3. Deforestation
The act of clearing of the
forest by cutting down trees
for its valuable timber, and
for building of roads, houses,
industrial estate and so on.

5. Soil Erosion / Landslide

6. Water Pollution
The sources of water pollution:
• Effluent from industrial and domestic
sources.
• Agricultural waste.
• Discharge of untreated sewage.
• Oil spills in the sea.

7. Water

13. Air Pollution

16. API
A system adopted by Malaysia
Government to indicate the level
of air pollution based on its
health impact
API
(Air Pollution Index)
Descriptor
0 – 50 Good
51 – 100 Moderate
101 – 200 Unhealthy
201 – 300 Very unhealthy
> 300 Hazardous

17. ACID rain
• Sulphur dioxide (SO2)
• Oxides of nitrogen (NO, NO2)
Caused by:
• Combine with water vapour in the
atmosphere to form sulphuric acid and
nitric acid respectively.
• They fall back on earth as acid rain.

20. Noise Pollution
• When the noise of the surroundings
become excessive and disturbs the
comfort of living.
• Sources:
 aeroplane, trains, construction works
wheels and factory machines,
vehicles along the roads.

• mainly due to the increaLLsiaangyy leeevrrels of chlorofluorocarbons
(CFC) in the atmosphere
CFC uses as coolants in air conditionals and
refrigerators, as propellants in aerosol cans
and as foaming agents in making Styrofoam
packaging

25. Proper management of development activities and the ecosystem
• Implementation of laws
• Use of technology
• Education on the management of resources
• Preservation and conservation of soil, water,
forests and mangrove swamps.
• Practice of biological control
• Use of renewable energy
• Efficient use of energy
