Environmental pollution is the biggest menace to the human race on this planet today. It means adding impurity to environment. The environment consists of earth, water, air, plants and animals. If we pollute them, then the existence of man and nature will be hampered. Environment pollution is any discharge of material or energy into water, land, or air that causes or may cause acute (short-term) or chronic (long-term) detriment to the Earth's ecological balance. It is true that trees are being cut down rapidly, and our earth is becoming warmer. If pollution continues, the day is not far when our earth will be a boiling pan and become a desert. Or it will be covered with sea water causing destruction of mankind.

41. Water Pollution
41

42. WATER POLLUTION
 Water pollution is the contamination of water bodies
(e.g. lakes, rivers, oceans, and ground water). Water
pollution affects plants and organisms living in these bodies
of water. In almost all cases the effect is damaging not only
to individual species and populations, but also to the
natural biological communities.
42

43. CAUSES
1.Organic water pollutants
2.Inorganic water pollutants
43

44. ORGANIC WATER POLLUTANTS INCLUDE:
 Detergents
 Disinfection by products
 Food processing waste
 Insecticides and herbicides
 Chlorinated of solvent
44

45. INORGANIC WATER POLLUTANTS INCLUDE:
 Ammonia from food processing waste
 Chemical waste as industrial by-products
 Acidity caused by industrial discharges,
 Acid main drainage
45

46. WATER POLLUTION EFFECTS
 The effects of water pollution are varied and
depend on what chemicals are dumped and in
what locations.
 Boston haven is a strong example of how badly
pollution can damage bodies of water.
46

47. CONTINUED
 Many bodies of water near urban areas are highly
polluted.
 The main problem caused by water pollution is
that it kills life that inhabits water-based
ecosystems. Dead fish, birds, dolphins, and many
other animals often wind up on beaches, killed by
pollutants in their habitat.
47

48. SOLUTIONS:
 As individuals we can:
 Do not throw litter or harmful substances down sinks and
toilets. Do your part by picking up litters near rivers, lakes or
beaches and throw them into the nearest rubbish bin.
 Do not use too much fertilizer or insecticide as they will
contaminate water sources during surface runoff or when they
seep into the soil.
 Promote water conservation to friends, family and your
colleagues!
 Contact the appropriate authorities when you see water loss
through water leakages and broken pipes
48

49. CONTINUED
 The government may consider:
 Enforcing laws on industrial waste
disposal/pollution.
 Educate them on the importance of preventing
water pollution and teach them safer ways to
dispose the hazardous materials that they dump
into water sources.
 The Government can also promote water
conservation programs to institutions like schools

51. Sound Pollution
51

52. SOUND POLLUTION
Sound pollution is the exposure of people or
animals to levels of sound that are deemed to be
annoying and harmful to the ears. Noise pollution
does not encompass natural phenomena such as
thunder, but is limited to human generated noises.
53

53. CAUSES OF NOISE POLLUTION
 Industrialization
 Household Chores
 Transportation
 Construction Activities
 Social Events
53

54. EFFECTS OF NOISE POLLUTION
 1. Hearing Problems
 2. Health Issues
 3. Sleeping Disorders
 4. Cardiovascular Issues
 5. Trouble Communicating
 6. Effect on Wildlife
54

55. SOLUTIONS TO CONTROL NOISE POLLUTION
 Tree Plantation
 Soundproof Homes
 Loudspeaker Prohibition
 Factory Location
 Machine Quality
55

56. OTHER SOLUTIONS
 Noise pollution at home is caused by using music
systems and television sets with high volumes.
Instead of using these appliances with the high
volume, it is better to keep it at a moderate level.
 Sound insulation at the top of the roof can reduce
the aircraft noise.
 Add a layer of plasterboard or wood to the
dividing wall to protect yourself from the noise
from neighbors
56

57. LIGHT POLUTION
57

58. DEFINITION
Light pollution refers to the excessive and
obtrusive form of artificial light. This can include
sky glow and glare that is brought about by the
scattering of light in the atmosphere by minute
particles of dust or water.
58

59. THE LIGHT POLLUTION IN LAS VEGAS IS SO
STRONG THE CITY IS VISIBLE FROM SPACE
59

60. CAUSES
 Light pollution results from outdoor lights aimed
upward or sideways --- the light scatters in the
atmosphere and reflects back to the ground.
 The result is sky glow. Particles in the atmosphere
responsible for air pollution accentuate light
pollution by increasing the amount of light scatter.
 According to the International Dark-Sky
Association, light sources that emit blue light are
particularly disruptive to night skies due to greater
light scattering.
 No Matches Found. Please try your search again.
60

61. EFFECTS
 Wastes energy: It does not give pollution useful illumination if
the light does not fall on the right target. It is also wasted when
more light is given off than necessary.
 Clouds the night sky: City folk cant see anything except the
moon and stars in the night sky. In fact, they cannot see a host of
objects which are in the whiteout zone that can span large
stretches.
 Injures our health: Excessive light can cause many headaches,
worker fatigue, stress decrease in sexual function, and increase in
blood pressure.
 Governments should do all they can to minimize the ill-effects of
light pollution.
61

62. REDUCTION
There are ways to reduce light pollution, starting
in your own neighborhood. Make sure outdoor
lights reflect downward in what are called fully-
shielded fixtures. Also consider exchanging high-
wattage bulbs for dimmer ones and selecting
warm-white lights with low emission of blue
light. A great way to save energy and reduce
trespassing light is to turn off outdoor lights
unless needed.
62

63. VISUAL POLLUTION
63

64. VISUAL POLLUTION
Visual pollution is an aesthetic issue and refers to
the impacts of pollution that impair one's ability
to enjoy a vista or view.
Visual pollution disturbs the visual areas of
people by creating negative changes in the natural
environment. Billboards, open storage of trash,
space debris, telephone towers, electric wires,
buildings and automobiles are forms of visual
pollution.
64

65. DIFFERENT KINDS OF VISUAL
POLLUTION
 There are a lot of different kinds of visual
pollution. A few examples are: billboards with a
lot of advertisement, big windmills, ugly big
buildings and what can you invent more?
 People use these things to attract other people to
buy things or to come to their shop.
 Our opinion is that there is too much visual
pollution, and that is very ugly. It really has to be
less in the future, we hope!
65

66. THE FUTURE OF VISUAL POLLUTION
 In some cities visual pollution is a big problem, in
some cities it’s increasing and in some cities it’s
decreasing. You’ve got different kinds of visual
pollution, but it’s up to you what you think visual
pollution is.
 In these times green energy is very popular, there
come more windmills and sun panels. We think
this is visual pollution too.
66

67. CAUSES
The 3 biggest causes of visual pollution are:
1) Advertisements,
2) Green energy (windmills)
3) Innovation (modern buildings)
67

68. EFFECTS
We think the effects of visual pollution will stay
the same. In our region visual pollution isn’t a
very big problem. We think visual pollution will
decrease in the big cities, but will increase in the
areas around it. Of course we don’t know what
the future will look like but this were our
predictions.
68

69. SUMMARY
 Finally, We should never forget that the
earth is the only planet we have to live all. If
we destroy this we ourselves must be
destroyed & if we can keep the environment
of this earth healthy & beautiful mankind will
find it easy to survive embellish & develop
themselves.
