The Australian Story episode on ABC 1 last evening is one that all Tasmanians should watch and note - it is online here: http://www.abc.net.au/austory/. I believe the 2nd part is on next week. The political manoeuvrings in dealing with the highlighted issue of water catchments on the northeast coast of Tasmania have major implications for the health and safety of all who walk and drink the water in plantation catchments. This is not a reflection of one party or another - I live in another state where water issues are something of a contentious issue at the moment as well - but the way that governments of any persuasion pander to the wishes of powerful industry groups, to the apparent detriment of the 'rest of us' and the environment as a whole.

Yes, exactly, but their expert still tried to link it to the spraying several times

Aids is actually been traced back to before the 1950's with some written evidence suggesting it is much older. Same scare tactics used when kangaroos started dying in the 1990s when the population exploded and this was blamed on DDT or any other chemical used on farms when it turned out the same thing happened in the 1930's when the population exploded. It is a natural phenomena as a pathogen largely dormant takes on a more aggressive form or crosses the specie divide. Shonky science based on scare tactics detracts from any legitimate concerns and suggests that there could be another reason, ie, someone not wanting their scenic view compromised or a intrinsic dislike to forestry full stop. When in local government many mundane disagreements suddenly became "hot" when one of the protagonists managed to wangle in a health reason to the argument that subsequent research revealed the reason to be highly dubious. Sorry but I sense a beat up here.
Water quality has been a neglected area and lets face it the worst water quality, most degraded water systems are the ones that run through urban areas and hence the mad push by the State to enforce water quality standards through amalgamating councils sewerage and water supply areas of responsibility. Not going to defend if that is the best way merely pointing out that is the motivation. It never ceases to amaze me that people protesting about water quality are often the same people leading the charge for lower rates and taxes. An activist is an activist I have found.
Any farming or forestry action or urban development will have some effect on the existing natural systems with the challenge being to ensure that the effect is not greater than the benefit of the activity and can be sustained. I am sure if there were two buttons, one labelled eradicate rabbits and the other labelled eradicate trout both would be pushed by people identifying themselves as conservationists. I am equally sure that some people would be happy to push the rabbit one and vigorously fight to stop the trout one been pushed.
Deciding what activity and the level of it is a matter of science and trade-offs. Sure Australia over 200 years ago was a different place and again 100,000 years ago before man kind graced its shores so unless we wish to decamp somewhere else it is up to us to find a balance between employment and environment. Shonky science and beat-ups do not help. In fact the implosion on the science of climate change due to dubious science nowadays means "proper" science and reasons to act are been hidden in the clutter of deception so give excuses to our political overlords to do what they do best, nothing.

Mark,
Did not watch it and I I believe that Televised "beat ups " are just that!! , great for emotive comments but sometimes lacking in real scientific content what did it really achieve![]()

The latest information linked here confirms that the cancers are NOT caused by a virus, http://www.sciencenews.org/view/generic/id/52286/
Quotes -
"Scientists have discovered the true identity of a contagious form of cancer that is killing Tasmanian devils. The cancer, called devil facial tumor disease, stems from cells that normally insulate nerve fibers, a new study shows. Genetic analysis of tumors taken from infected devils in different parts of Tasmania reveals that these insulating cells, known as Schwann cells, became cancerous in a single Tasmanian devil and have since passed to other devils, an international group of researchers reports in the Jan. 1 Science. Previously, scientists had suspected that a virus might be the source of the infection, but the new study confirms that cancer cells themselves are transmitted from devil to devil."
"How the cancerous Schwann cells became contagious is still a mystery, though. “Devils are known to be prone to cancers,” Belov says. “I think it was just some sort of freak of nature that allowed this cancer to be stable and transmitted.”
However the BIG question is to discover why a cancer that has existed in the population for possibly 20 years, suddenly become contagious starting in NE Tasmania in the last decade or so. Perhaps next weeks ABC "Australian Story" will throw some light on this.
