Can you save the planet and have some fun along the way? Aimed at the teacher who updates students on the latest climate change negotiations, the conservationist who works to protect endangered species, the office manager who buys fair-trade coffee, or the city counselor who lobbies for cycle lanes, this book is a guide for everyone who is trying to create a more sustainable planet. Based on the latest psychological research, Niki Harré shows which strategies work (drawing on positive emotions, role modeling, and social identity), which don't, and why. The book ends with a self-help guide for sustainability advocates that outlines how we can work for change at the personal, group, and civic level. This edition is fully revised and updated with new material on hope, sadness, worldview and climate change, behavioral contagion, moral foundations, and more. The book is now accompanied by a free online manual with exercises to illustrate the key concepts and apply them to real world sustainability issues.

Chapter One

Positive Emotions and Flow: Encouraging Creativity and Commitment

Positive experiences are an important way to inspire and motivate people, as they attract us towards the activity or message being promoted. Think about it: if an issue, person or event makes you feel good, you want more. People are happiness seekers – we are attracted to that which induces positive feelings like moths to a flame. Furthermore, positive moods bring out important personal qualities that are essential to social progress. This chapter is about how positive emotions and ‘flow’ states – states in which people feel particularly alive and engaged – can contribute to building sustainability.

The secret of positive emotions

Beginning this chapter are two very different passages, both of which are designed to persuade a reader that our current way of life needs to change. I’ve included these to give you a feel for the emotional effects of positive and negative communications. To get the most out of the passages, read them slowly, and as you read, reflect on how you feel. Next, think about or list the actions you wish to take, given your emotional response to the material. Read and reflect on the first passage and the actions it inspires before moving on to the second one.

Passage One

‘The Earth is about to catch a morbid fever that may last as long as 100,000 years’ – James Lovelock (2006)⁸

Imagine a young policewoman delighted in the fulfilment of her vocation; then imagine her having to tell a family whose child had strayed that he had been found dead, murdered in a nearby wood. Or think of a young physician newly appointed who has to tell you that the biopsy revealed invasion by an aggressive metastasising tumour . . . Gaia has made me a planetary physician and I take my profession seriously, and now I, too, have to bring bad news.

The climate centres around the world, which are the equivalent of the pathology lab of a hospital, have reported the Earth’s physical condition, and the climate specialists see it as seriously ill, and soon to pass into a morbid fever that may last as long as 100,000 years. I have to tell you, as members of the Earth’s family and an intimate part of it, that you and especially civilisation are in grave danger . . . as the century progresses, the temperature will rise 8 degrees centigrade in temperate regions and 5 degrees in the tropics . . . We are in a fool’s climate, accidentally kept cool by smoke, and before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.

By failing to see that the Earth regulates its climate and composition, we have blundered into trying to do it ourselves, acting as if we were in charge. By doing this, we condemn ourselves to the worst form of slavery. If we chose to be the stewards of the Earth, then we are responsible for keeping the atmosphere, the ocean and the land surface right for life. A task we would soon find impossible – and something before we treated Gaia so badly, she had freely done for us.

So what should we do? First, we have to keep in mind the awesome pace of change and realise how little time is left to act; and then each community and nation must find the best use of the resources they have to sustain civilisation for as long as they can. Civilisation is energy-intensive and we cannot turn it off without crashing, so we need the security of a powered descent . . .

We could grow enough to feed ourselves on the diet of the Second World War, but the notion that there is land to spare to grow biofuels, or be the site of wind farms, is ludicrous. We will do our best to survive, but sadly I cannot see the United States or the emerging economies of China and India cutting back in time, and they are the main source of emissions. The worst will happen and survivors will have to adapt to a hell of a climate.

Passage Two

‘Urban New Zealand in 2020 – An organic society’ – Holger Kahl (2007)⁹

You are pedalling back from work with the other seven passengers sharing the solar-assisted Octocycle. You are cruising at a leisurely 60 km/h assisted by a light tail wind. You admire the fresh green, and the ripe and luscious fruit on the trees that line the traffic lanes; the birds giving a free concert to your delight.

Cycle vehicles are everywhere, with passengers and by-passers waving and greeting you. You see people cruising around having a free and healthy snack from the trees.

‘It’s good,’ you think, ‘that we don’t have to worry about pollution when we bite into a fresh fruit offered by someone on the traffic lane side path.’ Land transport has been completely exhaust-free for the last six years. Even all the trains are running on sustainably generated electricity.

As you pedal past fields of naturally grown wheat and vegetables you help yourself to wonderfully aromatic, under-rainforest-canopy-grown fair trade coffee from the traffic lane side bar, transported from Brazil on wind assisted containership. Boats and ships are still using the precious oil, although much less, thanks to the new sail designs.

Just then your daughter reminds you via your personal mobile 3D screen to make a detour and pick her up from school. As you reach the school you return the used coffee cup to the traffic lane side bar for re-use.

Your daughter greets you with a glass of freshly pressed juice made from apples, carrots and beetroot – all grown in the school gardens and juiced in the school kitchen. She is all smiles. She has just won her school’s compost making contest in the temperature category. Her pile made it to a staggering 87°C. ‘She’s a smart little cookie,’ you think. ‘Last year she came second in the earthworm breeding competition.’

Both of you wait at the depot until two seats become available on a flash new, photo-voltaic hexacycle going in the direction of your home. Almost everyone on board wants to stop at the local gardens for some fresh produce, so the hexacycle pulls into the parking lot of the food garden cooperative.

Fresh strawberries are everyone’s favourite as the season is now rapidly coming to an end. You purchase some antioxidant purple potatoes, and you find a nice mix of salad greens as well. All harvested earlier that day.

In the old days, all this would have been organically certified, you remember; now, of course, everything is organic by default. There is no organic labelling required.

Finally arriving home, your husband takes the lettuce off you and, together with some herbs and home-made dressing, based on real egg mayonnaise from the local delicatessen factory, turns it into a beautiful salad. This will go well with the main course, home-made pizza. It only takes four minutes in the adobe, dome-shaped oven, fired with sustainable, locally grown firewood.

After the meal, you relax in front of the 3D screen watching the semi-final games in the soccer championships. The teams look good in their latest hemp fibre outfits. You enjoy the game, while thinking back to the times when television broadcasting was interrupted so frequently by annoying commercials. With very little globalised trade and the emphasis on local production and processing, there is no need for nationwide or international advertisements.

The favourites have won again and enjoy the applause and celebrations from the crowd. ‘Oh well, time for bed,’ you think. After visiting the bathroom you get into your linen nightie sewn by your daughter at school, crawl under the woollen duvet (thanks to Uncle Albert’s home flock of sheep) and cuddle up to your husband. Another day in Ecotopia.

The first passage, by James Lovelock, probably made you feel anxious, angry, sad – or a similar cocktail of unpleasant feelings. It is certainly designed to shock. In the second passage, Holger Kahl’s vision of a possible 2020 has a very different tone designed to make you feel hopeful, intrigued and positive about what the future might bring. Did either communication inspire you to action? If you are like the participants in many psychological experiments, the passage that created negative emotions will have dampened your ability to imagine possible actions, whereas the passage that left you feeling good will have encouraged you to think broadly about how you and others could contribute to a new way of life. You may not have agreed with everything Kahl suggests is possible, but his imagined future is still likely to have ignited that welcome spark of hope.

What is it about feeling good that gets people going? To answer that, let’s look at several psychological studies that have explored this question.

How positive emotions work

Positive emotions work in at least four ways that are of interest here. They open the mind, encourage creativity, make threatening information more palatable, and facilitate cooperation. Hope also has a special role in inspiring us to act collectively.

Positive emotions open the mind

Emotions have three components. First, they are bodily sensations (they aren’t called feelings for nothing), such as hands trembling with nervousness, jaw clenched with anger, and the particular weightlessness that comes from joy. Second, emotions are thoughts – pictures and words that invade our heads in ways that can be highly disruptive, good or bad. Third, they are ‘action tendencies’; that is, ideas about what to do next.¹⁰

Barbara Fredrickson from the University of North Carolina suggests that one of the differences between positive and negative emotions is that positive emotions broaden our sense of what we can do, whereas negative emotions narrow this sense.¹¹ According to Fredrickson, a negative emotion is telling us that something is dangerous, and we had better attend to it. So we narrow our focus to the potential threat and work out how to make it go away. If we feel anger, for example, we have the sense that we or someone we care about has been wronged, and we want to attack in order to restore justice. Anxiety makes us churn the threat over and over in our minds, trying to work out what might happen and what we could do to prevent it. If we are scared we want to retreat. Positive emotions, on the other hand, are a signal that things are going well. One of the implications of this is that we can afford to look around at what the world has to offer. We might try things we haven’t done before, even take a few risks. Positive emotions are therefore conducive to creativity, expansion, and looking for and seizing opportunities.¹²

In one study, Fredrickson and her colleague Christine Branigan divided 104 university students into groups.¹³ Each group watched one of five short films intended to produce particular emotional responses. The film Penguins shows groups of penguins ‘waddling, swimming, and jumping’, which generates amusement. Nature features ‘fields, streams, and mountains in warm, sunny weather’ and elicits contentment and serenity. Witness shows ‘a group of young men taunting and insulting a group of Amish passers-by in the street’ and elicits anger and disgust. To generate anxiety and fear, one group watched Cliffhanger which shows a ‘prolonged mountain climbing accident’. The final film, Sticks, is emotionally neutral and features an ‘abstract dynamic display of coloured sticks piling up’.¹⁴

Having watched their allocated film, the students were asked to concentrate on the emotions aroused by the film and live them as vividly and as deeply as possible. They then had to list everything they could think of to do, given this emotional state. The results showed that participants who had watched Penguins or Nature, the two films that generated positive emotions, had more ideas for actions. The Penguins film, for example, produced fourteen action statements on average, with the Witness film producing just nine statements.

Why did the films produce these differences? Fredrickson and Branigan argue that it is because of the broadening effect of positive emotions and the narrowing effect of negative emotions. The films that made participants feel happy also made them open-minded. They saw life as full of possibilities, so could think of lots of things to do. The films that produced anger and anxiety, on the other hand, encouraged the participants to narrow in and have a more restricted sense of behavioural options.

Fredrickson also suggests that different positive emotions work in different ways. Joy creates the urge to play and be creative. Interest prompts us to explore, take in new information, and expand our understanding of the world. Love creates a desire to play and explore with people we care about. A sense of pride spurs people towards new and better achievements; and even contentment, that blissful sense of being satisfied with what we have, encourages an expanded sense of who we are, where we fit in the world, and what we may be able to contribute.

Fredrickson’s conclusion is that positive emotions are valuable and have become part of our nature, because the actions they inspire make us stronger and more knowledgeable, improve the quality of our social relationships, and help us gather resources. A joyful person will wonder what is over the hill and go and explore; a contented fisherman will be open to teaching others how to mend fishing nets; and the woman who is proud of her garden will plant even more tomatoes the following season. The finishing touch in favour of positive emotions is that the knowledge, relationships and physical resources accumulated during these good times are there even if we become miserable.

Positive emotions encourage creativity

Other studies have found that people in a positive state are more creative. For example, one study set participants the task of attaching a candle to the wall in such a way that wax would not drop on the floor when it burned.¹⁵ To do the task, they were given drawing pins and a box of matches. Seventy-five per cent of the people who had been put in a good mood (by watching bloopers from television Westerns) got the solution, which is to pin the matchbox to the wall and stand the candle in it to catch the wax. Only 20 per cent who had watched Area Under a Curve, a maths film, did so. The task requires a bit of imagination and this was provoked more readily by humour than calculus.

It is not just films that do the trick. People given attractively wrapped candy have been found to seek greater variety when choosing from a selection of snacks than people not given candy.¹⁶ Simply being asked to imagine a recent event that provoked a good mood increased the creative performance of people constructing a lunar hotel from card and tape.¹⁷

The studies described so far used tasks that the participants would not normally encounter in real life, and most used university students as participants. In a somewhat more real-world setting, Carlos Estrada and his colleagues examined the effect of positive emotions on 44 physicians who had been practising for an average of fourteen years. A positive mood was induced in some by giving them candy, while others weren’t so lucky and got no gift. All 44 were given a written case study describing a patient’s symptoms as follows: ‘. . . a 45-year-old female who presented with a 6-month history of arthralgias, fatigue, dark urine, and “red spots” on both legs’. In addition, they could seek tests and obtain the results (which were pre-prepared and available from the research assistant). The doctors were asked to think out loud and their thoughts were recorded. They went something like this: ‘. . . um, red spots, I think something like thrombocytopenia . . . immune hemolysis creating dark urine . . . dark urine makes me, um, think of a possible hepatic disease but that doesn’t seem as likely. So the working diagnosis, thrombocytopenia, collagen vascular disease . . .’¹⁸

The researchers found that being given candy did not affect whether the physicians eventually arrived at the correct diagnosis of chronic active hepatitis, with around 62 per cent doing so overall. But those who had been given the candy were twice as quick to consider liver disease, and also showed much less ‘anchoring’ than th...
