Coal seam gas (CSG), also known as coal bed methane (CBM), is a naturally occurring methane gas found in most coal seams. The extraction of CSG involves drilling wells into the coal seams and bringing water from the seams to the surface. This process reduces the pressure in the seams and allows the gas to be released from pores (Lacey and Lamont, 2014). The growing environmental and health risks associated with coal seam gas fracking production has the potential to generate considerable gas emissions, can strain water resources, result in water contamination, may have negative impacts on public health such as noise pollution, on biodiversity, food supply, as well as on soil (Peduzzi, 2013). This critical review will investigate the required techniques of extracting of coal seam gas and how these techniques are affecting our environment and creating health hazards around high populated areas. Moreover it will identify socio-economic problems associated with the extraction of coal seam gas as well as its benefits. Furthermore it will look into the political overview and potential prevention strategies that can be used to decrease the environmental and human impact it is having.

About 40,000 wells are being drilled in the state in the coming decades. Pipelines range up to 500 kilometres long are also under construction to transport this gas from production sites throughout the Surat and Bowen Basins to industrial facilities at Curtis Island near Gladstone where the coal seam gas will be converted into liquefied natural gas (LNG) for export (Mercer, 2014). More mines have been developed across Queensland and into New South Wales and all across Australia. The development is fast moving because of the global interest in the industry and increase in the demand for gas around the world. Countries are paying good money for the exportation of gas. With the increase of demand comes the increase in
