3.  Pollution
is the introduction of contaminants
into a natural environment that cause
adverse change.
 Pollution can take the form of chemical
substances or energy such as noise, heat or
light.

4. There are four types of pollution
 Air
Pollution
 Water
 Land
 Noise
Pollution
Pollution
Pollution

6. Air pollution is the introduction into
the atmosphere of chemicals, particu
lates, or biological materials that
cause discomfort, disease, or death
to humans, damage other living
organisms such as food crops, or
damage the natural
environment or built environment.

7. The pollution of air can be caused by natural processes or by human activities. The
sources of air pollution are classified into two groups:

Natural Sources

Man made sources
Natural Sources of Air Pollution: They are dust storms, forest fires, ash from
smoking volcanoes, decay of organic matters and pollen grains floating in air.
Manmade Sources of Air Pollution: They are population
explosion,deforestation,urbanisation and industrialisation, whose effects can be
explained as follows:

Burning of fuels like wood, cow dung cakes, coal and kerosene in homes pollute the
air.

Exhaust gases emitted by motor vehicles which pollute the air are the major source
of air pollution in big cities.

Industries pollute air by releasing various types of pollutants such as sulphur
dioxide, oxides of carbon,nitrogen oxide,chlorine,asbestos dust and cement dust.

Thermal power plants pollute air by emitting sulphur dioxide and fly-ash.

Nuclear power plants pollute air by releasing radioactive rays.

8. Acid rain
 Green house effects
 Smog
Short-term health effects:
 Irritation to the eyes, nose and throat.
 Upper respiratory infections such as bronchitis and
pneumonia.
 Asthma
Long-term health effects:
 Chronic respiratory disease.
 Lung cancer
 Heart disease
 Even damage to the brain, nerves, liver, or kidneys.


9. 
Tall chimneys should be installed in factories.

Better designed equipment and smokeless fuels
should be used in homes and industries.

Renewable and non- polluting sources of energy like
solar energy, wind energy,etc,should be used.
Automobiles should be properly maintained and
adhere to emission control standards.


More trees should be planted along roadsides and
houses.

10. Water pollution

11.  Any
change or modification in the
physical, chemical and biological properties
of water that has a detrimental consequence
on living things is water pollution.

12.  About
40% of deaths worldwide are caused by
water pollution
 Water pollution is caused by organic and
inorganic industrial waste discharged in
water.
 Sewage and waste water.
 Oil leakage from ships.

13.  Diseases
like Cholera
 Aquatic life gets destroyed
 Affects food chain
 Cause algae
 Less pure water to drink

14.  Rivers
should not be used for washing clothes
or bathing animals in.
 Dams should be created.
 In sacred rivers like Ganga dead bodies
shouldn’t be thrown.

16.  Land
pollution is the degradation of the
earth’s surface and misuse of land resources
often caused by human activities.

17.  Throwing
garbage
 Construction
 Waste
 Industrial waste
 Mining

18.  Agriculture
 Littering
 Climate
 Biodiversity

19.  More
and more land should be brought under
farming.
 Trees should be planted everywhere.
 Waste matter should be disposed
immediately
 Avoid drilling lands for underground water.
 Avoid using fertilizer and pesticides for
farming.

21.  Noise
pollution is excessive, displeasing
humans or animals or machine created noise
environmental that disrupts the activity or
balance of humans and animals.
 Noise pollution not only results to irritation
and anger.

22.  Traffic
noise
 Air craft noise
 Noise from construction and civil engineers
work.
 Noise from industries
 Noise from other sources

23.  Hearing
loss
 Sleep disturbances
 High blood pressure
 Stress

24.  The
government should ensure the new
machines are noise proof.
 Airports should be away from residential
areas.
 ‘No horn’ boards should be put on/near
school areas.
 We should talk less and work more.

25. According to me, many living things in the environments
around the world are affected by degradation, including
animals. Animals play a very important role in our
environment, and with degradation killing many animals, we
are running into a problem. From lack of food, many animals
die of starvation. Animals lose shelter and food sources
because of degradation. Pollution can hurt the animals in the
environment, even when we just leave plastic pop holders out
on the ground, which animals can choke on. Animals are also
affected by many kind of pollution, including air pollution
which basically suffocates them to death. Animals' shelters and
food sources are destroyed not only by humans, but by natural
degradation . during winter, salt is distributed on the roads, but
some goes on the sides of the roads, and when animals eat
plants that are contaminated with the salt, they may get
severely sick, or even die. When there is overpopulation of
livestock, that can cause overgrazing, which is a way to cause
land degradation .Degradation in areas such as the rainforest
cause many animals to not only lose food supply and shelter,
but their lives.
