We are fortunate to live in a society with abundant food. Most of us take for granted that we will always have enough to eat. If we do have any concerns about food, more than likely they relate to its nutritional value or to reducing the epidemic of obesity. Many of us have never visited a working farm, let alone tried to understand the techniques that farmers use to grow our food. A by-product of the success of modern agriculture is a society where the efforts of the few are adequate to feed the many. This situation allows the vast majority of people to engage in diverse occupations without worrying about the need to grow food to feed their families.
