¡§Negative Impacts On Technologies¡
            
             Advanced technologies are potential threats to devastate the living environment.
            
             Although technologies has helped human beings to adapt an easier way of life,
            
             however, in the long term it might not be as beneficial as people realize. Many
            
             technologies have led to chronic devastations in the environment this includes
            
             automobiles, industrial power plants and medicines.
            
             The invention of automobiles have brought convenience to people, on the other
            
             hand, it also causes air pollution. Driving is probably the most polluting act an
            
             average citizens commits. Pathogens in car exhaust like carbon monoxide, nitrogen
            
             dioxide, sulphur dioxide, benzene and polycyclic hydrocarbons are toxic to human
            
             body organs. These substances have been shown to produce harmful effects on the
            
             blood, bonemarrow, spleen and lymphnodes, any of these pollutants can cause anemia,
            
             cardiovascular disease, hypertension and the possibilities of developing several types
            
             of cancers. Furthermore, combustion car engines contribute to carbon dioxide
            
             accumulation in the atmosphere is responsible for climate changes. Carbon dioxide is
            
             the main culprit of greenhouse effect. Meteorological reading taken in the stratosphere
            
             over the Arctic show that in six of the past 10 winters, ozone has thinned to half its
            
             concentration. Ozone protects the Earth from the Sun¡s ultraviolet radiations and
            
             doctors are concerned that if it is eroded more people will suffer from skin cancer.
            
             Moreover, the greenhouse effects is also a main reason responsible for global
            
             temperature to increase slightly every year. Report indicates that during the past 20
            
             years, average temperature has increased 0.5 degrees and in the following century the
            
             temperature will increase 2 to 5 degrees worldwide. Scientists are concerned about
            
             that consequently a...
