Government fails to support dying at home in Northern Rivers

Approaching the subject of dying is always tricky, often awkward, and never easy. But when you are faced with caring for someone at the end of their life, it helps if you can find support from people who have already navigated the path.

Around 5500 great white sharks are lurking in the waters off Australia’s east coast, new research has revealed.

For the first time, the CSIRO has been able to put a number on the size of the white shark population using world-first genetic analysis.

It estimates there are about 750 adults in waters east off Victoria’s southern coast, up to central Queensland and across to New Zealand.
Taking juvenile sharks into account, researchers believe the total east coast population sits at 5460 – but could be as high as 12,800.
It’s estimated another 1460 adult white sharks live off Australia’s south-western coast, but a total calculation is yet to be made.
Until now, it was difficult to gather information about adult white sharks because they are hard to sample.
But breakthrough genetic and statistical methods means scientists can estimate shark numbers without having to catch or even see them, the CSIRO said in a statement on Friday.

”Now that we have a starting point, we can repeat the exercise over time and build a total population trend, to see whether the numbers are going up or down,” the research paper’s lead author, Richard Hillary, said.

”This is crucial to developing effective policy outcomes that balance the sometimes conflicting aims of conservation initiatives and human-shark interaction risk management.”

  1. Low or no impact research. This is a great example for all science. Loving all beings & respecting the rights of all beings no mater what skin they’re in is part of ‘growing up’.
    Living harmoniously with nature by now, should absolutely be a personal responsibility & a given.

    Having access to funding is an important contributor with low & no impact research, as part of ‘good & responsible tenancy’ of this country & the planet.

    Maintaining a high level of consciousness to ensure the flourishing future of this beautiful garden planet we call Earth, all species is absolutely our responsibility.

    Japan needs to take a lesson or 50 from these guys. So do policitians & all people alike.

    Home here on Earth is a privelage not a right.
    Honor the gift by honouring all of the animal children of ocean, sky & sea. It is their planet. It is their home.

    Great job CSIRO

    Thanks & blessings
