Refrigeration is a process in which work is done to move heat from one location to another. Refrigeration has had a large impact on industry, agriculture and lifestyle of people. The increase in food sources has led to a larger concentration of agricultural sales coming from a smaller percentage of existing farms. Farms today have a much larger output per person in comparison to the late 1800s. This has resulted in new food sources available to entire populations, which has had a large impact on the nutrition of society.
