Natural Gas, composed mainly of methane with some other hydrocarbons, is categorised as conventional or unconventional depending on its source.
– Conventional gas exists in large offshore reservoirs and onshore reservoirs and is often found when drilling for oil.
– Unconventional gas is ‘natural gas’ trapped in geological strata that is difficult to mine in the conventional manner and which generally requires specialised mining procedures, such as hydraulic fracturing (fracking).
There are serious threats to human health from unconventional gas development at many levels. They relate to community health, water and air pollution, water shortages, permanent degradation of productive agricultural land and loss of livelihood and landscape.
