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 pollution are many, and save for natural contri*****ions to temporarily poor ***** 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 of industry may indeed outweigh the detriments, but it is finally time for technology to solve *****s own problems. Until the past few decades, ***** spoils of industrialization were taken for granted. We can ********** 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 for au*****mobiles?

Agriculture and waste disposal are also ***** culprits that b***** a*****out global warming as their *****-products emit greenhouse *****.
