“It just seems that they have declared war on the planet.” Pete Lane
DePAw lit up a large forest block ( Kearney block, about 64 sq km) on April 20th and must take responsibility for the health impacts thisis, and will have, on hundreds of residents. Kearney block is about 2 km southwest of Nannup. Unfortunately many such blocks of similar size, set aside by all govts since 1920 as high conservation value, were logged in 2012. Should these all be burnt this autumn there will be implications for human health (1) and climate change will accelerate. Burning forests produce more hazardous smoke than burning coal.(2)
It turns out that the very weather conditions which favor safe burning conditions in terms of homes and property damage, maximizes human health effects. Virtually no wind and dew every evening has ensured the residents sat in carcinogenic smoke every night for more than a week and counting. Health impacts of exposures to these gases and some of the other wood smoke constituents (e.g., benzene) are well characterized in thousands of publications. The Polycyclic aromatics released in particular are not only irritants, but mutagenic, carcinogenic, and neurotoxic.
As a nearby resident I was not warned of this controlled burn. Were people with pre-existing heart or lung conditions warned? Data suggests there was an increase in out-of-hospital cardiac arrests in Melbourne during the 2006-2007 bushfire season in Victoria, many hundreds of kms away from where the forest was burning in the Victorian Alps. (3)
The conventional thinking has been that controlled burns are needed to reduce debris under the forested areas to reduce the intensity of a fire. Recent fires have showed controlled burning has little to no effect in slowing, reducing and stopping forest fires. Recent Northcliffe fires are a case in point. A lightening strike in a prescribe burnt area started the fire. The fire quickly spread .Fire Chiefs were expecting that when the fire reached a certain area that had been prescribe burnt 5 years earlier, it would slow down and be containable. It did not slow down.
Controlled burns don’t stop wildfires but they do cause human and native health and crop damage. So why are we burning again ? There is little reason to continue putting the health and welfare of local residents, animals and agricultural systems (grapes etc) at risk with annual controlled burns. With residents ill, crops damaged, health damaged, lifestyle damaged, the sentiment that wood smoke ,(being a natural substance) must be benign is still sometimes heard. It is now well established, however, that wood-burning stoves and fireplaces as well as wild land and agricultural fires emit significant quantities of known health-damaging pollutants, including several carcinogenic compounds (e.g., polycyclic aromatic hydrocarbons, benzene, aldehydes, respirable particulate matter, carbon monoxide [CO], nitrogen oxides [NOx], and other free radicals) (4)The range of potentially toxic gases and other substances of concern include atmospheric mercury, ozone precursors and volatile organic compounds.
When I rang the hospital to enquire about a respirator. the nurse said I should go for a drive to some fresh air. I rang the department DePAw duty offficer and asked him “where is there some fresh air? “ He was a nice young man who said he couldn’t help me. He said there were fires everywhere and not just his department’s fires burning, but farmers and householders. Everyone is keen to “reduce fire risk” to their property….what about risks to something more important , our health?
Does the government have the right or legal freedom to cause us harm?
Could we not plant fire retardant trees shrubs and ground covers as fire breaks? Growing these shelter belts would ameliorate climate change which leads to increase in wild fire intensity and frequency. South Hampton homestead owner Jeff Pow told me some of his animals sheltered behind a Robinia hedge to survive. Oaks also provided shelter for fire fighters in the blaze, while other tree species exploded.
Eucalyptus forest burns. Our native forestshave been artificially created by human intervention (fire) in recent history. We humans should not live in the forest, or we should protect our homes with fire retardant plants and intelligent design rather than controlled burns.
Land developers have an obligation here to develop already cleared land , not settle people amongst the trees.
Solution! We can reduce property loss from bushfire and other catastrophic results of global climate change by planting buffer zones of flame retardant vegetation.
In other words, we fight fire not with fire but with plants. Logged forest areas should be left un-burnt to decompose into humus ( it doesn’t burn, and facilitates the growth of plants which in turn create lush conditions )
We can make soak up carbon from the air by making compost, and again by planting the many flame retardant species available (5) (eg Robinia, succulents) to shelter our homes and livestock from fires.

[ Smoke travels] and “ is known to irritate the respiratory system, but evidence suggests it’s the particles that damage people’s health, says Dr Fay Johnston from Menzies Research Institute in Tasmania. Dr Dennekamp adds it’s the very small particles – those with an aerodynamic diameter smaller than 2.5 micrometres – that are likely to cause the most significant concern”.”And in particular the very small particles that can penetrate deep into the lungs,” she says.“Symptoms caused by these particles can continue for days after they are inhaled.”
WHO’s International Agency for Research on Cancer(IARC) scientist Christopher Wild says”We now know that outdoor air pollution is not only a major risk to health in general, but also a leading environmental cause of cancer deaths.”
NSW Air Quality Monitoring agency says:”An air quality alert may be raised when pollutant concentrations reach levels which exceed national air quality standards for gaseous pollutants (ozone, carbon monoxide, nitrogen dioxide and sulfur dioxide), fine particles …. During an air quality alert, people sensitive to the effects of air pollution are likely to feel its impacts (POOR and VERY POOR categories) or during extreme episodes of air pollution such as during prolonged bushfires (HAZARDOUS category) which can affect everyone’s health” www.environment.nsw.gov.au
5) a small sample of suitable flame retardant species : salt bush,Coprosma, elms, oaks, willow, guavas, tagasaste, paulownia, hydrangea, geranium, comfrey, sweet potatoe, alfalfa tree tomatoe etc. For a list of native plants that will not burn in the face of continuing flame, see this website http://www.apsvic.org.au/plant_fire_resistant.html. People can test more plants by throwing a small branchlet into a fire and watching how it behaves.
This is all just so crazy, but we can revolutionize the thinking:
