             Methane is released into the atmosphere when organic
             material decomposes. Some of the things that produce
             methane but not limited to, are landfills, coalmines,

             twentieth century, twice as fast as carbon dioxide and
             is still increasing at a rate of 1% every year. But
             with that said still many scientists think that the
             increased concentration of methane is
