This document discusses environmental health issues in the Philippines. It begins by defining environmental health and describing the natural and man-made environments. It then outlines the country's most pressing environmental problems, including uncontrolled deforestation, soil erosion, air and water pollution, coral reef degradation, and pollution of coastal areas. Specific issues like deforestation, soil erosion, air pollution, water pollution are then analyzed in more detail. The impacts of these environmental problems on human health, such as decreased access to food and water, respiratory illnesses, and other health effects, are also described.
2. Lesson Target:
A.Explain the concept of Environmental
Health.
B.Describe the Environmental
Problems in the Philippines
C.Analyze the impact of Environmental
problems on people's health.
7. The most pressing
environmental problems in
the Philippines:
1.Uncontrolled deforestation,
especially in watershed areas.
2.Soil Erosion
3.Air and Water Pollution in
Major Urban Centers
4.Coral Reef Degradation
5.Increasing pollution of coastal
mangrove swamps that are
important breeding grounds of
9. Deforestation
-Is the destruction of big areas of our
forests.
-clearance or clearing is the removal
of a forest or stand of trees where the
land is thereafter converted to a nonforest use.
10. Deforestation
One hundred years ago, the
Philippines had about 22,000,000
hectares of forest. In 2000 our forest
hadbeen trimmed down to 600,000
hectares (Imagine Echo Project,
2008). WHERE DID ALMOST 97%
OF OUR FORESTS GO?
11. MAjor reasons why we are losing
our forest:
•Agriculture
•Urbanization
•Illegal Logging
•Mining
•Forest Fires
12. Effects of Deforestation to our
health
The International Rice Research Institiute (IRRI)
in Los Banos, Laguna estimates that it takes
more than 4,000 liters of water to produce one
kilo of rice. Most of our freshwater comes from
watersheds in our forest. Deforestation has
resulted in the decrease of freshwater for our
farms. So loss of forest means loss of food. It
means also loss of other health products that
come from forests- clothings and medicines.
14. Soil Erosion
Happens when soil and rock are
moved from one place to another by
wind, water and gravity. It is brought
by natural and human activities.
Strong winds and heavy rains cause
soil erosion.
15. Human activities that cause Soil
Erosion:
•Deforestation
•Building of roads
•Agriculture
•Urbanization-- creation of towns and
cities
•Mining
16. Effects of Soil Erosion to our
health
Because most of our foods come from our
farmlands are, like our forests, fast
disappearing at the rate of more than
10,000,000 a year becAuse of soil erosion,
while more than 3.7 million people are
malnourished. Soil also loses its fertility
when the forest or farm is burned.
18. Air Pollution
The Philippines is spending
billions of pesos in income and
time loss and health care
expenses because of Air
Pollution,1.5 millions of
19. 2 Kinds of Air Pollution
1.Outdoor AIr Pollution
(OAP)
2.Indoor Air
Pollution(IAP)
21. Smog
Smog (smoke + fog) caused by
chemical reactions of
pollutants, mainly exhaust from
vehicles exhaust and factories.
It is a large scale outdoor
24. Indoor Air Pollution (IAP)
Common among poor families
because they use firewood,
dried animal manure and coal
in cooking and their kitchen is
poorly ventilated.
26. Effects of Indoor Air Pollution
(IAP)
Deaths due to indoor air
pollution are usually due to
chRonic obstructive pulmonary
diseases or COPD, pneumonia
and lung cancer.
27. Water Pollution
So many people are using water
for so many purposes--household
and industrial, such that much of
the waste water is no longer
treated or disposed properly.
They become pollutants in
