The latter two risk categories are particularly common among slash and burn subsistence farmers. It is reasonable to expect that as the human population continues to grow, so do these problems. Consensus among demographers regarding estimates of the rate at which the global human population will increase is difficult to achieve, but most agree that over the next 50 years, the number will increase to at least.2 billion (30). It is also conceded by some of the worlds leading agronomists that they will require an additional10 9 hectares of land (roughly the size of Brazil) if they are to produce enough food by conventional methods to meet their needs (31). Since there is essentially no high quality land remaining for this purpose, it seems obvious that a major crisis of global proportion may well be looming on the very near horizon. Limited resources (food, water, and shelter) are some of the major causes for civil unrest and war throughout the world. Vertical farming practiced on a large scale in urban centers has great potential to:. Supply enough food in a sustainable fashion to comfortably feed all of humankind for the foreseeable future;.

Their use has become routine in many situations, particularly in factory farms. Agricultural runoff, which typically contains all of the above-mentioned classes of chemicals, and is also often laden with unhealthy levels of heavy metals, as well, is generally acknowledged as the most pervasive and destructive form of water pollution, degrading virtually every freshwater aquatic environment that. Many of the earths most impacted regions (i.e., get those with the highest population densities) are generally conceded to be unhealthy places to live (western Europe and North America excepted with infant morbidity/mortality rates many times greater than those found in Europe and North America (11). These are the same places from which new kinds of emerging and known varieties of re-emerging infections are found (12). Many of them are zoonotic and their life cycles would not normally include humans were it not for encroachment, an activity driven by the need to expand farming into the natural landscape (13). Nonetheless, there is at present a wide variety of produce available, and in quantity (table 3 for those that can afford. Ironically, many millions of people living predominantly throughout the tropics and sub-tropics are severely malnourished, while living within countries many of which export large amounts of agricultural products destined for the markets of the developed world. Farming is an occupation fraught with a wide variety of health risks (14, 15, 16, 17, 18, 19, 20). Numerous infectious disease agents (e.g., schistosomes, malaria, geohelminths) take advantage of a wide variety of traditional agricultural practices (irrigation, plowing, sowing, harvesting facilitating their transmission (Table 1) (21, 22, 23, 24, 25). These diseases take a huge toll on human health, disabling large populations, thus removing them from the flow of commerce, even in the poorest of countries. Other health risks to farmers include acute exposure to toxic agrochemicals (e.g., pesticides and fungicides) (26 bites from noxious wildlife (27 and trauma injuries (28, 29).

These land-use estimates include grazing lands (formerly grasslands) for cattle, and represents nearly 85 of all land that can support at least a minimum level of agricultural activity. In addition, farming produces a wide variety of feed grains for many millions of head of cattle and other species of domesticated farm animal (2). In 2003, nearly 33 million head of cattle were produced in the United States, alone (3) In order to support this large a scale of agricultural activity, millions of hectares of hardwood forest (temperate and tropical grasslands, wetlands, estuaries, and to a lesser extent coral. The advantages of farming are obvious enough from word a human perspective, but even our earliest efforts caused irreversible damage to the land. For example, some 8,000 to 10,000 years ago, the fertile, silt-laden soils of the floodplains of the tigris and Euphrates river valleys were rapidly degraded below minimum food production limits due to erosion caused by intensive farming and mis-managed irrigation projects that were often interrupted. Today, primitive farming practices continue to produce massive loss of topsoil (5, 6 while excluding the possibility for long-term carbon sequestration in the form of trees and other permanent woods plants (7). Agrochemicals, particularly fertilizers, are used in almost every major farming system regardless of location (8 largely due to the demand, year in and year out, for cash crops that extract more nutrients from the substrate that it can provide. Mono-crops are extraordinarily vulnerable to a wide range of insect pests and microbial disease agents due to the very nature of farming (i.e., growing large numbers of a given plant species in a confined area). To mount a counter-offensive, we have invented pesticides and herbicides.

Novel ways for obtaining an abundant and varied food supply without encroachment into the few remaining functional ecosystems must be father's seriously entertained. One solution involves the construction of urban food production centers vertical farms in which our food would be continuously grown inside of tall buildings within the built environment. If we could engineer this approach to food production, then no crops would ever fail due to severe weather events (floods, droughts, hurricanes, etc.). Produce would be available to city dwellers without the need to transport it thousands of miles from rural farms to city markets. Spoilage would be greatly reduced, since crops would be sold and consumed within moments after harvesting. If vertical farming in urban centers becomes the norm, then one anticipated long-term benefit would be the gradual repair of many of the worlds damaged ecosystems through the systematic abandonment of farmland. In temperate and tropical zones, the re-growth of hardwood forests could play a significant role in carbon sequestration and may help reverse current trends in global climate change. Other benefits of vertical farming include the creation of a sustainable urban environment that encourages good health for all who choose to live there; new employment opportunities, fewer abandoned lots and buildings, cleaner air, safe use of municipal liquid waste, and an abundant supply. Introduction, as of 2004, approximately 800 million hectares of land were in use for food production approximating an area equivalent to Brazil (1 and allowing for the harvesting of an ample food supply for the majority of a human population approaching.3 billion.

It has re-arranged the landscape in favor of cultivated fields at the expense of natural ecosystems, reducing most natural areas to fragmented, semi-functional units, while completely eliminating many others. A reliable food supply was the result. This singular invention has facilitated our growth as a species to the point now of world domination over the natural world from which we evolved. Despite the obvious advantage of not having to hunt or scavenge for our next meal, farming has led to new health hazards by creating ecotones between the natural world and our cultivated fields. As the result, transmission rates of numerous infectious disease agents have dramatically increased- influenza, rabies, yellow fever, dengue fever, malaria, trypanosomiasis, hookworm, schistosomiasis and today these agents emerge and re-emerge with devastating regularity at the tropical and sub-tropical agricultural interface. Modern agriculture employs a multitude of chemical products, and exposure to toxic levels of some classes of agrochemicals (pesticides, fungicides) have created other significant health risks that are only now being sorted out by epidemiologists and toxicologists. As if that were no enough to be concerned about, it is predicted that over the next 50 years, the human population is expected to rise to at least.6 billion, requiring an additional 109 hectares to feed them using current technologies, or roughly the. That quantity of additional arable land is simply not available. Without an alternative strategy for dealing with just this one problem, social chaos will surely replace orderly behavior in most over-crowded countries.

Apply this to problem skin such as areas with acne or take one tablespoon before meals for flatulence and digestive problems. More importantly, enjoy another gift from Nature! Abstract, the advent of agriculture has ushered in an unprecedented increase in the human population and their domesticated animals. Farming catalyzed our transformation from primitive hunter-gatherers to sophisticated urban dwellers in just 10,000 years. Today, over 800 million hectares is committed to soil-based agriculture, or about 38 of the total landmass of the earth.

The seeds can also be added to casseroles or breads, used in canning, or extracted in wine or vinegar. Some people grind the seeds and mix them with honey or sprinkle them on salads. They make a nice addition to salad dressings and even stir fry dishes, especially when combined with lemon, cilantro, and tahini.

It's best to use a double boiler or be lazy (like me) and use a yogurt maker because the temperature is very even so you can safely ignore the process for hours. The oil will darken. When you feel this has been warmed long enough, melt a little beeswax into the warm oil. Stir it with a glass rod or new chopstick. If you like, you can add an essential oil or combination of oils just before the beeswax stiffens.

Black cumin is long particularly useful in aggressive cancers whose growth depends on angiogenesis. In vitro studies performed in Jordan and the United States have determined that the volatile oil is anti-leukemic. Studies performed in Spain as well as England found that the fixed oil is useful in the treatment of rheumatism and other inflammatory diseases. This property is attributed to thymoquinone which is as high as 25 in the Egyptian seed and missing entirely is some seeds. Culinary Uses, black cumin seeds are small. They can be used to make tea by simply pouring hot water over the seeds and letting the brew steep for 10 minutes, about a tablespoon makes a nice cup of tea, but it is better to keep the cup covered until ready to drink.

This is not unimaginable if the protein nutrients are sufficient to correct deficiency conditions. Protects healthy cells and Stimulates Production of Natural Interferon. The first major study of Nigella sativa in cancer prevention and treatment was performed by scientists at Cancer Immuno-biology laboratory of Hilton head Island, south Carolina. They concluded that a healthy immune system will detect and destroy cancer cells before the cancer endangers the patient. The immune system does this by supporting increased production of immune cells, bone marrow cells, and B-cells that produce antibodies. Black cumin stimulates neutrophil activity. These are the short-lived immune cells that are normally found in bone marrow but mobilized into action when there is a bacterial infection. Extracts of black cumin have also been shown to modulate production of interleukins, a quality it shares with some other highly revered herbs: ginseng, astragalus, mistletoe, garlic, and cat's claw. In animal studies, while none of the subjects in the control group survived, two-thirds of the mice that had been given black cumin seed oil were still alive 30 days after deliberate efforts to cause cancer in the subject groups.

be eliminated before the symptoms of immune weakness subside. Continued use for six months or longer tends to give outstanding results. For extreme fatigue, consider mixing some crushed seeds with some royal jelly. With a seed containing so many constituents and having such a long ethnobotanical history, it is not surprising that many throughout the mediterranean and Asia believe that black cumin is basically good for all that ails. However, the claims are not outrageously far-fetched if one considers how complete the seeds are in terms of their many chemical constituents. Still, it is understandable that anyone who claims that something can do anything from increasing one's sperm count or increasing milk production in a nursing mother to relieving bronchial conditions such as asthma and bronchitis, is not taken seriously. One then wonders if the imagination of the poets has triumphed over the logic of scientists? Just remember: those paying homage to the black seeds of the Egyptian oases were praising the capacity of the seeds to restore normalcy, not cure.

Though it is the oil that is most often used medicinally, the seeds are a bit spicy and are often used whole in cookingcurries, pastries, and Mediterranean cheeses.

Black cumin, especially when combined with garlic, is regarded as a harmonizer of the imbalance which allows immune cells to destroy healthy cells. The technical language to describe this property is "immunomodulatory action." The difference between black cumin and interferon is that there are no known side effects with black cumin when administered in normal dosages.

Nigella sativa is one the most revered medicinal seeds in history. The best seeds come from Egypt father's where they grow under almost perfect conditions in oases where they are watered until the seed pods form. Black cumin seeds were found in the tomb of Tutankhamun. Though black cumin seeds are mentioned in the bible as well as in the words of the Prophet Mohammed, they were not carefully researched until about forty years ago. Since this time, more than 200 studies have been conducted in universities. The famous Greek physician dioscorides used black cumin seeds to treat headaches and toothaches. Mohammed said that black cumin cures every disease but death itself. The reason might be found in the complex chemical structure of the seeds. These little seeds have over one hundred different chemical constituents, including abundant sources of all the essential fatty acids.
