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 air quality, ***** bulk of air pollution problems ***** 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 benefits of industry may indeed outweigh the detriments, but it is finally time ***** technology to solve *****s own problems. Until the past few decades, ***** sp*****s ***** industrialization were taken for granted. We can forgive our forebears for their ignorance in develop*****g technologies with unforeseen consequences. Who could have known how human life would benefit by burning coal for electricity or oil f***** au*****mobiles? However, the ***** o***** these fuels has caused an epidemic of health ********** environmental ***** and contributed to a gener*****l degradation ***** life on earth.

Air pollution is a bro*****d term that 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 layer. By far the biggest contribu*****r to air ***** in general is the burn*****g ***** 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 disasters. Acid rain is one of the fallouts of the ***** Revolution; before the proliferation ***** fac*****ries, the pH level of rain tended to be slightly **********, ***** rarely below pH 5. Since the Industrial Revolution, sulphuric acid ***** nitrogen gases that evaporate and combine with *****borne water cause rain to have a ***** level ***** 5 or lower. C*****rs are also the most major contributor 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 smog havens. The internal combustion engine ***** have revolutionized human life, but it also pollutes it due ***** the number ***** particulates that now litter 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 smoke, diesel fuel, ***** dust.

Fossil ***** burning at power stations also ***** an excess of carbon dioxide to be emitted ***** 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 *****, as does deforestation. Agriculture and w*****te disposal are also major culprits that b***** a*****out ***** warming as ***** by-products emit greenhouse gases.

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