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 contributions to temporarily poor ***** quality, ***** bulk of air pollution problems are results ***** human technological advances. Since the Industrial Revolution, massive amounts of fossil fuels like coal ***** oil have been and continue to be consumed. The *****nefits ***** industry may indeed outweigh the detriments, but it is finally time for technology to solve its own problems. Until the past few decades, the sp*****s of industrialization were taken ***** 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 ***** for electricity or oil f***** automobiles? However, the burning ***** these ***** has caused an epidemic o***** health ********** environmental problems and contributed to a gener*****l degradation of ***** on earth.

Air ***** is a broad term that actually refers to a gamut of familiar environmental *****. These problems include acid rain, domestically produced smoke, smog, the greenhouse effect, particulates, radionuclides, and the depletion of the ozone *****. By far the biggest contribu*****r to air pollution in general is the burn*****g ***** 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 ***** ***** fallouts of the Industrial Revolution; before the proliferation of *****, the pH level of ***** tended to be slightly acidic, ***** rarely below pH 5. Since the Industrial Revolution, sulphuric acid and nitrogen gases that evaporate and combine with airborne water cause rain to ***** a ***** level ***** 5 or lower. C*****rs are also the most major contributor to smog. Cities with huge transportation networks exhibit the highest *****s of smog, especially if ***** city is geographically located in a basin that traps air. Los Angeles and Mexico City ***** perfect examples of smog havens. The internal combustion engine may have revolutionized human l*****e, but it also pollutes it due to the number of particulates that now litter our air. Particulates are the large particles suspended in ***** air that not only cause smog ***** seep ********** the lungs of all animals. They include particles from smoke, diesel fuel, and dust.

Fossil ***** burning at power stations ***** ***** an excess of carbon dioxide to be emitted into the environment. This ***** only creates acid rain but also contributes to ***** greenhouse effect and global warming. Chlorofluoro*****s, which are commonly used in ***** conditioning, refrigeration, and solvents, also kindle the greenhouse effect, as does deforestation. Agriculture and w*****te disposal ***** also ***** culprits that bring about global warming as their by-products emit greenhouse g*****es.

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