2. Introduction
The environment faces a lot of issues
and problems in the modern era.
These concerns greatly affect the living
conditions of the community.
This lesson will provide you an
understanding of the nature of these
environmental issues and their impact
on the health of the community.
4. Pollution refers to the accumulated contamination of
different settings in the environment: atmosphere,
water, and land.
There are different types of pollution.
Air Pollution
Water Pollution
Noise Pollution
Land Pollution
Pollution
5. Air Pollution
Air pollution refers to the
contamination of air in the environment.
It causes harm to a person’s health.
It may cause suffocation or difficulty in
breathing.
The following are sources of air
pollution.
Burning of fossil fuels
Particulates such as dirt and dust
Smoke from cars and factories
Smoke from tobacco
6. Water Pollution
Water pollution refers to the contamination of
water in the environment.
When polluted water makes contact with the
skin or enters the body, it may cause
diseases.
Contaminants in water come from different
sources including the following.
Human wastes and garbage thrown into
bodies of water
Harmful chemical wastes from industries
Washing down of chemical fertilizer from
farms to rivers
Oil spillage from watercraft
7. Noise Pollution
Noise pollution refers to excessive noise in the
environment that may cause hearing
impairments, stress, irritation, fatigue, and
tension.
Noise pollution also affects the emotional
environment of the community because it may
affect people’s moods and emotions.
Excessive noise in the environment may come
from different sources.
Noise from vehicles
Noise from electrical equipment
Noise from people
Noise from construction and other industries
8. Land Pollution
Land pollution refers to the exposed
wastes on land.
These wastes may cause diseases
when inhaled or ingested.
It may also destroy the ecosystem in
the community once the soil is
contaminated.
9. Mining is a procedure done to acquire minerals from land.
These minerals are used for different purposes.
Mining is considered illegal when:
There is no permit secured from government
authorities.
The method uses equipment and procedures that will
damage the environment and harm people.
Illegal Mining
10. Illegal mining is harmful to the environment and people.
Below are examples of effects of illegal mining.
Illegal mining occurs in mountainous areas that are rich
in minerals. These minerals are acquired by first
clearing the mountains by cutting trees, and then
breaking rocks and digging. All these can cause
erosion and landslides.
Illegal mining uses harmful chemicals and explosives
to dig minerals. These substances may contaminate
the soil and kill the plants and animals that live there.
Chemicals from illegal mining may contaminate water
sources.
11. Deforestation is defined as the clearing of plants and trees
in the forests.
It is considered a destruction of natural resources.
This practice is done for several reasons.
People clear forests for mining purposes.
Deforestation is used so that land may be utilized for
commercial or residential purposes.
People cut down trees to produce wood materials used to
make different products.
Deforestation
12. Deforestation has negative effects on the
environment and people.
Animals lose shelter without trees. Plants and
trees are also sources of food for animals. Without
plants, animals will eventually perish as well.
Plants and trees produce fresh air. If forests are
cleared, air quality becomes less healthy.
Plants and trees serve as flood controllers. They
absorb rainwater to prevent flooding. Deforestation
can cause flash floods.
13. Soil erosion is defined as the transfer of soil from
one place to another.
It may be caused by different factors.
Soil is blown by strong winds.
Soil is washed away by water.
Soil is transferred to another place by humans.
Soil Erosion
14. In general, soil erosion naturally occurs.
However, when there is large amount of soil displaced,
it may pose a threat to the environment and the people.
Erosion affects the quality of soil. Plants may not
grow healthy if there is soil erosion.
Soil erosion may clog waterways.
Soil erosion may increase the possibility of flooding.
15. Cyanide fishing is a fishing method that uses
a toxic substance called cyanide to kill and
harvest aquatic animals.
This causes an imbalance in the ecosystem
and may lead to widespread animal death.
Cyanide Fishing
16. Coral Reed Degredation
Coral reef degradation refers to the gradual
destruction of coral reefs caused by natural or
man-made events.
Damage to coral reefs may be caused by
earthquakes, hurricanes, or volcanic eruptions.
Water pollution, fishing chemicals, and explosives
cause damage to coral reefs.
17. Oil Spill
An oil spill is the release of petroleum in the water.
It is caused by human activities.
Oil spill is a form of water pollution.
Oil spills are harmful to the aquatic animals and
people.
This is what causes the death of animals and
plants living in water.
18. Pesticide Drift
Pesticide is a chemical substance used on plants
to kill insects that feed on them.
It may be applied by a person, a machine, or even
a vehicle.
Pesticide is a toxic substance and may cause
disease or death when ingested by humans and
animals.
19. Global Warming
Gases like carbon dioxide that are present in the
atmosphere trap heat near the earth’s surface.
Heat and light from the sun enters but is prevented
from escaping because of these gases.
This phenomenon is called the greenhouse effect.
Carbon Dioxide is considered as a greenhouse gas.
20. Below are other examples of greenhouse gases.
methane gas from vehicle emissions
chlorofluorocarbons (CFCs) from aerosol sprays
When greenhouse effect happens, the temperature of
the Earth increases.
This results to a phenomenon called global warming.
Global warming causes a lot of impact to the
environment and people.
21. Global warming melts the ice in polar regions.
This causes sea levels to rise.
Global warming causes climate change.
Climate change is the change in weather patterns
across the world.
This might cause discomfort, stress, or even
diseases.

23. Introduction
The environment is where people live.
It influences the attainment of quality life
because it is the source of basic needs.
If the environment is not protected, it may
pose harm and threat to people's health.
This lesson will provide an understanding
of the roles and responsibilities of people
in the community in preserving a healthy
environment.
25. Protecting the environment starts with
personal responsibility and social
consciousness.
Personal environmental
responsibility refers to the awareness
of one’s roles in keeping a healthy
community and environment.
Social consciousness refers to the
awareness of what is currently
happening around you and being able to
critically reflect on how to respond to
them.
26. Practice proper waste
management.
Do not contribute to the pollution in
the environment.
Minimize wastes.
If they cannot be prevented, ensure
that wastes are properly disposed or
managed using the 5Rs strategy.
27. Do not perform
activities that may
damage or destroy the
environment.
When you travel, leave as little trace
of yourself as possible.

graffiti on rocks.
28. Keep things in their
natural environment.
Never take things away from nature.
This may disrupt the ecological
balance in the environment.
Do not pick flowers or plants.
Do not take animals or other objects
from the environment.
29. If going on a nature trip
or visit, stay on trails.
Trails are man-made paths assigned
to protect people from harm.
These paths are also made so that
the environment remains undisturbed
and protected from possible harmful
activities of people.
31. Initiate actions that
promote the protection
of the environment.
Start with consistently practicing
healthy ways such as planting trees
or growing plants, regularly cleaning
your area, and others.
32. Encourage other
people to take part in
the efforts to protect
the environment.
