       The process that goes into putting food on the table in America has changed dramatically in the last 50 years. In the past, most farms were small and labor intensive. They required a relatively large group of highly skilled workers to raise animals and produce food. Antibiotics did not have widespread use. Technology and standardization were less prevalent. Farms were somewhat unique. Present day farms are large and built for mass production. The process is streamlined. Workers are fewer and less skilled. Everything is standardized for maximum efficiency. Animals are fed a specific amount of food to get the greatest return on investment. There is also a widespread use of antibiotics. This leads to the growth of antibiotic-resistant bacteria which leads to a host of other problems, including human and animal disease that can't be treated by drugs.
    Another problem present day farms have is waste treatment. Before, animals weren't confined and their feces was spread out throughout the land they grazed on. Now, with the animals packed together in huge groups, feces is produced at a fast rate in a confined area. Farms are typically in rural areas, away from waste-treatment plants. So this huge amount of waste isn't disposed of properly and can threaten the neighboring human population with disease and water contamination.
  This problem is fixable, but would be detrimental to the IFAP system. Farming could be taken back to the old ways where animals aren't as densely confined. This way manure would be less dense and the problems associated with it would be less severe. The system of farming could be promoted by government subsidies for SMALL farms only.
