The food shortage is not a problem only for poor countries
History and an outline
A food shortage is various factors to the thing that as a result of complex, I invite lack, social confusion remarkably, and available resources do as food. It is so-called famine (broad-based starvation), but the outbreak of the chronicity-like situation is concerned about more a wide area.
It is "a famine reaching the critical situation" (concern for or it), but I have an influence on the Great Society using lack of the food namely this, and it is concerned about the status quo of the social system becoming difficult if I say to exact truth.
A population explosion, an area (e.g., it is Japan 40%) of the self-sufficiency ratio that the own country is low in are poor, and what is concerned about as these outbreak factors at the present of the early 21st century falls into it, and it is food import becoming difficult, a bad harvest by global abnormal weather, the large change of the climate by the influence of the global warming, economical confusion such as the world Great Depression, a decline of the food production ability by superabundant switch to biofuel, but the chain of reactions of the price remarkable rise such as the oligopoly by the cereals business firm are concerned about again by a famine.
A problem and the price remarkable rise about the production of cereals for a human being in particular to get activity energy (physiological heat capacity) necessary for life and the staple food crops including the potato let you make the life of a side living a life depending on this difficult, and it is thought that maintenance of the social structure becomes difficult.
Concern about the global warming
As for the global warming, a climate fluctuates on a global scale and includes the decrease of the land area with a rise in sea surface caused by the fusion of various local ice sheets including progress and the South Pole of the desertification that a conventional grain belt is not suitable for a food production.
In addition, a rainstorm is generated frequently, and various problems including the outbreak of the damage from salt breeze are predicted other than the direct damage (flood) caused by wind and rain in the coastal place.
Alternative food resources
It is thought that a problem worsens at a stretch when it becomes hard to use an origin of purveyance from before in the single state that there is it and does it, and depends on the fixed food source of supply by the food shortage. Therefore, I change food resources to other things and plan that it is said to evade a problem by misappropriating more various things as food resources.
The so-called insect food was incorporated in the food culture of an old form including the local cooking traditionally, but, as high quality protein resources, propagative power was relatively strong again, and the insect that the insect food was targeted as for this has been used because it was creature resources provided easily.Seeing from the side that is not used to eating this, it may be hated in a category of the strangeness food, but it is thought that protein resources of the same amount are provided with the feed that there is in comparison with the grazing animals which are bred to get edible meat now fewer it.
