¡§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.

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 as the temperature increases every year the sea level will increases .
