with factories and heavy automobile trafficToday, we know that although these are the areas with the worst air pollution，the problem is literally worldwideOn several occasions over the past decade，a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile trafficIn fact， the very climate of the entire earth may be affected by air pollution Some scientists feel 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”-holding in heat reflected from the earth and raising the worlds average temperatureIf this view is correct and the worlds temperature is raised only a few degrees。much of the polar ice cap will melt and cities such as New Y0rk，Boston，Miami，and New Orleans will be under water Another view, less widely held，is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earths temperaturea result that would be equally disastrousA drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas At present we do not know for sure that either of these conditions will happen，though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likelyPerhaps，if we are very lucky, the two tendencies will offset each other and the worlds temperature will stay about
