Sunday, always the land.





Cultivation, vineyards and Olive groves





and...



most wonderful bush, uncultivated land 






....always changing sky

All we have,

.... unscrupulous governments allow unscrupulous corporations destroy the land and water for ever,  with short term Coal seam mining.

Coal seam gas (CSG) mining is an invasive form of unconventional gas mining.  It usually involves tens of thousands of gas wells, with roads, pipelines, compressor stations, wastewater dams, and other infrastructure.  A CSG project can spread across hundreds of thousands of hectares of land.

What are the risks?
There have been numerous risks and problems identified with invasive CSG gasfields.  These include encroachment on good farming land, disruption of other land uses and industries, clearing of bushland, air pollution, contamination or depletion of ground or surface water, pollution of waterways, health impacts on workers and nearby residents, and damage to biodiversity.

How is coal seam gas extracted?
Coal seam gas is extracted by drilling a well vertically through rock strata until reaching the coal seam, at which point the well may also be drilled out horizontally to increase access to the methane gas. Coal seams contain both water and gas. During coal seam gas operations the water must be pumped out of the coal seam to lower the pressure and allow the gas to flow to the surface.

Hydraulic fracturing, more commonly known as fracking  is used to stimulate and accelerate the flow of coal seam gas. The process involves high pressured injection of sand, water and chemicals into the coal seam gas well. The injection causes fractures in the coal seam allowing the gas to flow to the surface of the well.
There are significant concerns associated with hydraulic fracturing including the potential to contaminate water sources and cause earthquakes. A report by the Committee for Economic Development of Australia[1] said: "In addition to concerns over contamination of aquifers from the chemicals added to fracking fluid, issues have also been raised about contamination of water supplies from fugitive gas after fracking, and seismic activity and tremors associated with the drilling and fracking process".
Fracking has been used during coal seam gas operations in both Queensland and New South Wales.
