3. WHAT IS AFFORESTATION...?
• Afforestation is a process of planting trees or sowing
seeds in a barren land to create a forest.
• Afforestation is the process of introducing trees and tree
seedlings to an area that has previously not been
forested.
• Afforestation is an increasingly sought-after method to
fight climate concerns, as it is known to increase the soil
quality and organic carbon levels into the soil, avoiding
desertification.
4. CONT...
• Afforestation is the establishment of a forest or stand of
trees (forestation) in an area where there was no previous
tree cover.
• Afforestation is an increasingly sought-after method to
fight climate concerns, as it is known to increase the soil
quality and organic carbon levels into the soil, avoiding
desertification.
6. WHAT IS THE NEED OF
AFFORESTATION...?
• As the deforestation and global
environmental issues due to
industrialization are growing
more seriously, there is an urgent
need for the mankind to resolve
them. So we need afforestation.
7. AFFORESTATION IN INDIA
• Total Forest Cover of India is 630 sq.km. which is
19.45 per cent of total geographical area which
states that there is imbalance in forest
management.
• India contribute :-
-18% of World Population.
-15 % of the Worlds livestock
-Just 2% of Geographical area
-Forest Area is 1% and per capita is 0.08%
which is even lower than world average of
0.8%.
• Large Scale Deforestation and non optimal
Afforestation are root and branch cause for
the present crisis.
8. ADVANTAGES OF AFFORESTATION
• A constant of forest produts like
medicine,fruits.
• Prevents soil erosion.
• Stabilizes the climate.
• Has the potential of reversing global
warming and climate change.
• Better quality Air.
• Preservation of wildlife.
• With the increasing demate.d for wood
fuels and building materials, afforestation
process helps to meet these demands
without cutting down the natural forests.
• Planting of trees in semi-arid areas attracts
rainfall.
9. CONCLUSION
• Afforestation can be done for the purpose of
commercial forestry as well as environmental
preservation.
• massive afforestation have a meaningful influence on
global climate and on mitigating the increased CO2
concentration in the atmosphere.
• Many NG/NGO directly engage in programs of
afforestation to create forests, increase carbon
capture and sequestration, and help to
anthropogenically improve biodiversity.
10. WHAT IS CFC ?
• CFC stands for Chloroflorocarbons.
• Chlorofluorocarbons, commonly known as CFCS, are a
group of man-made compounds containing chlorine,
fluorine and carbon. They are not found anywhere in
nature.
• The production of CFCS began in the 1930s for the
purpose of refrigeration. Since then they have been
extensively utilised as propellants in aerosols, as
blowing agents in foam manufacture and in air
conditioning.
11. CONT...
• The Chlorofluorocarbons (CFCS) are man-made chemicals
that exist as gases or liquids.
• They are also commonly known by the DuPont brand
name Freon.
• They are non-toxic & non-flammable in nature.
• Many CFCS have been widely used as refrigerants,
propellants (in aerosol applications), and solvents.
• They were first manufactured in 1930 under the
trademark Freon.
• Chlorofluorocarbons have lifespan in the atmosphere of
60 to 110 years.

13. SOURCES OF CFC
• The most common emitter of CFCS are refrigerants, particularly
those used after the 1930s.
• Gases containing CFCS were used for a long time as components in
aerosol cans and propellant liquids.
• Aviation regulations in some countries still require fire suppression
systems outfitted with Halon, a coolant containing CFCS.
• As refrigerants and aerosol cans containing CFCS become older and
more obsolete, people tend to forget about them, leaving them
eventually to leak and further contaminate the atmosphere.
• Chlorofluorocarbons are far less abundant than carbon dioxide in
the atmosphere, but they are 10,000 times more powerful as a
greenhouse gas and can remain in the atmosphere for more than 45
to 100 years.
14. EFFECTS OF CFCS
• Direct exposure to some types of CFCS can cause unconsciousness,
shortness of breath,and irregular heartbeat. It can also cause
confusion, drowsiness, coughing, sore throat, difficulty breathing, and
eye redness and pain. Direct skin contact with some types of CFCS
can cause frostbite or dry skin.
• CFC cause the breakdown of the ozone layer that protects the earth
from the sun's ultraviolet (UV) radiation.
• The depletion of ozone layer causes UV rays to enter earth's
atmosphere which in turn causes skin cancer, cataract and other eye
damage.
• It is harmful on its own in large enough dosage Over Exposure may
cause dizziness, loss of concentration, Central Nervous System
depression and/or cardiac arrhythmia.
15. CONT...
• Ozone shields living organisms on Earth from the harmful effects
the Sun's ultraviolet radiation.
• This can result in incidence of skin cancer in humans.
• Genetic damage in many organisms.
16. REDUCTION IN THE USE OF CFCS
• Buy air-conditioning and refrigeration equipment that do not use
HCFCs as refrigerant.
• Buy aerosol products that do not use HCFCs or CFCs as
propellants.
• Conduct regular inspection and maintenance of air-conditioning
and refrigeration appliances to prevent and minimize
refrigerant leakage.
