The coastline in Kanto Plain of the Jomon period

　
It is writing down IPCC (the panel among the governments about the climate change). If not taking a measure in the present condition, in 2100, the average temperature of the earth rises about 1 - 3℃ , and the surface of the sea rises by 50 cm in the world average." That the temperature rises to here among 100 years only is indeed " A malfunction " for the earth. Because, when Japan was Zyomon era about 6000 years before from now, the part on the Kanto plains was a bottom of the sea.

Making a desert

In the tropical and subtropical area, the production of the food declines and the danger of the hunger in the poorest area which contains the dry and half dry area will increase.

There are a natural factor and an artificial factor in the cause of making a desert. As for the natural factor, the earth climate change still concerns and the global warming, too, is related mainly. It says that the climate change accelerates to make a desert in the area where to make a desert is progressing. Another artificial factor accounts for most of the cause of making a desert. Mainly, grazing too much, tillage too much, surplus absorption by the fuel material and so on are given. The human being and the animal are consuming green at the speed that exceeds green's growth. This background includes poverty, population increase, a population movement, a food problem and so on.

A to do the poor farmer surplus tillage centered on the burning field except alternative is different when there is not it and the land is lean gradually. It moves to the land that is. The dryness, the flood, coming to a drought in the half dry place, its saying that the area for which it is easy to suffer damage is fragile specifically to the climate change to making a desert.
