3. INTRODUCTION
 There was a time when people thought of the
environment, they thought of its beauty; but now as
the natural beauty of the earth that disappears, many
people around the world have awoken to the realities
of just how fragile our earth actually is. Central to
this issue is pollution, which involves the
introduction of harmful substances into the
air, land, and water. Although pollution has been
occurring throughout the earth’s history, the rate by
which the human species have contributed to the
amount of pollution that has entered our environment
over the past several hundred years far exceeds the
earth’s inherent ability to heal itself.

4.  Along with pollution, the mass
deforestation of the world’s old growth
forests has also posed a growing problem to
the health of our environment. The
clearance of forests without sufficient
reforestation has gradually wore down
nature’s natural defense against air
pollution, desertification, and soil nutrient
loss to the point that we are now facing a
future world without trees, which would
ultimately mean a world without people.

5. • The global issue of the Environment encompasses
many diverse matters of interest some of which will be
discussed throughout this environment
presentation, which include: global warming, ozone
depletion, Extinction of plant and animal species. But
it is also important to take measures to avoid the
danger of mass devastation which will also be discussed
in this ppt.

7. OZONE LAYER
DEPLETION
Why the hole in the atmospheric ozone layer
above us?
What has been done about this?
Why should I worry ourselves about the
Ozone Layer Depletion?

8. Good life at the beach threatened?
Mr. OZONE: Will I be able to continue
enjoying this life without problems?

9. What is Ozone? Ozone Layer?

10. CFC’s and ozone depletion

11. Global CFC production

12. Ozone hole measurements over the
Antarctic region 1980-98

13. Effects of UV rays on Aquatic
Ecosystems

16. MEASURES TO BE TAKEN

18. GREENHOUSE EFFECT

19. DEFORESTATION HAS LED TO A DRASTIC INCREASE IN CO2 LEVELS.

25. WATER IS THE MOST
PRECIOUS COMMODITY ON
THE EARTH.IT HAS MADE
HUMAN LIFE POSSIBLE ON
THE EARTH.IT IS USED FOR
VARIOUS PURPOSES ACROS
THE GLOBE.HUMAN
LIFE,FLORA AND FAUNA ALL
CHERISH UNDER ITS EFFECT.

26. Nowadays especially in our country
people have no value of water or the are
not aware of the importance of water .
People are throwing garbage in rivers,
lakes etc .They are using water very
irresponsibly they don’t care about their
future. This of course makes the river
dirty.

28. Causes of pollution of water.

30. FORESTS ARE LARGE GROUPS
OF TREES .IN WHICH
HABITANTS ARE LARGE
VARIETY OF ANIMALS RANGING
FROM SMALL RATS TO MASSIVE
BODIED ELEPHANT .FORESTS
PROVIDE US WITH
TIMBER,MEDICINES ETC.
HENCE THEY ARE VERY
ESSENTIAL TO US.

31. But now a days people are cutting these
beautiful forests for their greed of land.
This leads to deforestation.
Deforestation not only reduces the green
cover but also reduces the concentration
of oxygen in the air .With out forests
the earth would become an easy prey for
global warming which could kill all of
us.

32. DEFORESTATION

33. EFFECTS OF DEFORESTATION

36. • The Scarlet Macaw is found in the
treetops from Mexico to southern Brazil.
It is about 90 centimetres in length and is
bright red with blue and yellow wings,
blue and red tail which is a unique feature
in the family and a white face with big,
sickle-shaped beaks. Its feet are able to
grasp the limbs of a tree very firmly.
When a Macaw is fully developed, the tail
is more than two feet long.
• WHY ARE MACAWS ENDANGERED ?
• BECAUSE THE FEMALE WILL NOT LAY ANOTHER
GROUPS OF EGG UNTIL THE FIRST GROUP IS
INDEPENDENT .THIS MEANS THAT THE
POPULATION DOES NOT GROW QUICKLY.
• THIS IS A BIG PROBLEM BECAUSE THESE ARE
OFTEN KILLED OR CAPTURED BY HUMANS AS
PETS .

38. •
KOALAEastern Australia. It is a
Koalas are found in the coastal regions of
marsupial mammal. It is endangered because-

39. GIANT PANDA (ASIA)
Pandas are dying out mainly because of one main
reason: habitat loss. Their main source of food is
bamboo, which takes a long time to grow.
Hence, when a forest of bamboo was being
consumed by them they could simply move to
another bamboo forest, but as the forests have
been cut down the Pandas are experiencing
shortage of food.
Wild pandas have been reported to die because
of starvation simply because they cannot reach
the next bamboo forest quickly enough, or at
all. Habitat fragmentation affects their
feeding, and mating as well, anytime the Panda
has to leave their territory, they are at risk

40. ABOUT
• The White rhinoceros is one of the largest Northern
subspecies ever to be described by scientists. This
subspecies was classified in 1908. Today, it is very
close to extinction in the wild, and few have ever been
brought into captivity .
WHY IS RHINO ENDANGERED ?
• Rhinos are endangered because people have
been hunting them for many of years. Poaching
them just to sell their horns. They actually call the
Black Rhinos' horn "black gold" because its so
expensive....

42. The tiger is a member of felidae (cat) family. It’s length is
mostly 3.3 meters and weight is 300 kg . Tigers have a lifespan
of 10–15 years in the wild, but can live longer than 20 years in
captivity.

45. • 1 .The preservation and enhancement of wildlife and its
habitat cannot be distinguished from preservation of
human habitat and so is a core function of government.
2 .Effective habitat conservation requires the
participation of all levels of government State and federal
agencies should establish baseline data and protection
criteria as well as provide technical assistance to local
governments and landowners.
!!! IF YOU WILL NOT CONSERVE THESE ENDANGERED SPECIES THEN THESE ALL WILL
COME INTO THE CATEGORY OF EXTINCT ONE .

46. Project Tiger
Project Tiger is a wildlife
conservation movement
initiated in India in 1973 to
protect tigers. The project
aims at tiger conservation
in specially constituted
tiger reserves
representative of various
regions throughout India
and strives to maintain
viable populations of
Bengal tigers in their
natural environment.

47. CONSERVATION
OF
ENVIRONMENT

49. Polythene is the threat
to environment it
can’t be burnt it can’t
be thrown in water
and it can’t be eaten
we can’t dispose of in
any area if we dispose
it in water than it
causes water pollution
if we burn it then
release harmfull gases
and if swallowed by
cows than it causes
death

50. India should
promote the use of
solar energy
through solar
photovoltaic and
thermal systems
for power
generations. Also
integrate other
renewable energy
technologies like
biomass and wind.

51. SAVE PETROL
• Our bus stop is not miles away. Will it not be
good to exercise while reaching bus stop
rather than using a transport uses petrol or
diesel ? Wasting petrol for just walk able
distance is not wise ;
rather it is stupidity.

52. Save trees ,stop
pollution…………..
• The most important motto in a person’s life
should be about planting trees. Trees not only
add to scenic beauty but they are also very
useful. We should not cut them down, we
should rather grow more of them.

53. Save electricity
• Today is today ,tomorrow never comes save
electrcity today to generate it tommorow.we
should never forget to switch off the ligjhts
and fans .
This saves electricity.if we utilize electricity,it can
be provided to the places
where it does not reach.
it should be our motto to
Check that nobody waste it.

54. No Smoking in public
places………..
• Our other motto should be about smoking.
Smoking can be harmful so,we should not
smoke, due to smoking pollution is inc. in
environment.

55. • NATURE HAS GIVEN US WONDERFUL
GIFTS.BEING YOUNGER GENERATION,WE
SHOUL LOOK AFTER THEESE
GIFTS.THEREFORE,START PLAYING THE ROLE
OF SAVIOUR OF ENVIRNOMENT.
GOOD LUCK!
