http://www.energybulletin.net/22584.htmlThere was a time not so long ago when famine was an expected, if not accepted, part of life. Until the 19th century—whether in China, France, India or Britain—food came almost entirely from local sources and harvests were variable. In good years, there was plenty—enough for seasonal feasts and for storage in anticipation of winter and hard times to come; in bad years, starvation cut down the poorest and the weakest—the very young, the old, and the sickly. Sometimes bad years followed one upon another, reducing the size of the population by several percent. This was the normal condition of life in pre-industrial societies, and it persisted for thousands of years.
Today, in America, such a state of affairs is hard to imagine. Food is so cheap and plentiful that obesity is a far more widespread concern than hunger. The average mega-supermarket stocks an impressive array of exotic foods from across the globe, and even staples are typically trucked from hundreds of miles away. Many people in America did go hungry during the Great Depression, but those were times that only the elderly can recall. In the current regime, the desperately poor may experience chronic malnutrition and may miss meals, but for most the dilemma is finding time in the day’s hectic schedule to go to the grocery store or to cook. As a result, fast-food restaurants proliferate: the fare may not be particularly nutritious, but even an hour’s earnings at minimum wage will buy a meal or two. The average American family spent 20 percent of its income on food in 1950; today the figure is 10 percent.
This is an extraordinary situation; but because it is the only one that most Americans alive today have ever experienced, we tend to assume that it will continue indefinitely. However there are reasons to think that our current anomalous abundance of inexpensive food may be only temporary; if so, present and future generations may become acquainted with that old, formerly familiar but unwelcome houseguest—famine.
The following are four principal bases (there are others) for this gloomy forecast.
