Most U.S. farms -- 98 percent in 2007 -- are family operations, and even the largest farms are predominantly family run. Large-scale family farms and non-family farms account for 12 percent of U.S. farms but 84 percent of the value of production. In contrast, small family farms make up most of the U.S. farm count but produce a modest share of farm output. Small farms are less profitable than large-scale farms, and their operator households tend to rely on off-farm income for their livelihood. Farm operator households cannot be characterized as low-income when both farm and off-farm income are considered. Nevertheless, limited-resource farms still exist and account for 3 to 12 percent of family farms, depending on how ¿limited-resource¿ is defined. Graphs.

The complete story of what we don't know, and what we should know, about American food production and its effect on health and the environment. We don't think much about how food gets to our tables, or what had to happen to fill our supermarket's produce section with perfectly round red tomatoes and its meat counter with slabs of beautifully marbled steak. We don't realize that the meat in one fast-food hamburger may come from a thousand different cattle raised in five different countries. In fact, most of us have a fairly abstract understanding of what happens on a farm. In America's Food, Harvey Blatt gives us the specifics. He tells us, for example, that a third of the fruits and vegetables grown are discarded for purely aesthetic reasons; that the artificial fertilizers used to enrich our depleted soil contain poisonous heavy metals; that chickens who stand all day on wire in cages choose feed with pain-killing drugs over feed without them; and that the average American eats his or her body weight in food additives each year. Blatt also asks us to think about the consequences of eating food so far removed from agriculture; why unhealthy food is cheap; why there is an International Federation of Competitive Eating; what we don't want to know about how animals raised for meat live, die, and are butchered; whether people are even designed to be carnivorous; and why there is hunger when food production has increased so dramatically. America's Food describes the production of all types of food in the United States and the environmental and health problems associated with each. After taking us on a tour of the American food system—not only the basic food groups but soil, grain farming, organic food, genetically modified food, food processing, and diet—Blatt reminds us that we aren't powerless. Once we know the facts about food in America, we can change things by the choices we make as consumers, as voters, and as ethical human beings
