Abstract
A living thing nurturing device for nurturing plants which absorb carbon dioxide and produce oxygen and funguses or fish produce oxygen and produce carbon dioxide comprises a first air-tight receptacle for the nurturing plants and a second air-tight receptacle for nurturing the funguses or fish. Air in the first air-tight receptacle containing a sufficient amount of oxygen is supplied into the second air-tight receptacle and air in the second air-tight receptacle containing a sufficient amount of carbon dioxide is supplied into the first air-tight receptacle. A water tank is installed in the first air-tight receptacle and the temperature of water contained in the water tank is controlled at a value a little lower than the temperature suitable for nurturing the plants, and air containing a sufficient amount of carbon dioxide emitted from the second air-tight receptacle is supplied through the water tank into the first air-tight receptacle. Other water tank is installed in the second air-tight receptacle and the temperature of water contained in the another water tank is controlled at a value higher than the temperature suitable for nurturing the funguses, and air containing a sufficient amount of oxygen emitted from the first air-tight receptacle is supplied through the other water tank into the second air-tight receptacle.
