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 air quality, the 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 benefits ***** 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 for granted. We can forgive our forebears for ********** ignorance in develop*****g technologies with unforeseen consequences. Who could have known how human life would benefit by burning ***** for electricity or oil ***** au*****mobiles? However, the burning of these ***** has caused an epidemic of health and environmental problems and contributed to a general degradation of life on earth.

Air pollution is a bro*****d term that actually refers to a gamut of familiar environmental *****. *****se 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 ***** ***** 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 d*****asters. Acid rain is one ***** ***** fallouts of the ***** Revolution; before the proliferation ***** *****, the pH level of ***** tended ***** be slightly acidic, ***** ***** below ***** 5. ***** the Industrial Revolution, sulphuric acid ***** nitrogen gases that evaporate and combine with airborne water cause rain to ***** a pH level of 5 or lower. Cars are also the most major *****or to smog. Cities with huge transportation networks exhibit the highest levels of smog, especially if the 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 l*****e, but it also pollutes it due to the number ***** particulates that now l*****ter our air. Particulates are the large particles suspended in ***** air that not only cause smog ***** seep ********** the lungs of all animals. They include ***** from *****, diesel fuel, ***** dust.

Fossil fuel burning at power st*****ions ***** causes 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. Chlorofluoro*****s, which are commonly used in ***** conditioning, refrigeration, and solvents, also kindle ***** greenhouse effect, as does deforestation. Agriculture and w*****te disposal ***** also ***** culpr***** that b***** a*****out ***** warming as their *****-products emit greenhouse *****.

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