Explanation:

methane is a very volatile gas. it is product from the ruminant digestion (600 L/day from a cow), from the anaerobic fermentation in swamps, in the fields of rice, and from this sources it is difficult to stop. When methane comes from underground deposits it can be regulated from apposite system of piping with shutter valves and security valves but as it is stated in the article, the piping is too old and lacks of maintenace. It is a technologic mistake that we are paying in a very expensive way
