Global warming is caused by both natural and man-made factors such as the burning of fossil fuels. It leads to drastic climate changes, diseases, rising sea levels, food and water shortages, and species extinction. Solutions include government policies to limit pollution, renewable energy use, and individual efforts to reduce waste and resource consumption. Pollution includes air, water, noise, and soil contamination from sources like industry, vehicles, agriculture, and improper waste disposal. Mitigation involves filters, recycling, alternative fuels, and treating contaminated areas.

3. Global Warming
 Global Warming is an average increase in
the temperature of the atmosphere near
the Earth ’ s surface and in the
troposphere, which can contribute to
changes in global climate patterns.

4. Causes Of Global Warming
Man-made causes Natural causes

5. Causes
 Burning of fossil fuels (Coal/Crude oil)
 Power plants generate electricity
 Transportation fuels for transports (E.g. LPG,
kerosene, fuel oil)
 Industrial processes (E.g. manufacture of cement,
steel, aluminum)
 Other greenhouse gases emission
 Agriculture(use of fertilizers)
 Forestry(Deforestation)
 Other land uses (mining)
 Waste management

6. Besides carbon dioxide,
other gases such as methane,
chlorofluorocarbons,
nitrogen oxides and ozone
also contribute to the
greenhouse effect. Example :
Using natural gas to cook
CH4 + 2O2 CO2 + 2H2O

8. 5 Deadliest Effect Of Global
Warming
 The melting of the ice caps in the
polar region.
 The economic consequences.
 Increased probability and intensity
of drought and heat waves.
 Warmer waters and more hurricanes.
 Spread of diseases.

10. Measures on controlling the
problem
 Government
- Set some laws to limit the amount of pollutants
produced by factories.
-Develop the skills of using renewable fuels , e.g.
solar energy, wind energy.
-Encourage the factories to replace fossil fuels
by renewable fuels, which would not cause
environmental pollution.
-Carry out energy saving scheme -> reduce the
pollution produced by burning fossil fuels.
-Build more plants -> reduce the pollutants e.g.

11. Citizens
-Reduce the use of plastic bags -> as
burning plastic emit CH4.
-Recycle the resources, e.g. plastic
-Reduce the use of sprays -> as CFCs would
be emitted out
-Reduce the use of air-conditioner, which
will emit CFCs
-Use public transportation instead of
private cars -> reduce the pollutants

13. Air pollution

14. Air Pollution
 Air pollution is contamination of
the indoor or outdoor
environment by any chemical,
physical or biological agent that
modifies the natural
characteristics of the
atmosphere.

15. Sources Of Air Pollution
Household combustion
devices.
Motor vehicles.
Industrial facilities.
Forest fires

16. How to control air
pollution?
• Maintaining a healthy distance between
the industrial and residential areas.
• The chimneys should be constructed tall in
size so that the emissions must be released
higher up in the environment.
• The mining area should be planted with
trees.
• The coal fuel should be replaced with gas
fuel to control the air pollution.
• The automobiles must be designed with

17. How to control air
pollution?
•The wastes must be removed and recycled in
the industrial plants and refineries.
• Timely servicing of the car helps to keep it
in a good condition, and also minimizes fuel
exhaustion
• Using alternative energy sources like solar
energy, hydroelectric energy, and wind
energy.
• The wastes must be removed and recycled
in the industrial plants and refineries.

18. Air Pollution do have….
Health effects
Effects on cardiovascular health
Effects on breathing (asthma).
Links to cancer
Effects on children
Health effects in relatively
"clean" areas

19. Water Pollution….

20. Water Pollution…
 Water pollution is the contamination of
water bodies (e.g. lakes, rivers, oceans,
aquifers and groundwater).
 Water pollution occurs when pollutants
are discharged directly or indirectly into
water bodies without adequate
treatment to remove harmful
compounds.
 Water pollution affects plants and
organisms living in these bodies of

21. Water Pollution…
Domestic sewage.
Industrial wastewater.
Agricultural wastewater.
Construction site stormwater.
Urban runoff (stormwater).

22. Preventing Water Pollution…
 Conserve water by turning off the tap.
 Mind what you throw down your sink or
toilet.
 Don’t throw paints and oils in water
channels.
 Use environment friendly household
products, such as washing powder,
household cleaning agents etc.
 Take great care not to overuse pesticides
and fertilizers.

23. Treating Polluted Water...
 Suspended, solid particles and
inorganic material can be removed
by the use of filters.
 Use of biological filters and
processes can naturally degrade the
organic waste material.
 After above two steps chemical
additives are supplied to get rid of
any left-over impurities.

24. Treating Polluted water…

25. Noise Pollution

26. Noise Pollution
Noise pollution is displeasing
or excessive noise that may
disrupt the activity or
balance of human or animal
life.
Noise means disgust or
discomfort hearing from
environment.

27. Sources of Noise Pollution…
