Reading Responses about “healthy Growth for U.S. farms”
Agriculture has fueled the eruption of human civilization. Efficiently raised, affordable crops and livestock feed our growing population, and hunger has largely been banished from the developed world as a result. Yet there are reasons to believe that we are beginning to lose control of our great agricultural machine. The security of our food supply is at risk in ways more noxious than anyone had feared.
The trouble starts with crops. Orange groves in Florida and California are falling to fast-moving blights with no known cure. Cavendish-variety bananas the global standard, each genetically identical to the next will almost certainly be wiped out by emerging infectious disease, just as the Cavendish’s predecessor was six decades ago. And as entomologists Diana Cox-Foster and Dennis vanEngelsdorp describe in “Saving the Honey bee,” on page 40, a mysterious affliction has ravaged honeybee colonies around the U.S., jeopardizing an agricultural system that is utterly dependent on farmed, traveling hives to pollinate vast swaths of monoculture. The ailment may be in part the result of the stresses imposed on hives by this uniquely modern system.
Plants and animals are not the only ones getting sick, however. New evidence indicates that our agricultural practices are leading directly to the spread of human disease. Much has been made in recent years of MRSA, the antibiotic-resistant strain of Staphylococcus bacteria, and for good reason. In 2005, the most recent year for which figures are available, about 95,000 MRSA infections caused the deaths of nearly 19,000 Americans. The disease first incubated in hospitals the killer bacterium is an inevitable evolutionary response to the widespread use of antibiotics but has since found a home in locker rooms, prisons and child care facilities. Now the bacteria have spread to the farm.
Perhaps we should not be surprised. Modern factory farms keep so many animals in such a small space that the animals must be given low doses of antibiotics to shield them from the fetid conditions. The drug-resistant bacteria that emerge have now entered our food supply. The first study to investigate farm-bred MRSA in the U.S. amazingly, the Food and Drug Administration has shown little interest in testing the nation’s livestock for this disease recently found that 49 percent of pigs and 45 percent of pig workers in the survey harbored the bacteria. Unfortunately, these infections can spread. According to a report published in Emerging Infectious Diseases, MRSA from animals is now thought to be responsible for more than 20 percent of all human MRSA cases in the Netherlands.
In April 2008 a high-profile commission of scientists, farmers, doctors and veterinarians recommended that the FDA phase out the nontherapeutic use of antibiotics in farm animal production, to “preserve these drugs to treat sick animals, not healthy ones” in the words of former Kansas governor John Carlin, the commission’s chair. The FDA agreed and soon announced that it would ban the use of one widespread antibiotic except for strictly delineated medical purposes. But five days before the ban was set to take effect, the agency quietly reversed its position. Although no official reason was given, the opposition of the powerful farm lobby is widely thought to have played a role.
This is just one example of a food production system that protects a narrow set of interests over the nation’s public health. Simple measures such as the reinstatement of the FDA’s initial ruling are necessary and important steps. But Congress needs to take a far more comprehensive approach to realign the country’s agricultural priorities with its health priorities, to eliminate subsidies that encourage factory farming, and to encourage the growth of polyculture and good old-fashioned crop rotation in the U.S. As the world is quickly learning, a civilization can only be as healthy as its food supply.

The purpose of this assignment is to practice organizing data through ordering and grouping variables. Data often appear disordered and it is difficult to see any connections or relationships. Ordering the data by certain variables or grouping variables into specific categories, such as age or sex categories, can help bring clarity to the data. Knowing how to organize data is an important skill to initiate the analytical process. For this assignment, students will use Excel and SPSS Statistics to order variables. Using the “Example Dataset,” complete the steps below using both Excel and SPSS Statistics. View the Excel and SPSS tutorials for assistance in completing this assignment. Submit one Word document and include a screen shot of the data after completing the first two steps of Part 1 in Excel and SPSS to compare your results. Use a second Word document to complete Part 2 of the assignment. Part 1: Ordering and Grouping Data Using Excel and SPSS For Part 1, accomplish the following: — Order (sort) observations according to age. — Group observations by sex and investigate the age and income for males and females. — Create a new variable titled “Exercise Group” based on the variable “Minutes Exercise.” — Use the following categories to create your groups: 1 = 0-30 minutes; 2 = 31-60 minutes; 3 = 61-90 minutes; 4 = 91-120 minutes; and 5 = 120+ minutes. Part 2: Data Interpretation Study the results of the dataset grouping and ordering. Discuss the following in a 500-750 word summary: — Describe the measurement levels for each of the variables in the dataset. – Discuss what you learned from ordering the data by age and why this information is important. – Describe the process you used to group the data in Excel and SPSS. – Describe what you learned by grouping the variables by category of exercise. — Are these data from a correlational study, experimental study, or quasi-experimental (observational) study? Discuss your rationale and identify a study question appropriate for this dataset.
