Final answer:
Industrialization resulted in food surpluses due to advancements in agricultural efficiency, the mechanization of production, and improved crop varieties which augmented food output and enabled rural populations to engage in industrial work.
Step-by-step explanation:
Industrialization enabled the creation of food surpluses through advancements in agricultural efficiency. Achieving higher yields from farmlands, farmers no longer needed to focus solely on subsistence, allowing a portion of the population to migrate to cities and take up industrial employment.
The mechanization of agriculture led to increased productivity, which in turn facilitated the production of more food with less human labor. Innovations such as the use of fertilizer, the introduction of machinery like tractors, and improved crop varieties revolutionized farming practices.
These advancements also meshed with the economic principle of specialization and economies of scale, where remaining farms grew larger and more specialized, leading to even greater food output. Mass-produced agricultural machinery and improved transportation, like refrigerated railcars, made it possible to bring larger quantities of food to urban centers.
Additionally, the cultivation of new staple crops and scientific advances continued to boost agricultural yields. As a result of these factors, industrialization not only increased the availability of food but also contributed to a burgeoning consumer market for industrial products.
