Rau arrogant and dismissive; O'Leary factual and well reasoned
John Rau's arrogance and disdain for people who disagree with him was clear to see in his article "Population growth debate must expand" (The Advertiser 16/4/13). Mr. Rau attacks Kevin O'Leary's articles for your paper as being based not on facts but merely on opinion. I have read many of Mr. O'Leary's articles and they appear to be based on sound facts and sound reasoning.
Mr. Rau has dismissed concerns that housing people in multi-storey flats on major arterial roads with significant air pollution contributes to disease and health problems. I understand that there is solid international and Australian research which attests to these negative health impacts. In a recent report in the Advertiser, the Australian Medical Association claimed that more people die in Australia from air pollution than from motor vehicle accidents.
