A method for dumping carbon dioxide gas into the ground of the sea bottom comprises injecting carbon dioxide gas into the ground of the sea bottom to fix the carbon dioxide gas in the ground of the sea bottom. A method for dumping carbon dioxide gas into the ground of permafrost regions comprises boring a well and injecting carbon dioxide into the ground to fix carbon dioxide in the ground. A method for recovering and consuming natural gas found in the ground of permafrost regions with low pollution comprises exploiting and consuming hydrate of natural gas present in permafrost regions to produce carbon dioxide as a by-product and injecting the carbon dioxide by-product into the ground of permafrost. A method for gathering natural gas by using dumped carbon dioxide gas as a heat generating source comprises injecting carbon dioxide gas or liquefied carbon dioxide gas into layers of hydrate of natural gas present in the ground of the sea bottom or in permafrost regions. An apparatus for gathering natural gas by using carbon dioxide gas as a heat generating source comprises an injection pipe for injecting carbon dioxide, a pressure injection apparatus for injecting carbon dioxide, a gathering pipe for gathering a mixed gas containing natural gas separated from the layers of hydrate of natural gas and carbon dioxide and a gas separator for separating natural gas from the gathered mixed gas.
