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

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

Fossil ***** ***** at power st*****ions also ***** an excess of carbon dioxide to be emitted into the environment. This ***** only creates acid rain but also contri*****es to the greenhouse ***** and global warming. Chlorofluorocarbons, which are commonly used in ***** conditioning, refrigeration, and solvents, also kindle the greenhouse effect, as does deforestation. Agriculture and waste disposal are also major culpr***** that bring about global warming as their ********** emit greenhouse g*****es.

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