Olivia Newton-John has condemned the Australian mining industry for contributing to the country's environmental issues.
The Grease star, who also serves as the United Nation's Goodwill Ambassador for the Environment, recently lashed out against industry bosses in an open opinion piece for The Sunday Age publication, in which she detailed her concerns about "fracking" - a controversial method of extracting natural gas from below the Earth's surface.
She wrote, "As a long-time advocate for the environment, I am greatly concerned about the continued health of Australia and its people. That is why I am horrified to learn of the extensive plans for coal seam gas and shale gas exploration here. Until recently, I was unaware of the hidden dangers lurking in this so-called clean natural gas exploration...
"In America, some of the chemicals used in these operations are suspected to be cancer-causing agents. There have been reports of serious health and environmental damage from these mining practices...
"We should be demanding our politicians call a halt to coal seam mining and fracking until we know what harm these chemicals will do to our water, our soil, the air we breathe, our animals, our trees, our rivers, and our food chain for generations to come."
Newton-John isn't the only star to voice her concern about the issue - Australian actress Cate Blanchett spoke out against the practice earlier this year (11).
