The first thing people see, in the morning, when they walk outside is the sky or the colored sun. Not only are beautiful sights such as this hidden behind the pollution this world causes everyday, but an increase in diseases, infections and death occurs. Factory and business owners have the ability to prevent air pollution.
Air pollution is the presence in the atmosphere of harmful gases, liquids, or solids.
Smog has been a problem in coal-burning areas for several centuries. Smog finally decreased when coal combustion was replaced by oil and gas combustion. Air pollution is caused by a number of different types of pollutants. The first type, particulate matter, consists of solid and liquid aerosols suspended in the atmosphere. These arise from the burning of coal and from industrial processes.
