•
TO SETTLE OUT, TRAP & HOLD POLLUTANTS
ABSORB CO2 AND OTHER HARMFUL GASES
PRODUCE ENOUGH OXYGEN ON EACH ACRE FOR 18 PEOPLE EVERY DAY
ABSORB ENOUGH CO2 ON EACH ACRE OVER YEAR’S TIME, TO EQUAL THE
AMOUNT YOU PRODUCE WHEN YOU DRIVE YOUR CAR 26,000 MILES
ITS NO SECRET THAT THEY MAKE URBAN ENVIRONMENT MORE PLEASANT,
IMPROVE WATER QUALITY AND ENCOURAGE US TO GET OUTSIDE FOR
EXERCISE
