Other planets have sunlight, but the Earth

is the only planet we know that has air

and water. Without air and water, the

Earth would be unable to sustain life.

A diverse community of plant and animal

life has thrived on this planet for millions

of years, sustained by the sun andsupported by the soil, water and air.

Air pollutants can cause a variety of health

problems - including breathing problems;

asthma; reduced lung function; lungdamage; bronchitis; cancer; and brain

and nervous system damage.

Air pollution can also irritate the eyes,nose and throat, and reduce resistance to

colds and other illnesses. Air pollution

can be especially harmful to the veryyoung, the very old, and those with

certain pre-existing medical conditions.


21/28

Air pollution also causes haze and smog

reduces visibility, dirties and damages

buildings and other landmarks, andharms trees, lakes and animals.

It is also responsible for thinning the

protective ozone layer in the upper

atmosphere that protects us from harmful

ultraviolet radiation from the sun, and may

be contributing to the phenomenon known

asglobal warming- the steady increase in

average temperature of the global climate.


22/28

Historical explanationHistorical explanation

With increasing urbanisation and

Industrialisation, humans started to releasemore wastes into the atmosphere than

nature could cope with.

Since then, more pollution has been added tothe air by industrial, commercial and

domestic sources. As these sources are

usually found in major cities, the gases thatare produced are usually concentrated in the

air around them.


23/28

The adverse effects of air pollutionwere graphically illustrated in London

in 1952 when, in just a few days, anestimated 4000 people died fromeffects of fine particle pollution.

It is when these concentrated gasesexceed safe limits that we have a

pollution problem. Nature can nolonger manage air pollution withoutour help.
