3. Global Warming What is it?
The word global warming mean the Rise in Global
temperature mean increase in the temperature of the
earth atmosphere and oceans which is making the
earth weather hotter day by day and damaging the
ozone layer which is causing by green house gases such
as carbon dioxide, methane, nitrous oxide and many
other gases which produce by burning the fossil fuels
such as coil, gas, oil, etc.
Research bleave that the global warming is under the
charge of 150,000 death every year around the earth
and afraid that the amount of death may be double if it
will not be in control. and also it will completely
destroy our ozone layer.

4. OZONE LAYER
It is a thin fragile shield that
envelops(cover) the earth and act
like an umbrella that absorb and
protects us from the sun harmful
Ultraviolet rays which can lead to
skin cancer. It is made up of
ozone (O3) molecules and
located in the upper atmosphere
20 to 40 kilometers above the
earth’s surface and which is so
important for our life if it damage
so life will be impossible on the
earth surface.

6. Increase in temperature
Increase in temperature the main effect of global
warming is that the intense heat waves and rising
temperature are becoming more common as
greenhouse gases are trapped in the atmosphere
experts state that this will become 100 times more
likely to occurs over the next 4 decades. The
temperature of the atmosphere is increases due to
which the climate Is being change the glashers are
melting due to which sea level is rising and many
animals such is polar bears are giving up their lives in a
large no. the storms are falling due to rise of sea level
the scientists predicate that by 2050 the arctic ocean
will be free ice and also said that in 2050, the polar
bears will only exist in zoos. If we cannot controls the
global warming.

7. Rise of sea level
when the temperature of the earth increase then
the glaciers and ice will start milting so then the
water of ice will come in the sea so the sea level will
rise then their will be disaster in the sea where the
costal area will fall into sea for which the people of
costal area will have to face many problem.

8. Health of human and animals
global warming is also a main effect on the health of
human because then the ozone layer will be hole
due to harmful gasses then the harmful ultraviolet
rays of the sun will directly fall on the human skin
which will produce skin cancer, skin dotes, skin
allergy and many more which are so dangerous
diseases for the human and also many animals are
facing such diseases and having death.

9. Disasters
 It is a big effect of global warming on the earth
which cause due to high temperature when the
temperature will be high the sea and ocean water
will evaporate and convert into vapors and they will
be form cloud so after that heavy rain fall will be so
then the many disasters will fall due to which many
populated area will be in threatened and have to
give up their live.

10. Wild life
It’s mean the life of animals and there is a big effect
of global warming on the life of animals to survive on
the earth surface because due to global warming the
temperature will rise so the glacier will melt into ice
and ice into water so there are many animals which
lives on the ice so with out ice they cannot live such
is polar bears and other many animals which need
ice for survival .and other many animals are their
which give up their live due to very high temperature
such as American pikes and due to high temperature
and dries trees cause wildfire due to which many
animals give up their life such as tiger, lion, monkey
and other many animals.

11. Forests
Forests are also effected by the global warming as
the temperature is rising day by day due to which
many type of trees and plants cannot survive in a
high temperature and many forests caught fire due
to high temperature and for which many animals
and insects which live in forests give up their live
and also due to high temperature many insects
cannot survive in forests so there are many type of
trees and plants which cannot survive with these
insects then like this the forest will decrease and the
amount of carbon dioxide increase in the world
which can increase global warming.

12. Lightening and thunder
 Lightening and thunder are big effect of global warming
which are so effective for the life on the earth when the
temperature will be high so the water of ocean and sea
will evaporate change into cloud which cause heavy rain
fall and lightening so many time lightning strike the
ground and ground and many jungles caught fire due to
which many animals and trees give up life as according to
history in 1998 all 11 member of soccer team in lightening
Africa were killed by lightening in the ground and
another light caught a child in a football ground in
Europe who got injure j and in sudden 360 reindeer were
died due to lightening. According to scientists a bold of is
5 times hotter then the surface of the sun. and also
scientists sate that there will be a 50% increase in
lightening strikes' by 2100 if it does not control.

14. • We generate electricity by electric generator then these are
operated by many source such as thermal power plant, nuclear
power plant in which we use Coal, gas, oil and uranium . when
the Coal, natural gas, petroleum oil and uranium are burn they
will produce smoke by which carbon dioxide CO2 is increase
.CO2 is main reason for destroying Ozone layer and Green
house gases. When Ozone layer is effected by these gases the
ultra violet rays directly come to earth by this the temperature
will increase. When temperature e will increase so no one can
survive on the earth surface .
• Power plants create this pollutant by burning sulfur-containing
fuels, especially diesel. Sulfur dioxide can react in the
atmosphere to form fine particles and poses the largest health
risk to young children and asthmatics.
Generating electricity by power plants

15. Transportation
 It is also a cause of global warming because in cars, motor
cycle, trains, aero planes, ships, buses etc which mostly run
on fuels, Diesels, oil, gases, Cole etc which produce Hydro
carbons {HC}, Nitrogen oxide {Nox}, carbon mono
oxide{CO},which cause lungs irritation, weaken the body’s,
by burning SO2 which cause cancer and when CO is a
poisons gas when we inhaled CO blocks oxygen from brain,
heart and vital organs newborn children and people with
chronic illnesses. Due to which the global warming is
increasing day by day.
 In 2013, transportation contributed more than half of the
carbon monoxide and nitrogen oxides, and almost a quarter
of the hydrocarbons emitted into our air.

16. Deforestation
 Now days forests are to fulfill the demand for timber and
also to obtain land for housing, highways and agriculture.
Consequently, the ecosystem is destroying day by day.
destruction of forest as a result of human activities is called
deforestation. It’s Effect on environment such as
 A result of deforestation habitats of wildlife of plants and
animals are destroyed. wildlife extinction risk is increased.
 Deforestation is one of the cause of change in weather and
climate.
 Fertile soil is lost through soil erosion
 Very long time is required for forests to grow again. they
even may not grow again.
 According to department federal bureau of statics our
forests occupied only 5% of our total area. It is too little. It is
our need to rise the area of our forests.

17. Volcanoes
 Is an opening in the surface or crust of earth which allows
hot, molten rock, ash and gases to escape from deep below
the surface.
 When volcanoes erupt, they emit a mixture of gases and
particles into the air. Some of them, such as ash and
sulphur dioxide, have a cooling effect, because they (or the
substances they cause) reflect sunlight away from the earth.
Others, such as CO2, cause warming by adding to the the
greenhouse effect.
 Plants are destroyed over a. wide area, during an eruptions
 Livestock and other mammals have been killed by lava
flows.
 Can make the temperature decrease since the sun rays are
blocked. Then the plants will die
 Stops photosynthesis from happening which keep the
plants alive.

18. LET’S

19. Role of students
Planting trees in school and streets.
Using bicycle instead of scooter and bikes.
Giving awareness to the public through rally and
issuing pamphlets and broachers.
Issuing articles about global warming in magazines.
Giving awareness to the public through radio and
media programs.
Giving seminars and presentation to the public.
One tree complete the need of oxygen of 26
children.

20. Role of public
 Planting trees more and more if you want to cut down a
tree for you need so plants two or more plants in the
place of that tree.
 Use bio-diesel in vehicles instead of fossil fuels.
 using solar energy, wind energy for generating electricity
instead of power plants like nuclear, and thermal power
plant.
 Turning light off when not using them not using them.
 Reduce the usage of refrigerator and AC.
 Keep your surrounding clean.
 Change your car and motor cycle to hydrogen power car.
 Don’t burn garbage and fusel fuel, because it makes
carbon Dioxide.
