3. CONTENT OF ENVIRONMENTAL POLLUTION
 Introduction
 Kinds of environmental pollution
 Effect of environmental pollution
 Causes of environmental pollution
 Prevention of environmental pollution

4. INTRODUCTION OF ENVIRONMENTAL POLLUTION
Our environment is a major aspect of our life today. Many
of us don't take our Earth seriously and think that as long
as pollution doesn't hurt them they can go ahead and
throw garbage on the ground or spill oil down the drain.
Well to many people have that theory and they are killing
off our Earth and also physically harming themselves
from the air they breath and the water they swim in. Our
Earth is fragile like a human and people don't know.

5. DEFINITION OF ENVIRONMENTAL POLLUTION
Environmental pollution is the build-up and concentration
of toxic levels of chemicals in the air, water, and land,
which reduces the ability of the affected area to support
life. Pollutants may be gaseous- ozone and carbon
monoxide, for example; liquid discharge from industrial
plants and sewage systems; or solid-landfills and
junkyards.

6. KINDS OF ENVIRONMENTAL POLLUTION
There are actually SEVEN different kinds of
environmental pollution. Most people can name
them are;
o Air pollution
o Land pollution
o Water pollution
o Noise pollution
o Light pollution
o Thermal pollution
o Visual pollution
Listed below are each kind and examples to help you
understand just how we can affect the environment
and each other.

7. AIR POLLUTION DEFINITION;
AIR POLLUTION IS THE CONTAMINATION OF AIR BY SMOKE AND
HARMFUL GASES, MAINLY OXIDES OF CARBON, SULFUR, AND
NITROGEN.

8. EXAMPLE OF AIR POLLUTION
Some examples of air pollution include:
 Exhaust fumes from vehicles
 The burning of fossil fuels, such as coal, oil or gas
 Harmful off- gasing from things such as paint, plastic
production and so on
 Radiation spills or nuclear accidents
 Air pollution is linked to asthma, allergies and other
respiratory illnesses.

9. CAUSES OF AIR POLLUTION
Major sources of air pollution are;
o Industries
o Smoke
o Mist
o Carbon black
o Aerosols
o Dust
o Automobiles and domestic fuel
o High proportion of undesirable gases

10. EFFECT OF AIR POLLUTION
Air pollution effect?
 Human health
 Animal
 Plants
 The atmosphere
 Global warming
 Acids rains
 Ozone depletion
 Various respairatly illness

11. PREVENTION OF AIR POLLUTION
Air pollution prevention?
 Local controls
 Dark smoke
 Boilers and furnaces

13. EXAMPLE OF LIGHT POLLUTION;
Some examples of what causes light pollution:
 Street lamps that shine light in all directions, instead of
with a hood to point light downward toward the street.
 Unnecessary lights, especially around the home
Light pollution uses more energy (by shining more light up
instead of down), may affect human health and our sleep
cycles and most importantly, corrupts our kids telescopes
and their curiosity.
Wastage of light pollution

14. CAUSES OF LIGHT POLLUTION

15. EFFECT OF LIGHT POLLUTION;

16. PREVENTION OF LIGHT POLLUTION;

17. LAND POLLUTION DEFINITION;
Land pollution is the degradation of the Earth's surface
caused by a misuse of resources and improper disposal of
waste.

18. EXAMPLE OF LAND POLLUTION
Some examples of land pollution include:
 Litter found on the side of the road
 Illegal dumping in natural habitats
 Oil spills that happen inland
 The use of pesticides and other farming chemicals
 Damage and debris caused from unsustainable mining and
logging practices
 Radiation spills or nuclear accidents

19. CAUSES OF LAND POLLUTION
Four main causes of land pollution are
 Construction
 Agriculture
 Domestic waste
 Industrial waste

20. EFFECT OF LAND POLLUTION
These are the effect of land pollution;
 The land cannot used to built houses
 Man cannot farming
 Ground water will get effected
 Death of the animal that inhabit the land

21. PREVENTION OF LAND POLLUTION
 Good agriculture practice
 Trees should be planted everywhere
 Waste matter should be disposed immediately
 Remediation of polluted soils
 Avoid using more fertilizers
 prevention of erosion and silting
3R PRINCIPAL
REDUCE
REFUSE
RECYCLE

22. WATER POLLUTION DEFINITION;
Water pollution is the contamination of any body of water
(lakes, groundwater, oceans, etc)

23. EXAMPLE OF WATER POLLUTION
Some examples of water pollution:
 Raw sewage running into lake or streams
 Industrial waste spills contaminating groundwater
 Radiation spills or nuclear accidents
 Illegal dumping of substances, or items in bodies of water
 Biological contamination, such as bacteria growth

24. CAUSES OF WATER POLLUTION
 Agriculture waste water
 Oil spills
 Mining
 Trash on common roads
 Refineries
 Industries process
 Natural factors effect ground water

25. EFFECT OF WATER POLLUTION;
 Malaria
 Diseases like cholera
 Typhoid (spread during the rainy season)
 Aquatic life gets destroyed

26. PREVENTION OF WATER POLLUTION;
 Factories should not throw there waste in water bodies
 People should not bath and wash clothes in rivers and
lakes
 People should not take there animal to take bath in rivers
or lakes

27. NOISE POLLUTION DEFINITION
 Noise pollution is any loud sounds that are either
harmful or annoying to humans and animals.

28. EXAMPLE OF NOISE POLLUTION
 Some examples of noise pollution:
 Airplanes, helicopters and motor vehicles
 Construction or demolition noise
 Human activities such as sporting events or
concerts

29. CAUSES OF NOISE POLLUTION
 Traffic noise
 Air craft noise
 Noise from construction
 Noise from the industries
 Noise from the other sources

30. EFFECT OF NOISE POLLUTION
 Herring loss
 Stress
 High blood pressure
 Sleep disturbance
 Colour blindness

31. EFFECT OF NOISE POLLUTION

32. PREVENTION OF NOISE POLLUTION
 Pleasant home
 We need to talk sweetly to other
 Talk less more work
 Sound effect of ears so loud noise should be avoided
 Bhagvan baba says that ‘’ silent is god’’

33. THERMAL POLLUTION DEFINITION;
 Thermal pollution is the increase of temperature
caused by human activity.

34. EXAMPLE OF THERMAL POLLUTION
 Warmer lake water from nearby manufacturing
(using cool water to cool the plant and then pump
it back into the lake)
 Included in thermal pollution should also be the
increase in temperatures in areas with lots of
concrete or vehicles, generally in cities

35. CAUSES OF THERMAL POLLUTION

 Decrease in productivity of the water body
 Changes in migration time and pattern may be effected
 Death of steno hermetic animals
 production of heat shock
proteins for thermotolerance.

37. PREVENTION OF THERMAL POLLUTION

Visual pollution is what you would call anything
unattractive or visualizing damaging to the nearby
landscape. This tends to be a highly subjective topic, as
we all find different things attractive and unattractive.
