PROBLEM TO BE SOLVED: To solve such a problem that global warming threatens human life and changes even the environmental system, one of causes of the global warming is carbon dioxide and the unnecessary carbon dioxide must be removed from the air first of all without controversy in order to stop the global warming right now, and the global warming must be stopped by our efforts for posterity or for nowadays as soon as possible before it is too late. SOLUTION: Soil is utilized to make the energy consumption as low as possible. There are various types of soils, for example, red clay soil having high iron content, corrupted soil, shield clay and eroded sandy soil. Carbon dioxide is combined with molecules and mineral-containing molecules in the soils of these types and removed from the air. As one method, the soil is lumped and air is contacted with the lumped soil so that the carbon dioxide in the air is combined with molecules in the soil and removed. COPYRIGHT: (C)2011,JPO&INPIT
