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 ***** are many, and save for natural contributions to temporarily poor air quality, the bulk of ***** pollution problems ***** results ***** human technological advances. Since ***** Industrial Revolution, massive amounts of fossil fuels like coal and 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, ***** sp*****s of industrialization were taken for granted. We can *****give our forebears for their 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 ***** these fuels has caused an epidemic of health *****d environmental ***** and contributed to a general degradation of life 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 ***** depletion of the ozone *****. By far the biggest contributor to air pollution in general is ***** ***** ***** 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 ***** the fallouts of the Industrial Revolution; before the proliferation ***** *****, the pH level of ***** tended to be slightly acidic, but ***** *****low pH 5. Since the ***** Revolution, sulphuric acid and nitrogen gases that evaporate and combine with airborne water cause rain to ***** a pH level of 5 or lower. C*****rs are also the most major contribu*****r to smog. Cities with huge transportation networks exhibit ***** highest *****s of smog, especially if the city is geographically located in a bas***** that traps air. Los Angeles and Mexico City ***** 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 ***** air that not only ***** smog but seep ********** the lungs of all animals. They include ***** from *****, diesel fuel, and dust.

Fossil ***** burning at power st*****ions ***** ***** an excess of carbon dioxide to be emitted into the environment. This ***** only creates acid rain ***** also contributes to the greenhouse effect and global warming. Chlorofluoro*****s, which are comm***** used in air conditioning, refrigeration, and solvents, also kindle the greenhouse effect, as does deforestation. Agriculture and w*****te disposal ***** also major culprits that b***** a*****out ***** warming as their ********** 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
