City people sometimes move to a farming community and then are somewhat shocked that the beautiful fields are actually not just for looking at and painting. A farmer's fields are a sort of factory. The fields produce stuff. They take inputs of raw materials, such as seeds, fertilizer, water, pesticides, and so forth. With these inputs, they produce food. Some farms are organic, and they use non-chemical fertilizer and more "natural" methods of pest control, but the goal is the same. A farmer's fields are supposed to produce food. That's the goal of farming.
