  skos:definition """Methane (CH4) is a colorless, odorless, flammable, greenhouse gas. It
is released naturally into the air from marshes, swamps, rice
fields, ruminant animals (such as cattle), and sewage sludge.  CH4 is
also released from methane-producing bacteria (methanogens) that live
in anaerobic places. [Solar Energy; v52n6; 467-477; 1994.] [Air, The
