Exposure to gas drilling operations is strongly linked to serious health problems in humans, pets, livestock and other animals, a new US study has found.
Australian environmentalists say the study shows the need for caution in opening the country to coal seam gas (CSG) extraction.
University of Massachusetts researchers interviewed 24 US farmers affected by shale gas drilling and found the practice was "strongly implicated" in serious health problems in humans and animals.
In one case, 17 cows died in one hour from respiratory failure after shale gas fracking fluids were accidentally released into an adjacent paddock.
Fracking refers to the controversial method of injecting chemicals, water and sand at high pressures to crack rock and release gas.
