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 contri*****ions 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 *****s 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 ***** automobiles? However, the ***** ***** these ***** has caused an epidemic of health *****d environmental ***** and contributed to a gener*****l degradation ***** life on earth.

Air pollution is a broad term ***** 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 the ozone layer. By far the biggest contribut***** ***** air pollution in general is ***** 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 ***** the fallouts of the ***** Revolution; before the pro*****ration ***** factories, the pH level of rain tended to be slightly *****ic, but rarely below pH 5. Since the Industrial Revolution, sulphuric acid ***** nitrogen gases that evaporate and combine with airborne water cause rain to have a pH level ***** 5 or lower. C*****rs are ***** the most major contribu*****r to smog. Cities with huge transportation networks exhibit ***** highest levels of smog, especially if the city is geographically located in a basin that traps air. Los Angeles and Mexico City ***** perfect examples of ***** havens. The internal combustion engine may have revolutionized human l*****e, but it also pollutes it due to the number of particulates that now l*****ter our air. Particulates are the large particles suspended in ***** air that not only cause smog ***** seep into the lungs of all animals. They include ***** from *****, diesel fuel, ***** dust.

Fossil ***** burning at power ***** ***** ********** an excess of carbon dioxide to be emitted into the environment. This not only cre*****es acid rain but also contri*****es to the greenhouse ***** and global warming. Chlorofluorocarbons, which are comm***** used in ***** conditioning, refrigeration, and solvents, also kindle the greenhouse effect, as does deforestation. Agriculture and waste disposal ***** also ***** culprits that bring about ***** warming as their by-products 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
