  This paper focuses on the potential impact of air pollution.Is it worth the progress of human civilization at the cost of air pollution?

  text

  People used to think that air pollution only affected areas with factories and heavy car traffic around big cities.At present,we realize that although these are the areas with the worst air pollution,the problem is literally worldwide.On several occasions over the past decade,a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic.

  In fact,the very climate of the entire earth may be infected by air pollution.Some scientists,consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil)is creating a"greenhouse effect"-conserving heat reflected from the earth and raising the world′s average temperature.If this view is correct and the world′s temperature is raised only a few degrees,much of the polar ice cap will melt and cities such as New York,Boston,Miami,and New Orleans will be in water.

  Another view,less widely held,is that increasing particular matter in the atmosphere is bloc-king sunlight and lowering the earth′s temperature--a result that would be equally disastrous.A drop of just a few degrees could create something close to a new ice age,and would make agriculture difficult or impossible in many of our top farming areas.Today we do not know for sure that either of these conditions will happen(though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible).Perhaps,if we are lucky enough,the two tendencies will offset each other and the world′s temperature will stay about the same as it is now.

  Driven by economic profit,people neglect the damage on our environment caused by the"advanced civilization".Maybe the air pollution is the price the human beings have to pay for their develop-ment.But is it really worthwhile?
