The document discusses several local environmental issues including deforestation, wildlife depletion, water pollution, air pollution, and coastal destruction. It notes that deforestation is caused by kaingin farming, illegal logging, and land conversion, and that it leads to soil erosion, floods, and loss of wildlife. Water pollution problems mentioned include eutrophication from organic waste, toxic waste, and fertilizer runoff. Air pollution issues discussed are the greenhouse effect and global warming due to carbon dioxide and other gas buildup. A quiz is also provided to test understanding of these topics.

1. Local and Environmental
Issues/Problems
Affecting community

2. I. DEFORESTATION - Rapid rate at
which trees are cut down.
Major Causes
 Kaingin Farming
 Illegal logging
 Conversion of
agricultural lands to
housing projects
 Forest fires
 Typhoons
Effects
 Soil erosion
 Floods
 Decrease in wildlife
resources that will
eventually lead to
extinction

3. II. WILDLIFE DEPLETION –
disappearance of wildlife species
As a human population gets
bigger, huge space is needed
for shelter, for growing crops
and for industries.
Cause: Deforestation

4. III. Water Pollution
EUTROPHICATION
major problem in lakes, rivers
and ponds
Happens when the concentration of
organic nutrients that comes from
domestic garbage and thrown in a
bodies of water, increases rapidly

5. When does “FISH KILL” happen?
It usually happens when
there is an increase in
concentration of organic
nutrients in bodies of
water.

6. WATER POLLUTANTS
Toxic waste
Untreated sewage
 Fertilizers run-offs from farm lands
Heavy metals, such as:
 Lead
 Mercury
 cadium

10. PCB or POLYCHLORINATED
BIPHENYL
Are toxic wastes
produced in the making
of paints, inks and
electrical insulators

12. BIOLOGICAL MAGNIFICATION
Is the build-up of pollutants in
organism at higher trophic level in
a food chain.
Through this PCB or
polychlorinated biphenyl becomes
concentrated in the body tissues
of water organism

13. IV. AIR POLLUTION

14. GREENHOUSE EFFECT
The trapping of heat
by gases in the
earth’s atmosphere
 ..VideosENVIRONMENTAL SCIENCEGlobal Warming , Green
House Effect , Ozone Layer Video for Kids.mp4

15. GLOBAL WARMING
An increase in the earth’s
temperature from the
rapid buildup of carbon
dioxide and other gases

16. V. Destruction of Coastal Resources
Activities that destroy coastal areas:
Deforestation, agricultural activities, and
mining activities
Dynamite fishing and muro-ami
Coastal areas conversion to beach
resorts, residential areas
Overharvesting

17. VI. Acid Precipitation
Known as ACID RAIN
Pollutants: Sulfur, nitrogen
oxides – make rainwater even
more acidic (with 5.6 pH or
lower)

18. SUSTAINABLE DEVELOPMENT
Means that a society
should live under the
carrying capacity of the
environment
