What was one of the major reasons for the decrease in the need for agricultural workers?

One major reason for the decrease in the need for agricultural workers is the advancement of agricultural technology, such as mechanization and automation. These innovations allow fewer workers to produce more food efficiently, reducing the demand for manual labor. Additionally, the shift toward industrialized and commercial farming practices has led to larger operations that rely on machines rather than human labor. This combination of factors has significantly transformed the agricultural workforce landscape.
