Nearly twenty years after its initial publication, Dr. Bernard Jensen’s sobering picture of just how interconnected man is with the earth, and how this connection is being destroyed – link by link – still resonates powerfully. In this eye-opening account of the inherent dangers in our agricultural system, Jensen looks at the better-known manmade disasters, such as the greenhouse effect, as well as the ecological and subsequent health related problems hidden from the general public at the time. Empty Harvest is a groundbreaking book that examines just what the total problem was and still is.

“In a day when it is cheap and easy to be a doomsday prophet, Empty Harvest shines like a bright beacon of hope and ecological sanity. While exposing the dire consequences of thinking we can grow healthy food with poisons, this excellent book defines positive alternatives, and demonstrates their power to restore us to true health. Empty Harvest lights the way toward living in harmony and happiness with the forces of life.”
--John Robbins, author of Diet for a New America

Lush Fields Belie an Empty Harvest


Soil and Civilization

Healthy soil is America’s greatest natural resource. But few realize that the current state of widespread soil erosion in North America threatens our way of life. It may seem hard to believe, but only a few inches of topsoil stand between you, me, and starvation. Just what makes care of the topsoil so important? There are several things to consider.

First, soil is the medium for all plant life. What is popularly called topsoil is the rich, nutrient-laden cover of the Earth’s crust from which food crops draw their sustenance. Underneath the topsoil there may be clay, shale, or rock—substances that do not support food crops. It is only in the precious shallow topsoil that plants are seeded, germinated, sprouted, nurtured, and grown. These plants serve as food for animals on the lowest ends of the food chain. Animals that eat these plants supply food to animals on the highest ends of the food chain.

Second, attention to topsoil is important because topsoil is easily exhausted from lack of care. The best farmers replenish the soil as it is farmed. Unfortunately, this practice has become an exception to the rule. Results of ignorance of proper agricultural methods can be seen in every country on Earth. Even in the Amazonian tropical rain forest, where many of us might assume that topsoil is extra rich due to the intense heat, humidity, and rapid decomposition of surrounding plants, topsoil exhaustion is epidemic. In this area of the world, farmers continue to practice a form of slash-and-burn agriculture. They cut down several acres of trees and vegetation, burn it, and then plant their crops. In a few seasons, the land is as barren and sterile as a desert. Then, they move on. Needless to say, this practice does not help the soil quality.

Third, care of topsoil is important because it is dependent on life around it to retain its own life-giving properties. One of the main reasons for the famine in East Africa today is lack of topsoil brought about by massive deforestation. At the turn of the century, 90 percent of Ethiopia’s land was covered by forests. Less than a century later, not 5 percent of that forest remains. How did this occur? With the trees cut down for easy profit, the rain water—instead of soaking into the topsoil—rushed down the hillsides, flooded the valleys, and carried the earth off with it. The trees had shaded the soil, and the roots had acted as pumps, drawing water up near the surface of the ground, keeping the water table high. But now they were gone. Without tree roots to keep the water table high, the soil was exposed to sun, wind, and rain. It was baked dry, washed away into streams, rivers, and oceans, or simply blown away. Without soil in which to grow plants to feed animals and humans, mass starvation soon resulted.

Care of our forests cannot be overstressed. This is because the destruction of any kind of forest causes great imbalance in the planet’s ecosystem. Trees are vitally important not only for soil stability but also because they give us our human breath, and we give them theirs. Trees release oxygen and consume carbon dioxide. Humans do the reverse.

Further, deforestation without replanting is a threat to nature because it kills non-hybrid progenitor trees and plants. For instance, the progenitor of all coffee bean trees is from Ethiopia. If the last of these trees died from neglect, the hybrid species would become the ultimate source of coffee beans. But if the hybrid coffee bean trees around the world were then killed by some species-specific disease or agricultural malaise, there would be no original seed to fall back upon. Then, coffee bean trees—not to mention coffee breaks—would become extinct. While coffee is not a matter of life and death, this example of how biology impacts sociology is one that the Earth’s inhabitants might do well to ponder.


Some soil erosion is natural. Wind picks up dust, and rain washes it away. Normally, nature can manage to replace the loss, slowly weathering sand and clay from rock, and mixing it with organic matter. But our destructive approach toward agriculture and development speeds erosion rates far beyond what nature can replace.

Highway construction, for instance, can accelerate erosion 200 times the natural rate. In just a matter of months, shopping-center development, surface mining, logging, and off-road vehicles can obliterate topsoil that nature took a thousand years to create—and needs a thousand years to replace.

Just how much damage has man done? In Iowa, topsoils that were once a foot deep today are less than six inches deep. Although it doesn’t sound like much, six inches can be devastating. The United States Department of Agriculture estimates that a six-inch loss of topsoil, such as the current one in the southern Piedmont, is capable of reducing crop yields by 40 percent per year. Though crop loss and deforestation are bad enough, they are not the only soil erosion stories.

Soil erosion interferes with wildlife in many ways. When soil fertility is reduced, there is less life in the soil. That means less food for all animals—from the worms and insects to the birds that eat them to the larger animals that eat birds and, finally, to humans. Soil erosion kills water ecosystems, as well. The silt that accumulates in lakes because of runoff causes the lakes to grow shallower. Then the weeds proliferate, choking off oxygen needed by fish. Fish die, and the same negative sequence of events—only in an aquatic setting—occurs.

My teaching and traveling experiences have made me aware that people are not taught how intricately their lives are woven with the life of their land. This ignorance is reflected in abusive agricultural methods. It is reflected in the way people eat, accepting into their bodies foods grown on sterilized, poisoned soils that have all too few nutrients to impart to the plant—or to them.


Geologists say there are 58 million square miles of land surface on the Earth, but only 10 million square miles of this can be farmed. It takes about two acres of land to feed one person for a year. But, right now, there is only one acre per person, and not all of this is good land. That is why, in my opinion, about two-thirds of the people of the world go to bed hungry every night.

Fortunately, the United States has enough land to feed its people well. But there are still serious problems with the way we use our land. More than half of the agricultural land of the United States has been severely eroded or farmed incorrectly. According to the United States Department of Agriculture, of our current 421 million acres of productive farmlands, 97 million acres are eroding at more than twice the “tolerance” level—the level at which soil can be replaced naturally. Another 89 million acres are eroding at one to two times that tolerance level. In all, nearly 40 percent of our farmlands are losing topsoil.

Ecologist Gene Logsdon wrote, “The fall of almost every civilization is largely on account of raping natural resources until all the easy profit goes out of them.” By the 1930s, most of the “cream” had been skimmed off of American soils, and diminished crops of mineral-deficient vegetables, fruits, and grains began to appear. Interestingly, chronic, degenerative diseases began to escalate at this time, as well—arthritis, diabetes, cancer, lupus, osteoporosis, and dental caries.


Over a sixty-year period, I have witnessed the deterioration of our planet and its life-giving systems, and the degenerative effect this has had on people.

My observations have led me to conclude that we should understand that people with nutritional deficiencies and toxic accumulations are not just “less healthy” than other people. We cannot separate the body from the mind or from the spirit. Any person with impaired wellness at the physical level is, to some degree, impaired mentally and morally. The mind does not work as well. The strength of will that is so important in living a life of integrity is lowered.

In fact I have never failed to notice, though I loved all my patients, that the sickest among them were the most mentally ill, morally weak, and emotionally imbalanced.

Also aware of this relationship was my late friend, J. I. Rodale, of the Rodale natural foods publishing empire. He often said he believed there was a correlation in the fact that my ancestral home of Denmark boasted two dubious world records: Number One in both its use of artificial fertilizers and its annual suicide rate. Rodale said he felt there was a connection between Denmark’s dead soil and its dead people.

But, luckily, the effects of dead soil can be reversed. As I taught my patients to cleanse and correctly feed themselves, as they restored themselves to physical health, my greatest joy was in witnessing the mental, moral, and emotional recovery that also occurred in them.


The Bible says that man is made of the dust of the Earth. The same chemical elements found in soil make up our bodies. The only difference between the two is that the human molecular structure is more complex. Human bodies require nutrition found in the form of plants, meat, milk, and eggs.

But all animals get their food directly or indirectly from plants, and all plants get their food from the soil. Therefore, mineral-deficient soil may be one of the greatest original sources of disease in the world today. According to D. W. Cavanaugh, M.D., of Cornell University, “There is only one major disease and that is malnutrition. All ailments and afflictions to which we may fall heir are directly traceable to this major disease.” Simply stated, food crops grown on depleted soil produce malnourished bodies, and disease preys on malnourished bodies.

A few of the trace minerals necessary for plant health and resistance are: magnesium, zinc, iron, copper, calcium, boron, manganese, molybdenum, cobalt, and chromium. But the absence of one element from the soil can cause great health problems. For instance, if inorganic cobalt is missing in the soil, the plant cannot absorb it and convert it to organic cobalt. Without organic cobalt, the human body cannot manufacture vitamin B12. When we don’t get enough vitamin B12, we can’t assimilate iron properly or make strong red blood cells; we become anemic. Anemic people become weak, depressed, and vulnerable to disease.


I want you to have a look at Table 1.1, the German chemist Wilhelm Koenigs’ famous list of chemicals that compose the human body. I want you to consider briefly what happens to your body when you are missing one or more of these elements.

Table 1.1 Koenigs’ Analysis of Chemical Elements in an Average Mature Male

When the body lacks one or more chemical element, the tissue structure is weakened, the cell function is impaired, and health problems can develop. The reason for this is nutrients combine in the body to form such critical materials as hormones, enzymes, and proteins. If the body is missing zinc and chromium, for instance, the pancreas cannot properly manufacture the hormone insulin. The inability of the pancreas to manufacture insulin results in diabetes, a degenerative condition in which the tissues are unable to obtain sugar from the blood.

Meet the Author

Dr. Bernard Jensen was one of America’s pioneering nutritionists and iridologists. Beginning his career in 1929 as a chiropractor, he soon turned to the art of nutrition for his own health problems. He observed firsthand the cultural practices of people in more than fifty-five countries, discovering important links between food and health. In 1955, Dr. Jensen established the Hidden Valley Ranch in Escondido, California as a retreat and learning center dedicated to the healing principles of nature where he saw firsthand the value of nutrition and iridology.

Over the years, Dr. Jensen received many honors and awards, including Knighthood in the Order of St. John of Malta; the Dag Hammarskjold Peace Award of the Pax Mundi Academy in Brussels, Belgium; and an award from Queen Juliana of the Netherlands for his nutritional work. In 1982, he also received the National Health Federation’s Pioneer Doctor of the Year award.

Mark Anderson is a recognized authority on the topics of global ecology and wholistic health. He has spent years traveling the world to study and teach clinical nutrition from the soil up. His stimulating and informative lectures on traditional diets, health patterns of native peoples, and agriculture have been featured at seminars and conferences in Africa, Asia, Europe, and India, as well as throughout the United States and Canada. Mark’s articles about natural approaches to nutrition and health have been published in scores of professional health journals in the United States.
