Farming is important because it provides food and jobs in a society. Industrial farming provides a large amount of food for a relatively low cost. Family farming improves the local land and reduces the family's dependency on commercially grown food and grocery stores.
Farming and agriculture is essential to the success of society as a whole. Without farming, everyone would be forced to hunt and gather food, and it is not possible for the world's population to survive off such an eating style. Industrial farming techniques and genetically modified crops allow farmers to produce a much greater amount of food than in the past, even when using the same amount of land, which keeps food on tables. Industrial farming also employs many people, including hourly workers, seasonal workers and scientific researchers who seek to improve farming techniques.
Family farming is important on a much smaller scale. Family farming provides local foods to the community when there is excess produced, and it provides for much of the family's food intake otherwise. This allows the family to save money and reduces dependence on industrial farming. Small family farms also keep the land in good shape through regular tilling and care, improving the overall health of the local ecosystem.
