LECTURE 1 INTRODUCTION

Firman Allah “Berlakulah kerosakan (bencana) di

daratan dan di lautan oleh kerana usaha manusia sendiri, sehingga Allah menimpakan pada mereka sebahagian azab daripada perbuatan mereka itu, agar mereka kembali ke jalan yang benar (bertaubat).”

…( Surah Ar Rum ayat 41)

LECTURE 1 INTRODUCTION

Allah says “Mischief has appeared on land and sea

because of (the need) that the hands of men have earned that (Allah) may give them a taste of some of their deeds: in order that they may turn back (from Evil)”

…( Surah Al Room verse 41)

HOW BEAUTIFUL IS OUR EARTH

“EARTH IS OUR FRIEND NOT ENEMY”

THE DISTRUCTION IS SO DIVASTATING

GOD’S RECIPROCATION IS REGARDLESS WHO & WHERE

SUSTAINABLE DEVELOPMENT

“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Brundtland Commission report of 1987

04/08/23 7

WHY SUSTAINABLE DEVELOPMENT?

Urban Population expected to grow by between40% to 50% by 2030 from 70% to 80% of Total Population. The way we plan our Cities will be a Key component of a sustainable future24% of Urban Home Energy consumption is from the use of the Car to & from work31% of Urban Home Energy consumption is from the use of the Car for after workMalaysia will become a Net Importer of Energy by 2010. How we design our homes will reflect how much energy they require to run.

STATUS OF THE MAIN NATIONAL ENVIRONMENTAL COMPONENTS (WATER,

AIR, FOREST & BEACHES)

WATER (MOST IMPORTANT – MOST POLLUTED)USES DOMESTIC USE (DRINKING, WASHING,

COOKING, BATHING) INDUSTRY & PUBLIC USE (IRRIGATION,

FISHERY, PROCESSING, ELECTRIC)

SIGN OF POLLUTIONS

FREQUENT OCCURRENCE OF FLASH FLOODS IN MAJOR CITIES (KL ETC) – UNCONTROLLED DEVELOPMENT PROCESS : EXAMPLES; CUTTING OF HILL LAND IN KLANG VELLY

AREA & CAMERON HLD. – EROSION – SEDIMENTATION OF MUD IN KLANG RIVER.

WASTE POLLUTION (WASTE DISPOSAL FROM PALM OIL & RUBBER MILLS, EFFLUENT DISCHARGED FROM ANIMAL FARMS AND FACTORIES) 1976 – 42 RIVERS ARE CATEGORISED AS

POLLUTED 16 ARE HIGHLY PULLUTED (SG.PINANG)

04/08/23 45

i) INDUSTRIAL WASTE WATER (CLOROFORM, BIFENIL, PLUMBUM ETC.)

STEEL INDUSTRIES – 29% TEXTILE INDUSTRIES – 15 % GAS INDUSTRIES – 14% ASBESTOST FACTORIES – 9%

ii) HUMAN & ANIMAL WASTE WATER (EFFLUENT & SANITATION WATER)

DISCHARGED DIRECTLY INTO WATER SOURCES INCOMPLETE PROCESSING OVERFLOW INTO FRESH WATER SOURCES

DURING HEAVY RAIN LEAKED PIPES AND CROSSINGS

04/08/23 46

CONTROL OF WATER QUALITY (AKTA KUALITI ALAM SEKITAR 1974 PINDAAN 1985)

WATER IS BEING CONTROLLED BY ITS CEMICAL, BIOLOGICAL, PHYSICAL CHARACTERISTIC & ITS CONTENT. (REVERSE OSMOSIS, ELECTRO-DYLISIS, CARBON ABSORPTION & CHEMICAL REACTION)WASTE DISPOSAL MUST BE FILTERED FIRST BEFORE DISPOSED INTO RIVERS OR WATER COURSES.CATCHMENT AREA & ITS SURROUNDING MUST BE PROTECTED FROM BEING CLEARED.ALL DOMESTIC WASTE WATER, FACTORIES & ANIMAL FARMS – CHANNELED INTO ANY TREATMENT PLANTS, CLEANED - DISPOSED.

PROBLEMS TO BEACH & COAST

“COASTAL ECOSYSTEM ARE BEING DISTURBED & DISTROYED”COAST OF THE PENINSULAR 2,300KM IN LENGTH.30% SETTLEMENTS CONCENTARTED ALONG THE COAST.CAUSES OF DISTURBANCES: MINING FISHING AQUACULTURE INDUSTRIES PETROLEUM SHIPPING AGRICULTURE HOUSING

04/08/23 48

DISTRUCTIONCORAL REEFS: MOST OF THE ISLANDS ALONG THE EAST

COAST HAVE BEAUTIFUL CORAL REEFS. FUNCTION – WAVE BREAKER, FISHING (10 –

25%) DAMAGED BY:

SUSPENSION (CLOUDINESS) FOREST CLEARING. (CLOUDINESS LIMITS SOLAR RADIATION FOR THE CORAL MICRO ORGANIASM TO GROW).

EXAMPLE PULAU REDANG

04/08/23 49

MANGROVETHE STATUS OF MANGROVE FOREST: 113,384 HECTRE, ALONG SELANGOR &

JOHOR COASTLINES (87%). DAMAGED BY:

COASTAL FISHING ACTIVITIES WASTE DISPOSAL. CHANGE OF LAND USE. UNCONTROLLED LOGGING.

EXAMPLES: KUANTAN, CENDERING

RECLAIMATION OF MANGROVE SWAMP

EFFECT OF AIR POLLUTON: DESEASE OUTBREAKS DESTRUCTION, DEFECT TO HUMAN &

PLANTS DISTURBANCES IN ENJOYING LIFE DISTURBANCES IN VIEWING DESTRUCTION OF ENVIRONMENTAL

2. ORGANIC & INORGANIC GASSES : CARBON OXIDE

CO MORE HARMFUL – ODOURLESS, COLOURLESS, LONG LIFE SPAN.

EFFECT CHANGES PHYSIOLOGICAL SYSTEM POISONOUS

& SUFFOCATION.

SULPHUR OXSIDE MOST QUANTITY & DANGEROUS SORE THROAT. PRODUCT OF BURNING COAL & ACID FACTORY.

EFFECT DELAY IN DRYING OF PAINTWORK, BLEACHING OF

COLOUR.
