About two years later he was forced to use a ventilator to stay alive. He died soon after.He had been planning on moving to be with family to the Sunshine Coast.Mrs Thomas relayed her personal story in emails to all the Sunshine Coast councillors.“The silica dust, when inhaled, works like small blades scarring the lungs which, over time, become stiffened making it difficult to breathe,” she wrote.“Exposure levels can be mild and may not show for 20 - 30 or more years, but can cause long term irreversible effect. “So why on earth would we consider putting a sand mine near residential areas and schools!?”She told them how her step-father and mother Janis made the difficult decision together to turn off the machine that was keeping him alive.“This was one of the saddest days of my life,” she wrote the councillors.“Why, even if there is only a small risk of ongoing dust exposure, would we consider putting a sand mine so close to residential areas and schools? “PLEASE reject the application for a sand mine in this area, the potential negative impact to people's lives far outweighs the financial gain by the company proposing the development.”Most of the councillors replied, thanking her for her letter, extending their condolences, and assuring they would keep her experiences in  mind during the sand mine assessment process. The firm proposing the mine, Maroochydore Sands, has urged interested community members to review the company’s website for details about the project. www.maroochydoresands.com
