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.

Soil Erosion / Landslide

Water Pollution

The sources of water pollution:

• Effluent from industrial and domestic sources.

• Agricultural waste.

• Discharge of untreated sewage.

• Oil spills in the sea.

Water Pollution

Air Pollution

APIA 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

ACID rain

• Sulphur dioxide (SO2)

• Oxides of nitrogen (NO, NO2)

• Combine with water vapour in the atmosphere to form sulphuric acid and nitric acid respectively.

• They fall back on earth as acid rain.

Caused by:

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.

The Thinning of The Ozone The Thinning of The Ozone LayerLayer• mainly due to the increasing levels of chlorofluorocarbons

(CFC) in the atmosphereCFC uses as coolants in air conditionals and refrigerators, as propellants in aerosol cans and as foaming agents in making Styrofoam packaging

Effects of Ozone Effects of Ozone DepletionDepletion

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
