Expert prognosis for the planet – we’re on track for a ghastly future

An international group of 17 leading scientists have produced a comprehensive yet concise
assessment of the state of civilization, warning that the outlook is more dire and dangerous than is
generally understood.
A loss of biodiversity and accelerating climate change in the coming decades coupled with ignorance
and inaction is threatening the survival of all species, including our very own, according to the
experts from institutions including Stanford University, UCLA, and Flinders University.
The researchers state that world leaders need a ‘cold shower’ regarding the state of our
environment, both to plan and act to avoid a ghastly future.
Lead author Professor Corey Bradshaw of Flinders University in Australia says he and his colleagues
have summarised the state of the natural world in stark form to help clarify the gravity of the human
“Humanity is causing a rapid loss of biodiversity and, with it, Earth’s ability to support
complex life. But the mainstream is having difficulty grasping the magnitude of this loss,
despite the steady erosion of the fabric of human civilization” Professor Bradshaw says.
“In fact, the scale of the threats to the biosphere and all its lifeforms is so great that it is difficult to
grasp for even well-informed experts.
“The problem is compounded by ignorance and short-term self-interest, with the pursuit of wealth
and political interests stymying the action that is crucial for survival” he says.
Professor Paul Ehrlich of Stanford University says that no political or economic system, or leadership,
is prepared to handle the predicted disasters, or even capable of such action.
“Stopping biodiversity loss is nowhere close to the top of any country’s priorities, trailing far
behind other concerns such as employment, healthcare, economic growth, or currency
“While it is positive news that President-elect Biden intends to reengage the US in Paris Climate
accord within his first 100 days of office, it is a minuscule gesture given the scale of the challenge.
“Humanity is running an ecological Ponzi scheme in which society robs nature and future
generations to pay for short-term economic enhancement today”.
“Most economies operate on the basis that counteraction now is too costly to be politically
palatable. Combined with disinformation campaigns to protect short-term profits it is doubtful that
the scale of changes we need will be made in time” Professor Ehrlich says.
Professor Dan Blumstein from UCLA says the scientists are choosing to speak boldly and fearlessly
because life literally depends on it.
“What we are saying might not be popular, and indeed is frightening. But we need to be candid,
accurate, and honest if humanity is to understand the enormity of the challenges we face in creating
a sustainable future.
“Without political will backed by tangible action that scales to the enormity of the problems facing
us, the added stresses to human health, wealth, and well-being will perversely diminish our political
capacity to mitigate the erosion of the Earth’s life-support system upon which we all depend.
“Human population growth and consumption continues to escalate, and we’re still more focused on
expanding human enterprise than we are on devising and implementing solutions to critical issues
such as biodiversity loss. By the time we fully comprehend the impact of ecological deterioration, it
will be too late.
“Without fully appreciating and broadcasting the scale of the problems and the enormity of the
solutions required, society will fail to achieve even modest sustainability goals, and catastrophe will
surely follow” Professor Blumstein concludes.

The experts say their ‘perspective’ paper, which cites more than 150 studies, seeks to outline clearly
and unambiguously the likely future trends in biodiversity decline, mass extinction, climate
disruption, planetary toxification, all tied to human consumption and population growth to
demonstrate the near certainty that these problems will worsen over the coming decades, with
negative impacts for centuries to come. It also explains the impact of political impotence and the
ineffectiveness of current and planned actions to address the ominous scale of environmental
