The film explores issues around unconventional shale and coal seam gas extraction and the impacts on land owners who allowed gas companies access to their land in the US.

The screening will take place at 7.30pm on Tuesday, September 20 at the Burdekin Theatre Loft and is free of charge.

Mackay Conservation Group coordinator Patricia Julien said coal seam gas extraction at the massive scale planned would have extensive impacts on the natural environment, management of farming and grazing lands, and to people's health and quality of life.

"Our greatest concern is that the unconventional coal seam and oil shale fracking gas extraction process produces huge volumes of wastewater which is often salty and contains toxins,'' Ms Julien said.

"The industry is still figuring out how to treat and dispose of this safely. Underground aquifers can also be depleted or drained by this mining," she said.

"While the Queensland Government says it is committed to balancing the interests of both the agriculture and resource sectors with issues like food security, the rhetoric doesn't exactly match the policy."
