From the information given in the above column chart,we can see a striking contrast in mobile phone
subscriptions between developing and developed countries from 2000 to 2008.During this period,there
has been a dramatic increase from 0.4 to 4 billion mobile phone subscriptions in developing
countries,while that of developed countries remianed steady under 1 billion.At least two fundamental
factors could contribute to this phenomenon.On the one hand,with the rapid increase in economy
happening in the developing countries,the telecommunication industry in those countries got a great
bound to meet the demand of globalization.As a result,the user of mobile phone which can narrow the
distance between people and link the whole world together rose at an incredible speed.On the other
hand,the extremely advanced civilization of developed countries means less potential in many aspects
including in the area of private telecommunication tools.And their demand for further enlargement of
such tools tends to saturation.In conclusion,while mobile phone subscriptions,if used carelessly or
without restraint,could prove to be a double edged sword,the facct remains that it is already
extremely prevalent in both developing and developed countries and even today,continues to rise in
popularity.If people could imbue themselves with intelligence,prudence,and discretion,I am sure that
most of them will be able to sidestep the potential drawbacks of mobile phones as well as take
advantage of all the merits.
