From Time: Getting Real About the High Price of Cheap Food.

Horror stories about the food industry have long been with us – ever since 1906, when Upton Sinclair’s landmark novel The Jungle told some ugly truths about how America produces its meat. In the century that followed, things got much better, and in some ways much worse. The U.S. agricultural industry can now produce unlimited quantities of meat and grains at remarkably cheap prices. But it does so at a high cost to the environment, animals and humans. Those hidden prices are the creeping erosion of our fertile farmland, cages for egg-laying chickens so packed that the birds can’t even raise their wings and the scary rise of antibiotic-resistant bacteria among farm animals. Add to the price tag the acceleration of global warming – our energy-intensive food system uses 19% of U.S. fossil fuels, more than any other sector of the economy.
