ABC Radio 936 18 September 2017 Science and the Social Contract [MP3, 9784.41 KB]
On October 6th at 4pm the book “Enhancing Science Impact: bridging research, policy and practice” by UTAS researchers Peat Leith and Marcus Harward with colleagues Kevin O’Toole and Brian Coffee will be launched at IMAS, Castray Esplanade Hobart. Its subject is renegotiating the contract between science and society. The original contract between science and society involved the production of reliable knowledge with the emphasis on predictability and reproducibility: science makes discoveries and delivers them to decision-makers. Then around the middle of last century something went wrong. We needed science to understand why technology was having unanticipated and harmful consequences (think Silent Spring, Bophal and 3 Mile Island). The original contract breaks down when the facts are uncertain, the values are in dispute and the stakes are high. The new contract demands production of socially robust knowledge (“its very clever but how do you know we want it/we need it/it won’t kill us?”)
ABC Radio 936 22 May 2017 Why is science under fire? [MP3, 7109.72 KB]
On the 22th of April this year in 500 towns and cities around the world, people turned out on the streets to march for science. While this event was triggered by recent changes in the US administration, challenges to the role and legitimacy of science are not new. Think of Galileo, but we don't have to go back that far to find examples. A hundred years ago a prominent Australian scientist warned his colleagues that many people viewed science as “… a threat to society both religious and secular.” To understand why, we need to go back to the four ‘ways of knowing’ – intuition, revelation, observation and reason – and consider how their influence has changed over time.
ABC Radio 936 10 April 2017 The Red Queen dilemma - can we run fast enough to stay in the same place? [MP3, 4396.03 KB]
Two recent studies by Australian scientists raise questions about the capacity of humans to adapt to a changing world. Prof. Greta Pecl from UTAS led a study that illustrates how the movement of plants and animals in response to climate change is already affecting humans, from coffee drinkers to reindeer hunters and sparkling wine to mosquitos. They showed that plants and animals are moving an average 17km per decade away from the poles on land and 78 km in the oceans. In the second study, Prof. Allan Cooper and his group at Adelaide University used mitochondrial DNA in hair samples collected from Aboriginal people between 1920-70 to work out that their most recent common ancestor lived nearly 48,000 years ago. The implication is that the first Australians arrived 50,000 years ago, made their way rapidly around the coast in two waves east and west, and once a group decided to settle in a particular place they stayed put for the long haul, weathering 10 degree fluctuations in climate from the glacial maximum to recent times. So will science, technology and trade give us sufficient flexibility to stay put and adapt, or will there be an increase in climate change refugees, following food, water and other resources as they move in response to climate change?
ABC Radio 936 27 February 2017 What Mark Zuckerberg and Bill Gates could learn from Australia’s rabbits [MP3, 7688.71 KB] The ambition of the tech giants behind Facebook and Microsoft to cure, prevent or manage all diseases in our lifetime raises questions about methods and ethics. On methods, even the smartest biotechnology such as gene editing has to survive the source of biological innovation, genetic variation and natural selection, as each new treatment puts pressure on populations to come up with new forms of resistance in the same way Australia’s rabbits have bounced back from two rounds of biological warfare. The ethical questions are focusing on heart disease and neurological diseases and cancer, chronic diseases of the developed world, rather than those of the developing world where 90% of preventable deaths occur and retaining exclusive rights to commercialise discoveries. These two features raise the prospect suggested by historian Yuval Harari that the outcome will be to upgrade the healthy rather than cure the sick.
ABC Radio 936 28 November 2016 Three books to ease the worried well [MP3, 8714.69 KB]
The Idea of Decline in Western History by Arthur Herman reviews the idea that decline is inevitable, that in the deep past there was a Golden Age when the world was perfect and it’s all about to end. The Better Angels of Our Nature by Stephen Pinker tells the story of the centuries long, relentless decline in violence throughout human history brought about by the emergence of the state, to which citizens agreed to ‘surrender the satisfactions of vengeance for impartial law’ and 'gentle commerce', the mutual benefits of trade.Landscape and Memory by Simon Schama puts the case that landscape is a form of human expression in the same way that poetry, prose and painting are forms of expression. As humans have shaped landscapes to suit our needs they become part of our cultural memory. In Wendell Berry’s words the European new arrivals in North America ‘…came with visions of former places and not the sight to see where they were. They did not know what they were doing because they did not know what they were undoing.’ So too it took 200 years before Bill Gammage could write The Biggest Estate on Earth about Aboriginal fire shaping this continent and Bruce Pascoe could write Dark Emu about Aboriginal agriculture.

ABC Radio 936 5 September 2016 The cabin that changed the world [MP3, 6767.61 KB]
In Wisconsin there is a cabin that changed the world, or at least how people think about it. Professor Ted Lefroy returns from sabbatical with a book by a 90 year old university professor still teaching. Estella Leopold, daughter of Aldo Leopold the author of ‘A Sand County Almanac’, has written her account of life in the Wisconsin shack that shaped her father’s thinking about environmental ethics. Ted explains the key ideas in these two books and what it means to ‘think like a mountain’.
ABC Radio 936 16 November 2015 Collapse-porn vs progress [MP3, 6983.29 KB]
Collapse-porn, apocalyptica and eco-rapture are labels UK science writer Leigh Phillips has applied to an expanding genre of environmental writing that views ecological and social collapse as variously inevitable and desirable. In his new book "Austerity ecology and the collapse-porn addicts: A defence of growth, progress, industry and stuff" Phillips argues that 'Modernity is not the cause of our ecological woes. Only through a deepening of our modernity can we save the planet.'
ABC Radio 936 19 October 2015 'We've been invaded, but does it really matter?' [MP3, 7007.2 KB]The Olive Green Australia Policy, the environmental equivalent of the White Australia policy, has long dominated the environmental debate arguing that we need to shoot, spray, dig or trap any animal or plant that wasn't here in 1788. But can we really freeze a continent in time. Is everything exotic an environmental disaster?
ABC Radio 936 21 September 2015 'Putting a price on nature' [MP3, 7383.71 KB]Can we put a price on nature? The University of Tasmania's Centre for Environment hosted a screening of the documentary 'Banking Nature' in the Stanley Burbury Theatre on Monday 21 September as part of the Environmental Film Festival and a panel of two economists and an environmental scientist explored pros and cons of biodiversity credits, offsets and bio-banking.
ABC Radio 936 17 August 2015, Ted Lefroy: 'Why does science sometimes get things wrong?' [MP3, 6039 KB]
There are 1.4 million scientific papers published every year. Around 3,000 of these (0.2%) are withdrawn due to either genuine mistakes or more rarely fraud. But the bigger reasons why, with hindsight, science occasionally gets things wrong are bias within society against different people or ideas, and unforeseen and unintended consequences.
ABC Radio 936 20 July 2015, Ted Lefroy: 'The war on cats' [MP3, 7524.09 KB]
On Thursday 16 July, Greg Hunt the Federal Environment Minister launched the Australian Governments Threatened Species Strategy at Melbourne Zoo which officially declares war on feral cats. http://www.environment.gov.au/biodiversity/threatened/commissioner/threatened-species-summit But with millions of much loved domestic cats, plus stray cats in towns and cities, is this realistic?
ABC Radio 936 1 June 2015, Ted Lefroy: 'The wolves of Yellowstone' [MP3, 7300.2 KB]
Act 1. 'Playing God in Yellowstone' by Alston Chase published in 1987, tells the story of how humans trashed America's first national park by getting rid of the wolves and letting the elk and deer to eat everything.
Act 2. 'How wolves change rivers' TED talk by George Monbiot on how re-introducing the wolves made everything better – the grass, the trees, the beavers and the rivers.
Act 3. 'Rethinking predators: legend of the wolf' by Emma Marris, on how it's not just top down control of elk and deer by predators, or bottom up control by trees and grass, but 1) a mixture of both and 2) the environment has changed so much in the meantime from lack of predators, drought, fire and most likely climate change that things won't ever go back to how they were in 1872 when the park was declared or 1926 when wolves removed.
ABC Radio 936 11 May 2015, Ted Lefroy: 'Eco-modernism' [MP3, 6405.33 KB]
On April 15, the 'Eco-modernist Manifesto' was released by a group led from the Breakthrough Institute in Washington. This 32 page document argues that economic development is essential to protect the environment, and in doing so divides the world of green politics into 'optimistic pragmatists' on one side and 'pessimistic purists' on the other. Will divide and conquer work?
ABC Radio 936 6 April 2015, Ted Lefroy: 'Gaia' [mp3 6MB] Is Gaia science? Is the Earth and all its inhabitants one thinking, breathing super organism set to reject humanity if it steps out of line, or is Gaia a romantic notion recycled from ancient myths?
ABC Radio 936 2 March 2015, Ted Lefroy: 'Is Evolution Progressive?' [mp3 12MB] A recent article in The Conversation by Simon Tierney: What blind beetles can teach us about evolution describes the discovery of nearly 100 different species of blind and flightless water beetles found in isolated aquifers deep under the Western Australian desert. Each aquifer is home to between one and three separate species, all related to diving beetles found on the surface from which they have been isolated for 5 to 10 million years. Researchers are excited by the find because it enables them to study the genetic mechanism by which species evolve, but this discovery also raises larger questions about progress and direction in evolution.
ABC Radio 936 2 February 2015, Ted Lefroy: 'What is Natural?' [mp3 9MB] A recent paper in the journal Nature called for a truce in the debate about the aims of nature conservation. The debate is between intrinsic value (that nature should be protected for its own sake) and instrumental value (that we need to save nature to save ourselves). Calling for a truce raises as many questions as it answers.
ABC Radio 936 1 December 2014, Ted Lefroy: 'When is the Science Good Enough?' [mp3 10MB] Daniel Sarewitz from Arizona State University has studied a number of complex social problems such as immunisation, literacy and climate change to find out why science and technology has been successful in finding solutions to some problems, but not others. His conclusions explain why some problems seem to be intractable despite the amount of money thrown at them.
ABC Radio 936 10 November 2014, Ted Lefroy: 'Seeds of Salvation' [mp3 5 MB] You've heard Peter Cundall talk about 'no-dig potatoes' on Gardening Australia. This is no-plough farming. Not just minimal tillage, no tillage. No soil disturbance what so ever. Harvesting grain from perennial relatives of wheat, barley, rye, sorghum, rice, and sunflowers has been the research goal of The Land Institute in Salina, Kansas USA for the last 38 years. So far they have released 'Kernza', a perennial relative of wheat.
ABC Radio 936 1 September 2014, Ted Lefroy: 'The balance of nature' [mp3 6MB] There is not now, never has been, and never will be balance in nature. Why? Because we live on a dynamic planet in a changing universe. Charles Darwin's big idea after his Voyage on the Beagle was that the Earth changes, and life adapts. When he landed at Plymouth after five years at sea he in turn changed forever the way we view life on Earth, but the idea of balance remains appealing and very resistant to change.
ABC Radio 936 4 August 2014, Ted Lefroy: 'The Survival of the Fittest' [mp3 9MB]. Charles Darwin never said survival of the fittest. The term was coined by Herbert Spencer, five years after 'Origin of the Species', and what Spencer meant was not physically fit but fit in the sense of most suited or fit for purpose. Fit as in jigsaw, not fit as in gym. In biology, fitness means reproductive fitness or evolutionary success, the ability of an organism to pass on its genes. The term survival of the fittest has been misused ever since Spencer first came up with it to support the concept of 'might is right', that competitive economic and social behaviour is justified on the basis that what is found in nature is good.
ABC Radio 936 14 July 2014, Ted Lefroy: 'The Tragedy of the Commons' [ mp3 4.96 MB] by Garret Hardin is the most requested paper ever published in the prestigious journal Science. Written in 1969, it argues that any natural resource held in common by a group of people such as fisheries, forests or grazing lands will inevitably end up being over exploited. In 2009, Eleanor Ostrom was awarded a Nobel Prize for showing that this is not necessarily true. How she did it is an interesting story that is providing inspiration for a modest experiment in Tasmania.
ABC Radio 936 2 June 2014, Ted Lefroy: 'Why societies collapse?' [mp3 10.9 MB] Two books on the reason societies have collapsed in the past, one by a historian and one by an ecologist, arrive at different conclusions that may have lessons for us. One puts it down to trashing the environment, the other comes to a far more interesting and subtle conclusion. "The Collapse of Complex Societies" by Joseph Tainter published in 1988 and "Collapse: how societies choose to fail or survive" by Jared Diamond from 2005. (Discuss).
ABC Radio 936 7 April 2014, Ted Lefroy: 'Peak baby' [mp3 5.59 MB] Behind the latest IPCC report is information of human demographics that give us grounds for optimism about the impact of human activity on the planet and the fate of our species.
ABC Radio 936 10 March 2014, Ted Lefroy: 'Modelling bushfires' [mp3 8.98 MB] The story of the Dunalley and Gretna fires, how the Tasmanian Fire Service made appropriate use of the Phoenix fire model, and why the criticism from the committee of inquiry was unjustified.
