Conclusion – One Green Day

7. temperature can have serious effects on climate
conditions & weather changes. This affect the frequency
& severity of storms hurricanes & tornados distort
seasons duration, increase cloud cover, change
precipitation levels & wind patterns. Warmer sea surface
temperature will cause frequent storms & hurricanes
along the gulf coasts & southeastern Atlantic. A number
of scientist have agreed that global warming is a serious
warming is happening more quickly in same parts of the
world than others.
The formation of the Earth took places around 4.6
Billion years ago & since then its temperature is
changing. It has been warmer in the past than it is today
& at time much colder. But the most alarming fact is the
speed at

8. which the Earth is now heating up. Before the first time
history humans are the main factor of the Earth’s
changing climate or as we have named it ‘GLOBAL
WARMING’.

9. Target of Global Warming

10. CAUSES OF GLOBAL WARMING
1. Greenhouse Effect :
The greenhouse effect was discovered on 1896
and is a natural process. To support life for billions of
years it has kept our planet warm enough. But more
heat is trapped in the atmosphere as the amount of
greenhouse gases increases. The earth is getting
hotter as the natural process has spread up.

11. GREENHOUSE EFFECT

12. 2.
LIFE IN CITY
It is not just that there are more people than ever
before. It is also how we choose to live that puts a
strain on our planet. Life is comfortable and
convenient in large cities. But the energy this lifestyle
needs has a high environmental cost.

13. LIFE IN CITY

14. 3. INCREASE POPULATION :
One of the greatest factors in global warming is the
in increasing number of people on the earth. During
the past 100 years the world's population has grown
nearly four times larger. This has led to a massive rise
in the levels of greenhouse gases in the earth's
atmosphere.
The growth of towns and cities is called urban
spread. This takes up land that could be used for food
crops and also destroys the places where plants and
animal live.

16. INCREASE POPULATION

17. 4.
AIR POLLUTION :
There are different kinds of pollution. Some visible,
some invisible, that contribute the global warming.
Carbon dioxide a greenhouse gases is the main
pollutant that is warming earth. Though living things
emit carbon dioxide when they breathe, carbon
dioxide is widely considered to be a pollutant when
associated with cars, planes, power plants and other
human activities that involve the burning of fossil.

19. AIR POLLUTION

20. 5. Deforestation :
Deforestation is clearing earth's forests on a
massive scale often resulting in damage to the quality
of the land. Forests still cover about 30% of the
world's land area.
Forests are cut down for many reasons but most of
them are related to money or to peoples need to
provide for their families. The biggest driver of
deforestation is agriculture.
Deforestation has many negative effects on the
environment. The most dramatic impact is a loss of
habitat for millions of speckles. It also drives climate
change. Forest soils are moist, but without protection
from sun blocking tree cover they quickly dry out.
The quickest solution to deforestation would be to
simply stop cutting down trees.

21. DEFORESTATION

22. OTHER CAUSES OF GLOBAL WARMING
1. Ozone Layer :
2. Methane Gas :
3. Temperature :
4. Pollution :

23. Ozone layer
The ozone layer is a layer in Earth's atmosphere
which contains relatively high concentrations of ozone
(O3). This layer absorbs 97–99% of the Sun's high
frequency ultraviolet light, which is potentially
damaging to the life forms on Earth. It is mainly
located in the lower portion of the stratosphere from
approximately 20 to 30 Km (12 to 19 mi) above Earth,
though the thickness varies seasonally and
geographically. The ozone layer was discovered in
1913 by the French physicists Charles Fabry and
Henri Buisson. Its properties were explored in detail
by the British meteorologist G. M. B. Dobson, who
developed a simple spectrophotometer (the

24. Between 1928 and 1958 Dobson established a
worldwide network of ozone monitoring stations,
which continue to operate to this day. The "Dobson
unit", a convenient measure of the columnar density of
ozone overhead, is named in his honor.

30. EFFECTS OF GLOBAL WARMING:
1. Ice is melting worldwide, especially at the earth’s
poles. This includes mountain glaciers, ice sheets
covering West Antarctica & Greenland & Arctic sea
ice.
2. Sea level rise become faster over the last century.
Sea
levels are expected to rise between 7 & 23
inches by
the end of the century & continue
melting at the poles could add between 4 & 8 inches
3. Hurricanes & other storms are likely to become
stronger
4. Species that depends on the one another may
become out of sync.

31. 5. Floods & droughts will become more common.
Rainfall in Ethiopia, where droughts are already
common, could
decline by 10% over the next 50
years. Less fresh water will be available.
6. Some diseases will spread such as malaria carried
by mosquitoes.
7. Ecosystem will change – some species will move
further & could become extinct.

32. EFFECTS OF GLOBAL WARMING

33. ACID RAIN :
Acid rain describes any form of precipitation with
high levels of nitric & sulfuric acids. It can also occur in
the form of snow, fog & tiny bits of dry material that
settle to earth.
Ratting vegetation & erupting volcanoes release
some chemical that can cause acid rain but most acid
rain falls because of human activities. The biggest
culprit is the burning of fossil fuels by coal burning
power plants factories & automobiles.
Acid rain has many ecology but none is greater
than its impact on lakes, streams, wetlands & other
aquatic environments. Acid rain makes water acidic &
causes them to absorb the aluminum that makes its
way from soil into lakes & steams. This combination

34. crayfish clams, fish & other aquatic animals
The only way to fight acid rain is by curbing the
release of the pollutants that cause it.

36. DISAPPEARING WORLD:
Many nations have laws offering protection to
conservation reliant species: for example, forbidding
hunting, restricting land development or creating
preserves. Before greenhouse gases and global
warming species were able to survive in their natural
habitat. However the rapid increase of climate change
has put animals at risk of becoming extinct. As global
warming continues, species are no longer able to
survive and their kind starts to deteriorate. This is a
repeating cycle that is starting to increase at a rapid
rate because of climate change therefore landing
many species on the endangered species list.

46. ECO-FRIENDLY HOMES:
Our home release almost a third of the
greenhouse gas we produce. The good news is that
there are several ways ranging from now our homes
are built to the way we live inside them. By which we
can reduce the amount of greenhouse we make.

47. ECO-FRIENDLY HOMES

48. Preservation of Forests and Oceans:
Carbon is removed & trapped by the forest &
oceans as part of their natural process. In turn they
can decrease the amount of carbon dioxide in the
atmosphere & limit the power of the greenhouse
effect. Humans have upset earth’s natural balance by
damaging forest polluting oceans & fossil fuels. Due to
this reason we must work together to protect our
precious trees & seas.

49. Preservation of Forests and Oceans

50. LESS WASTE:
A large amount of our household waste ends up on
solid waste landfills. These enormous trash dumps
release methane a greenhouse gas as they vote. One
easy was to cut the methane that is released is to
reduce the amount of trash you produce & recycle as
much as possible of what is left.

51. Less Waste

52. What can you do Prevent Global Warming?
1. Recycle as much waste as is possible by sorting
your
trash.
2. Compost all your food scraps for use in your
garden.
3. Take used glass bottles & jars to a recycling
centre.
4. Save & reread old comics & amazing or give them
to a friend.
5. Donate old toys & cloths to thrift stores.

53. CONCLUSION:
One Green Day
By saving water & electricity each one of us can
held fight climate change. You can go even fate a
difference. The clothes you wear the foods you eat &
the product you use all contribute to your personal
carbon foot print simple everyday decision can make
a huge difference to the amount of the greenhouse
gas that your lifestyle contributes to our atmosphere.
