Scene 2 (3s)
[Audio] What is it? Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons..
Scene 3 (27s)
[Audio] Environmental impacts. The drilling and extraction of gas from wells and its transportation in pipelines results in the leakage of methane, the primary component of natural gas. Methane is 34 times stronger than CO2 at trapping heat over a 100-year period and 86 times stronger over 20 years. Studies as well as field and aerial measurements have shown that high rates of methane leakage can be found throughout the natural gas system..

Scene 7 (1m 41s)
[Audio] History. Natural gas can come out of the ground and cause a long-burning fire. In ancient Greece, the gas flames at Mount Chimaera contributed to the legend of the fire-breathing creature Chimera. In ancient China, gas resulting from the drilling for brines was first used by about 400 BC. The Chinese transported gas seeping from the ground in crude pipelines of bamboo to where it was used to boil salt water to extract the salt in the Ziliujing District of Sichuan. Natural gas was not widely used before the development of long distance pipelines in the early twentieth century..
