This document defines and discusses different types of pollution including air, water, and land pollution. It outlines key causes and effects of each type of pollution and provides some solutions to prevent further pollution. The international response section notes that many countries have enacted legislation to regulate pollution and mitigate its effects, while international treaties through the UN address cross-border pollution issues, though implementing effective global measures remains a major challenge.

3. Pollution
 Pollution is the introduction of contaminants into a
natural environment that causes instability,
disorder, harm or discomfort to the ecosystem .
 Pollution can take the form of chemical
substances or energy such as noise, heat or light.

5. Air pollution : Definition
Air pollution is the
introduction of
chemicals, particulate
matter, or biological
materials that cause
harm or discomfort to
humans or other living
organisms, or damages
the natural environment
into the atmosphere.

6. - Industries.
-Automobiles and Domestic fuels
-Fire
-High Proportion of undesirable
gases, such as sulphur dioxide and
carbon monoxide
Air pollution : Causes

7.  Human health
 Animals
 Plants
 The atmosphere as a whole
 Acid rain
Air pollution : Effects

8. How to prevent air pollution ?
 Carpool
 Walk or ride a bicycle
 Connect your outdoor
lights to a timer or use
solar lighting.
 Wash clothes with warm
or cold water instead of
hot.
 Plant trees etc…….

10. Water pollution is the
contamination of water bodies
(e.g. lakes, rivers, oceans,
aquifers and groundwater).
Water pollution occurs when
pollutants are directly or
indirectly discharged into
water bodies without adequate
treatment to remove harmful
compounds
Water pollution : Definition

11.  Marine Dumping
 Industrial Waste
 Sewage, mainly from
households
 Nuclear waste
 Oil pollution
 Underground storage
leaks
Water pollution : Causes

12.  Diseases like Cholera
 Malaria
 Typhoid (spread during
the rainy season )
 Aquatic life gets
destroyed
Water pollution : Effects

13.  Turn off running water
 Fertilize correctly
 Organize or participate
in a clean up
 Join a special society
devoted to the
prevention of water
pollution
Water pollution : Solutions

15. LAND POLLUTION
Land pollution is the
destruction of Earth's land
surfaces through misuse of
land resources by human
activities. Polluted land has
deposits of liquid and solid
waste such as rubbish,
garbage, paper, glass and
plastic objects.

16.  Accidental Spills
 Industrial Accidents
 Landfill and illegal dumping
 Agricultural practices
 Mining and other industries
 Oil and fuel dumping
 Buried wastes
 Drainage of contaminated
surface water into the soil
 Electronic waste
Land pollution : Causes

17. Land pollution : Effects
Contaminated lands and environments can:
 Cause problems in the human respiratory system.
 Cause problems on the skin.
 Cause various kinds of cancers.
The toxic materials that pollute the soil can get into the
human body directly by:
 into contact with the skin.
 washed into water sources like reservoirs and rivers.
 Eating fruits and vegetables that have been grown in
polluted soil.
 Breathing in polluted dust or particles.

18. How to prevent land pollution
 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.

20. International Response
 To protect the environment from the adverse
effects of pollution, many nations worldwide
have enacted legislation to regulate various
types of pollution as well as to mitigate the
adverse effects of pollution.
 Since pollution crosses political boundaries
international treaties have been made
through the United Nations and its agencies
to address international pollution issues.
 Today, there are more than 500 international
treaties and other agreements that relate to
the environment.

21. Challenge
At the global level, it remains a daunting challenge
to design and implement effective measures that
can motivate citizens, companies, institutions,
networks and governments to cooperate and deliver
ambitious policies and action!

22. Conclusion
I am the earth.
You are the earth.
The Earth is dying.
You and I are murderers
Let us stop killing the
Earth
