Dr Carolyn Orr is a Consultant Neurologist who trained at Glasgow, Sydney and Rochester Minnesota, and who specialises in neurodegenerative brain disease and young onset dementia, but she also speaks out about air pollution and the related human health issues on behalf of Doctors for the Environment Australia. Air pollution kills over 7 million people per annum on our planet, affecting the entire population from unborn babies through to mature adults. Dr Orr painted a very alarming picture of what is going on here in Australia, and whilst it is not nearly as bad as some places such as India, it is still somewhat dire. She has calculated that on average 76 days of life are lost in Australia per individual, and Dr Orr went into detail about the four major contributors. They are: vehicles; industrial pollution; gas in our homes; and wood smoke. More people die each year from vehicle pollution than from road accidents, and the figure stands at around 1800 p.a. at present. Secondly, industrial pollution such as the burning of fossil fuels plays a big part, and when the statistics are viewed by postcode, WA has 4 of the worst 10 in the country. Thirdly gas in our homes increases the risk of cancer and asthma, and fourthly wood smoke is very toxic – think of prescribed burns, wood heaters, and bushfires! One of the answers is to electrify everything, but at what cost?
