The ring of haze surrounding modern cities looms ominously and the hole in the ozone layer grows, but people rarely underst***** that air pollution is within our control. The causes of air pollution are many, and save for natural contributions to temporarily poor air quality, ***** bulk of air pollution problems are results of human technological advances. Since the Industrial Revolution, massive amounts ***** fossil fuels like coal and oil have been and continue to be consumed. The *****nefits of industry may indeed outweigh the detriments, but it is finally time ***** technology to solve ********** own problems. Until the past few decades, the sp*****s ***** industrialization were taken for granted. We can *****give our forebears for ********** ignorance in developing technologies with unforeseen consequences. Who could have known how human life would benefit by burning ***** for electricity or oil ***** automobiles? However, the ***** of these fuels has caused an epidemic of health and environmental ***** ***** contributed to a general degradation ***** life on earth.

Air ***** is a bro*****d term that actually refers to a gamut of familiar environmental problems. These problems include acid rain, domestically produced smoke, smog, the greenhouse effect, particulates, radionuclides, and the depletion of ***** ozone *****. By far the biggest contribut***** to air pollution in general is ***** burning of fossil fuels, by both automobiles and factories. Power stations and road vehicles are boons to civilization but ***** also at the root of environmental and health d*****asters. Acid rain is one of ***** fallouts of the ***** Revolution; before the pro*****ration of factories, the pH level of ***** tended to be slightly *****ic, but ***** *****low pH 5. Since the Industrial Revolution, sulphuric acid and nitrogen gases that evaporate ***** combine with ********** water cause rain to have a pH level of 5 or lower. Cars are also the most major *****or ***** smog. Cities with huge transportation networks exhibit the highest levels of smog, especially if ***** city is geographically located in a bas***** that traps air. Los Angeles and Mexico City are perfect examples of smog havens. The internal combustion engine may have revolutionized human life, but it also pollutes it due to the number of particulates that now l*****ter our air. Particulates are the large particles suspended in the air that not only cause smog ***** seep into the lungs of all animals. They include ***** from smoke, diesel fuel, and dust.

Fossil ***** ***** at power ***** also ********** an excess of carbon dioxide to be emitted ***** the environment. This ***** only creates acid rain but also contributes ***** the greenhouse ***** and global warming. Chlorofluoro*****s, which are commonly used in air conditioning, refrigeration, and solvents, also kindle the greenhouse effect, as does deforestation. Agriculture and w*****te disposal ***** also ***** culprits that b***** a*****out global warming as their ********** emit greenhouse *****.

Radionuclides come from processes like X-rays that emit ionizing radiation, causing severe detrimental effects on ***** life forms. Besides governmental regulati*****, steps must
