Keeping it real and regional: communication to get Victoria climate-ready

This article first appeared in the December 2016 edition of Eingana, the journal of Environment Education Victoria.


How do you tell a Melbournian what their city’s climate will be like in the year 2070? You could explain that, if the world gets its act together and manages to lower its emissions of greenhouse gases, average temperature will rise by about 1.5°C. If emissions continue to be high, the temperature will rise by about 2.6°C.

Then you could say that extreme temperatures are likely to increase at a similar rate to average temperatures. Melbourne will endure more hot days, those hot days will become significantly hotter, and warm spells will last longer.

If their eyes are yet to glaze over, you could add that winter and spring rainfall are likely to be less than today, and that the frequency and intensity of extreme rainfall events will rise.

But how do you really convey what does all this mean? What will be the impact of this sort of temperature rise and rainfall reduction? There has to be an easier way of quickly communicating this complex, important information.

Thanks to CSIRO and the Bureau of Meteorology, there is. You can just say that in 2070, the climate of Melbourne will be more like the current climate of Adelaide. Most people know that Adelaide is hotter and drier than Melbourne, so they should immediately get a feel for what Melbourne’s climate will be like in future.

That city comparison comes from a communication tool called ‘climate analogues’. You will find it – and much, much more – on the Climate Change in Australia web site. The web site contains all the information underpinning the national climate projections released by the agencies in 2015.

The tool matches projected rainfall and maximum temperature with the current climate experienced in another location for 20-year periods centred on 2030, 2050 and 2090. You can find climate analogues for hundreds of Australian locations.

Regional climate change

The CSIRO and the Bureau of Meteorology projections are the most comprehensive ever prepared for Australia. However, their use at an intra-state/regional scale is limited.

The Victorian Government commissioned CSIRO to prepare regional climate projections for the state. The government were then faced with the challenge of conveying this information – so it informed people about their changing climate, explained the likely impacts of climate change, and described how best to adapt.

The Victorian Government contracted me and colleagues Karen Pearce from Bloom Communication and Rohan Hamden, a climate adaptation specialist, to prepare communication products that met this challenge.

The project represented the perfect opportunity to put into action some of the latest thinking and advice on communicating complex science.

The psychology of communication: Here and how; not gloom and doom

Decades ago, science agencies began employing information officers, communicators, public relations people and the like to pump out the facts. These staff wrote media releases, newspaper features, brochures, pamphlets and books describing scientific, technical and environmental findings.

The approach was based on the ‘empty bucket’ or ‘deficit’ model. It assumes that people have information gaps in their brains ready to be filled with facts, and that if a little fact pushing doesn’t work, then increasing the flow of brochures, newspaper articles, and radio talks will help.

The problem is that the deficit model has limited effectiveness. Often it fails completely, having the opposite effect of what was intended.

Climate change is an example of the failure of the deficit model. Despite massive communication efforts, a considerable proportion of people still do not accept that climate change is caused by human activities. A 2014 CSIRO survey (Leviston et al., 2015) found that 8 per cent of Australians don’t think that climate change is happening, 8 per cent have no idea whether it is happening or not, and 39 per cent of Australians say that it is happening, solely due to natural causes. Brulle et al. (2012) suggest that climate science has little direct influence on public opinion on climate change in the United States.

Propagation of more and more information is not the way to engage people with complex issues like climate change. Social scientists have long realised that inclusion and dialogue are essential.

Dr Sander van der Linden is a Social Psychology lecturer at Cambridge University. In a paper entitled ‘Improving public engagement with climate change: five “best practice” insights from psychological science’, (van der Linden et al., 2015), he provides recommendations on this topic. The five insights apply more widely than climate change.

Paraphrased, they are:

  • our brains value experience over analysis;
  • we are social and mimic peer behaviour;
  • the here and now is more important than something that may (or may not) affect us profoundly in future;
  • we like to win; and
  • human motivation is powerful.

Applying these insights to communication means that we should:

  • highlight personal experiences and local examples;
  • describe effective local action;
  • emphasise local changes;
  • accentuate the positive (for example, reducing emissions equals cleaner air); and
  • seek to build a better tomorrow.

So rather than ineffective messages of gloom and doom, the more effective communication approach relies on familiarity, hope and optimism

Climate-ready Victoria

The Victorian Government commissioned six brochures, covering each of the state’s regions, and an overall state-wide publication. The set, entitled Climate-ready Victoria carry the description: ‘Getting climate-ready involves understanding how climate change is likely to affect you and your region, and working out ways to adapt.’

We sought to develop content that:

  • has a clear, positive, empowering message/narrative;
  • provides a clear regional context in terms of climate, economic and demographic information;
  • highlights regional impacts of a changing climate; and
  • showcases real examples of climate-ready actions that are already under way.

We also catered for the many ways that people interpret information by incorporating:

  • clear, plain English and textual signposts;
  • pictograms and infographics to provide clear visual cues and summaries; and
  • different styles of graphs and tables to convey data.










Presenting technical information in a variety of ways can help people absorb information. The Victorian climate change brochures use a variety of graphics to convey information.


Throughout the process, the content development was refined by feedback from stakeholders and scientists to ensure that the information was accessible, useable and relevant to the particular region, but also that the underlying science was not lost in translation.

The brochures included the climate-related risks for primary production, infrastructure, tourism, health and the community, and the environment. They describe potential impacts on each sector and relevant adaptation measures.

Climate risks for primary production include lower rainfall, more heat days and increased fire weather. Potential impacts are likely to include earlier flowering times, changed distribution of pests and diseases and reduced water security. Adaptation measures could include considering enterprise diversification, different crop varieties and sowing times and regularly accessing long- and medium-range outlooks, as well as short range weather forecasts.

Supporting the brochures are regional data sheets for a range of climate variables, presented annually and by season.

‘The brochures present great information about climate change that is easy to read and understand. They help start the conversation about how the potential impacts of climate change could affect different industries and business, especially for understanding the potential risks and whether these should be considered in budgets. They also provide great references to where to get further information,’ said Sandi Bowles, Sustainability Programs Officer, Port Phillip Region, Department of Environment, Land, Water and Planning.

Ben Craven from Emergency Management Victoria, said ‘The brochures have been a valuable resource, combining all the relevant information into a single, easy to understand source. There’s the right amount of detail to bring people up to speed on the projected impacts of climate change. This information is useful in helping us understand Victoria’s needs for the future.’

2017 AMOS conference: What to expect

This article first appeared in The Bulletin of the Australian Meteorological & Oceanographic Society, vol 3, 2016.


Canberra’s average February maximum temperature is 28 °C. So that sounds just about the perfect time to visit the nation’s capital to converse on climate, opine on oceanography and wonder about the weather.

Each year, the AMOS conference seems to get bigger. The number of abstracts submitted indicates that we can expect to be rubbing shoulders with around 500 colleagues at the 2017 event.

The conference will be at the Australia National University’s Manning Clark Centre, a from 7 to 10 February 2017.

The Monday before the conference, 6 February, will feature workshops on topics as varied as communication, software, and climate projections data, so consider spending a week in the ACT.

The list of high-profile international speakers is headed by David Grimes, World Meteorological Organization President and Canadian Meteorological Service Director. Also present will be Laura Furgione, NOAA Weather Services Deputy Assistant Administrator and US National Weather Service Deputy Director.

Here are just some of the fascinating topics that leap out from the list of accepted abstracts:

  • The impact of the Great Barrier Reef on local climate
  • Improved monitoring and prediction of fire weather
  • Increased population exposure to climate change-driven precipitation extremes
  • Record temperatures set in Australia in recent years to become the norm by 2030
  • Future snowfall probabilities for Alpine Australia
  • Indigenous seasons of north-east Arnhem Land
  • Heatwave forecasts
  • One thousand years of past hydrologic variability
  • Hail and lightning climatology
  • Impacts of 1.5 degree warming on the occurrence of extreme El Nino events
  • Urban heat mitigation strategies to cool Melbourne
  • Marine heatwaves and their drivers
  • The strongest, longest and largest marine extreme events

We know from experience just how much work is involved in organising a large conference, and we can tell you that our Executive Officer, Jeanette Dargaville is doing a superb job of managing tis complex event.

Working closely with Jeanette is the Local Organising Committee of Clem Davis, Mary Voice and Bob Cechet.

Urgent action requires weighing up risks

Adaptation activities need to be informed by the best available science, but sometimes urgent action requires weighing up risks. A lack of information is no excuse for delaying action in an emergency.

This was the case at Port Fairy, 280 km west of Melbourne on the south coast of Victoria. The beach is often flooded, and erosion puts around 200 beach-front homes at risk of being undermined. Additionally, sea-level rise and erosion have exposed rusty metal, glass and asbestos from two decommissioned landfills.


‘The most obvious climate change issue is sea-level rise,’ says Robert Gibson, the Manager of Environment and Regulatory Services at Moyne Shire Council. ‘We’re already looking at properties being inundated and roads blocked off during storm surges, with sizeable rocks being thrown up that require a front-end loader to remove. Sometimes you need to bring a lilo to the beach rather than a towel!’

He says they are fortunate to have the local community conducting monitoring and sharing information, and Council has undertaken remedial action. ‘We’ve done studies on engineering solutions to the loss of beach sand, engineering assessments of the current sea wall, and designs for its upgrading, and started implementing some of these solutions,’ he says.

Robert says research has been fundamental to the decisions being made. ‘Without knowing the limitations of the current sea wall, it would be hard to justify the funding to upgrade it. With scientific information, we know we are doing what’s required for the long-term protection of the houses and assets on the dunes.’

Conversely, he says action to address the exposed tip site has not been as thoroughly researched. ‘It was at crisis point; rubbish was emerging from the dunes, so taking action was necessary with minimal research behind it. We trialled a 125-metre wave energy dissipation structure to mitigate erosion. Within weeks of construction, the structure was tested by a storm. After the storm you could clearly see the structure was the difference between minimal rubbish falling out of the tip, and having a catastrophe.’

Robert says they took a chance, as doing nothing due to insufficient information is not an excuse. ‘You need to weigh up the risk and rewards, and get the job done.’

20 Top Twitter (and social media) tips

These pointers come from Twitter science social media stars ‪@AstroKatie, ‪@EuanRitchie1 and ‪@astroduff who were panellists during an Innovation week event hosted by @miss_toni on 11 November 2016, at the Royal Society in Melbourne.

‪Hash tags: #SciSocialites ‪#innovationwk

  1. Social media panelThe advantage of Twitter is that you can engage with people who would otherwise never engage with you. You can have ‘conversations’, for example with scientists and actors such as Brian Schmidt, Stephen Fry, or Will Anderson.
  2. Twitter is very inclusive. If you are a scientist wanting to ensure your research has impact, you can reach people with particular interests, such as farmers. ‘Making my science matter’ is the motivation. You can also reach journalists and other influencers.
  3. You can use Twitter for communication; advocacy; and highlighting your work, yourself, your field, and your agency.
  4. It’s most important to choose the right hashtags to maximise exposure and impact.
  5. Social media allows researchers to bring science to the public, bypassing pay-walled journals
  6. Warning: Current and prospective employers will check out your social media!
  7. Dealing with trolls – just block them and don’t engage beyond a succinct polite message.
  8. Consider muting people rather than blocking.
  9. Sharing your own perspective can be more effective that trying to change someone’s views directly. Try to remain calm and supply accurate information. People might not agree, but there are lots of examples of people listening and acknowledging the response of others.
  10. Interacting and being multi-dimensional, and responding to people will encourage people to engage with you.
  11. There is software that will send your material out to different social media platforms in one go, such as Buffer (
  12. You never know what a tweet can lead to. A researcher spoke of being concerned about a mooted change to environmental legislation. He tweeted some key researchers, urging action. This was a public discussion and it resulted in a significant research paper.
  13. Commit time to tweet. One panellists said he spent at least 30 minutes each day tweeting.
  14. Social media represents a great opportunity for organisations to engage very swiftly and to respond to issues.
  15. Be aware that social media can be an ‘echo chamber’ where lots of people just self-select those with identical views.
  16. Twitter is probably in decline. Instagram may be rising.
  17. Facebook is more closed than Twitter. It is a good medium for a distinctive community, where you can keep material for perpetuity.
  18. Snapchat is popular especially among younger people; Tumblr is popular among uni students.
  19. Your social media choice will be dictated by you knowing your audience and your communication objectives.
  20. To build your Twitter profile: Follow thought leaders and influencers; always include your twitter handle in presentations; be personal, have a ‘voice’; build trust; tailor your message to the audience.

Book review: ‘Surviving the 21st Century: Humanity’s Ten Great Challenges and How We Can Overcome Them’

Surviving the 21st Century Australia has no better science writer than Julian Cribb. He is knowledgeable, extraordinarily well informed and superbly adept at presenting accurate, fascinating information in a way that just begs to be read.

His latest book is Surviving the 21st Century: Humanity’s Ten Great Challenges and How We Can Overcome Them. The fact that we have survived for 16 years of the century shouldn’t lull us into thinking that the remaining 84 years will be straightforward. I write this review on the day WWF report that ‘worldwide populations of mammals, birds, fish, amphibians and reptiles have plunged by almost 60 per cent since 1970 as human activities overwhelm the environment’.

Each chapter in Surviving the 21st Century considers a great challenge, including mass extinction, resource depletion, weapons of mass destruction, climate change, universal toxicity, food crises, population and urban expansion, pandemic disease, dangerous new technologies, and self-delusion.

It’s easy to describe problems, more difficult to proffer solutions. Cribb does this at each chapter’s conclusion in a section called ‘What we must do’.

Surviving the 21st Century does something that few other publications do: it comprehensively addresses all the main threats to us and to our planet. The holistic approach offers more hope than efforts to tackle problems individually, which can sometimes make matters worse.

Cribb knows intuitively how to convey information vividly and accurately. Writing about frogs, he states, ‘Two in every five of their known species face extinction’. That expression grabs you more than the ’40 per cent’ that most scientists would write.

Years ago, US journalists coined the term ‘Hey Martha’ for stories and news items so amazing that when you hear them, you just have to shout across the room, Hey Martha, listen to this!’. Surviving the 21st Century is full of such examples. They grab your attention and make you think, which is the whole point. Hopefully, sufficient numbers of people thinking will lead to action.

Here’s a ‘Hey Martha’ from the book: What consumes 10 kg of topsoil, 800 litres of fresh water, 1.3 litres of diesel, a third of a gram of pesticide and causes 3.5 kg of carbon dioxide to enter the air? Answer: the last meal you ate. Now multiply that by all the meals you’ve consumed and all the people on Earth. No wonder we have a problem. As Cribb puts it, ‘the human jawbone is among the most destructive of implements on the planet’.

Here’s another sobering anecdote for Martha: ‘Tonight around two hundred thousand more people will sit down to dinner than dined last night.’

You’ll be hard pressed to find a page without a fascinating factoid. Cribb certainly does his research, and knows how to craft that research into unforgettable messages.

What’s his recipe for curbing the impact on planet Earth of our insatiable hunger? Sustainable urban food production using recycled water and organic waste; teaching the next generation to value and respect food; apply a food levy to pay farmers and indigenous peoples to restore and maintain the environment; introduce a ‘Year of Food’, teaching respect, awareness and appreciation of food, in every junior school on the planet. There are many more suggestions on the menu. Each is thought provoking and a number are completely original. It doesn’t matter if you disagree with some of the ideas or think that they may be unfeasible, Cribb has set out a range of options well worth considering. Doing nothing is not one of them.

If you’d like to pursue any of the idea and possible solutions, Surviving the 21st Century includes a detailed list of references.

The ‘sapiens’ in homo sapiens means ‘wise’ in Latin. We can demonstrate wisdom by getting hold of a copy of Surviving the 21st Century and applying some of the recommendations to our own lives. We can recommend the book to others. We can alert our leaders to the book and its contents. We owe this to ourselves and to our planet.



Movin’ on up to cooler climes

Climate change impacts on the natural world are accelerating rapidly.

‘Many plants and animals are proving to be highly sensitive to the changes in climate we have experienced over the last few decades’ says Professor Lesley Hughes from Macquarie University.

Lesley says there are now hundreds, if not thousands of examples of shifts in distributions of plants and animals as they respond to the changing climate. ‘We are also seeing insects emerging earlier, many animals mating earlier, plants flowering earlier, and migrating birds arriving in Australia sooner and leaving later,’ says Lesley. ‘In some cases, the responses of individual species are having significant flow on impacts to ecological communities.’

For example, the long-spined sea urchin (Centrostephanus rodgersii) has expanded its range from coastal NSW to Tasmania, where it has established extremely successfully. As the urchin eats kelp, this shift has had huge impacts on kelp beds, affecting the habitat of many other species, including commercial lobster populations.

Such movements are consistent with responses to the changing climate. You can find out more at

Many Australian species are heading to cooler regions, such as butterflies which have shifted their range 200 kilometres south.

Learning from failure

As part of a major national project on innovation, Scientell has examined the contribution that learning from error and failure can make to innovation and progress. This is part of our work with the Australian Council of Learned Academies (ACOLA) to synthesise a wealth of information into a book on securing Australia’s future. The following is a sad example of failure.

On 29 March 2005, 37-year-old Elaine Bromiley entered a British hospital to undergo routine surgery to clear her sinuses. The mother of two was otherwise healthy.

Problems occurred immediately the anaesthetic was supplied. With no warning, Elaine’s oxygen levels plunged. Her airway was blocked – a most unusual event that happens in fewer than one in 50,000 routine cases of people being given an anaesthetic. The anaesthetist and the surgeon immediately tried to insert a tube into her airway. Additional medical staff quickly arrived to assist, including two recovery nurses, an ear, nose and throat surgeon and another consultant anaesthetist. For 20 minutes, the team desperately attempted to clear her airway.

Sadly, the emergency procedure failed. Elaine was transferred unconscious to the adjacent intensive care unit and died 13 days later.

Elaine’s husband Martin Bromiley was a commercial airline pilot. He knew how his industry would have responded to a similarly catastrophic event. One of the medical team told Martin that ‘maybe when this is investigated something can be learned. But we won’t investigate, not unless you sue or complain.’

‘For me as an airline pilot, that is where everything changed, because to me it is perfectly normal to investigate when something does not happen so you can learn from it, and here we had a situation where somebody was healthy, was going to be made more healthy, and was actually dead. I could not understand why you would not want to learn from it.’

It took some doing, but Martin managed to initiate an independent review of the case.

‘Arguably, it technically was a dream team to deal with this sort of emergency, but what we know happened, if you will excuse the phraseology, was that the situational awareness, the shared mental model of the three consultants, was different. They lost awareness of time; they lost awareness, perhaps more importantly, of the seriousness of the situation; they became fixated – which is not unusual under stress – on intubation to the exclusion of any other options, such as some form of surgical access.

From my background in aviation, I could see very quickly that these were in fact failings in what you refer to as “non-technical skills”: situation awareness, leadership, teamwork, prioritisation, communication, and assertiveness. These same human factors of failings in non-technical skills are the direct cause of 75% of aviation accidents.’

An incision into Elaine’s throat – a tracheotomy – may have saved her life. That it didn’t happen, was not the failings of any individual, but rather the failings of a flawed system.

Today, the findings from the inquest form the basis of training in Australia and elsewhere of healthcare clinicians, particularly those involved in advanced airway management.

The death of Elaine Bromiley was a tragic failure, but it was a failure that people learned from, and one that has improved the way in which emergency operating theatre procedures are conducted.


Is there a doctor on this flight?

Scientell is working with the Australian Council of Learned Academies (ACOLA) to synthesise a wealth of information into a book on securing Australia’s future. As part of this, we have examined the contribution that learning from error and failure can make to innovation and progress. This example demonstrates the way in which the medical profession is learning from the aviation industry’s approach to safety.

Safety is paramount for the aviation industry. Aircraft accidents are infrequent, but when they occur they involve massive losses of life. The exhaustive investigations that follow crashes have produced extensive literature into their causes, and new policies and regulations to improve safety. Research by the National Aeronautics and Space Administration (NASA) into aviation accidents has found that 70 per cent involve human error.

Writing in the British Medical Journal, Robert L Helmreich, professor of psychology at the University of Texas, states, ‘Error results from physiological and psychological limitations of humans. Causes of error include fatigue, workload, and fear as well as cognitive overload, poor interpersonal communications, imperfect information processing, and flawed decision making.’

‘In both aviation and medicine, teamwork is required, and team error can be defined as action or inaction leading to deviation from team or organisational intentions. Aviation increasingly uses error management strategies to improve safety. Error management is based on understanding the nature and extent of error, changing the conditions that induce error, determining behaviours that prevent or mitigate error, and training personnel in their use.’

Diagnosis should include data from confidential incident reporting systems and surveys, systematic observations of team performance, and details of adverse events and near misses.

It is now commonplace for medical doctors to learn from the approach to error and failure that has been refined and systematically adopted in aviation.

The error management approach that Helmreich advocates includes:

  • Dealing with latent factors that have been detected, changing the organisational and professional cultures, providing clear performance standards, and adopting a non-punitive approach to error (but not to violations of safety procedures);
  • Providing formal training in teamwork, the nature of error, and in limitations of human performance;
  • Providing feedback and reinforcement on both interpersonal and technical performance; and
  • Making error management an ongoing organisational commitment through recurrent training and data collection.

As physician Dr Lucian Leape, a physician and professor at Harvard School of Public Health, states:

‘The most fundamental change that will be needed if hospitals are to make meaningful progress in error reduction is a cultural one. Physicians and nurses need to accept the notion that error is an inevitable condition, even among the conscientious professionals with high standards. Errors must be accepted as evidence of system flaws not character flaws.’ [1]

Robot servants: lending a metal hand

Robots are ideally placed to help with future housework, since they can perform repetitive tasks
without becoming bored. Since the 1927 film Metropolis, robots have lent a helping hand to humans in many science fiction movies, such as Star Wars, Wall-E and Elysium. The television cartoon series The Jetsons featured Rosie the robot maid.

Could robots soon take over the cleaning? Or, will they take over the world?

Real robots

Metal humans have featured in stories as old as Greek mythology. In 1818, Mary Shelley published her story of Frankenstein, the scientist who created an artificial human. A couple of years later, a science fiction play by Karel Capek called R.U.R. (Rossum’s Universal Robots) first used the word ‘robot’. The term was based on the Czech word ‘robota’, which means forced labour – so developing them in the real world as servants seems appropriate.

For more than 30 years, robots have performed repetitive tasks in car assembly lines. A typical
car factory today uses hundreds of robots. The military has used robots that can independently fly, refuel and select targets to attack.

Honda’s ASIMO (Advanced Step in Innovative MObility) robot, first unveiled in the year 2000, looks like a short astronaut. It can climb stairs, run, kick a soccer ball, dance, carry a tray of food, and knows to return to a power point if its batteries are running low.

However, the robots found in the home today are only vacuum cleaners or toys. A robot vacuum cleaner shaped like a large discus became available in the 2000s, and more than 10 million have been sold.

Robots rule

If robots can communicate with each other, teach themselves new things and learn without human help, could they team up and harm the human race? Not according to the famous science fiction writer Isaac Asimov, who came up with the three laws of robotics. These are: (1) a robot may not injure a human being or, through inaction, allow a human being to come to harm; (2) a robot must obey the orders given to it by human beings, except where such orders would conflict with the first law; and (3) a robot must protect its own existence as long as such protection does not conflict with the first or second law.

A scary idea is the possibility of computers with artificial intelligence becoming smarter than humans. This point in the future is called the ‘singularity’. After this point, it is impossible to predict or understand what such ‘intelligent’ beings would do. Perhaps they would compete with us for resources, or decide we were too harmful for the environment and exterminate us.

But in the meantime, those robotic vacuum cleaners don’t look too dangerous.

Faster food: 3D print your dinner

You arrive home from school, hungry for a snack. You feel like something different; not the usual food your fridge and pantry automatically order based on what you normally eat. So you search for a treat on the internet, find one that looks good, and press print. Your 3D printer creates a ready-to-eat copy. Meanwhile, your parents are in the kitchen printing dinner. Welcome to the high-speed, low-waste, good-health world of future food.


3D printers were invented in the 1980s. Rather than print an image using a layer of ink, they can print an object using layers of plastic or metal. Through the 1990s and 2000s, 3D printing helped in the design of new products and was used to make one-off prototypes of objects. Today, 3D printers are cheaper and more widely available. They are already used in mass production of items in factories and to print objects at home.

It is early days for 3D food printing. You can buy a 3D chocolate printer, which uses melted chocolate to print chocolate pictures and objects. Similarly, a sugar-based 3D printer can print sweets in creative shapes. A 3D pasta printer can print ravioli if you top up its ‘printer cartridge’ with dough and fi lling. Other 3D printers can mix together ingredients, or use pureed vegetables, to print food such as quiche, hamburger patties or corn chips. But 3D food printers are slow, depositing one thin layer at a time. And they can’t create food out of nothing: the food shapes are made from ingredients that were already edible before being transformed by the printer.
