Smokestacks were first used during
Industrial Revolution between the 18th and 19th centuries and were known to foul the airs in most larger cities but were most noted in large industrial centers like Manchester England or Pittsburgh Pennsylvania. During the dramatic growth and evolution of systems used to produce electricity coal burning central electric stations that relied on
direct current were found throughout cities that released noxious fumes and
soot into the city air. Taller smokestacks helped to reduce this
environmental issue. ==External links==
