TheIndustrial Revolution and practical developments of the germ theoryplayed a significant role in increasing human population across theglobe. Industrial Revolution began in the mid-1700s and ran to the19th century leading to significant impact on human life andlifestyles(Hendricksonet al., 2015).According to Hendricksonet al.(2015), therealization of the impact of Industrial Revolution began in the 1800sas a result of human replacement labor by machines. The processes ledto increased food production, housing as well as medicine among othervaluable products. As a result, the society not only managed toproduce things faster but equally managed to produce qualityproducts. The evidence of Industrial Revolution’s impact onpopulations’ dynamics is best depicted in the worldwide humanpopulation growth. Before the Industrial Revolution began, the worldpopulation was estimated as below 350 million, most notably as aresult of the significant decline of human population in the late1300s impacted by the Black Plague where calamity left a populationof around 75 million people (Hendricksonet al., 2015).Since the Industrial Revolution, the number of people in the worldhas recorded significant growth to more than six billion in themodern world.

Centralto this increase in population is the germ theory disease based on arealization that microorganisms are the causative factors of manydiseases. According to Gradle(2009), sincethe proposal of the germ theory in the 16th century, its developmentoccurred during the Industrial Revolution helping to understand themanner most diseases progressed. The contribution by scientists likeLouis Pasteur to the germ theory proved significant in that he notonly described the manner organisms made people sick but equallypresented recommendations on the way to kill germs and protect humansfrom the germs. In Gradle (209), Pasteurization serves as a notableexample of the developments that enhanced in killing germs and thuspreventing people from illnesses that were the primary cause of deathbefore Industrial Revolution.
