By largely ignoring the core economy, mainstream economics has also overlooked just how much the paid economy depends upon it. Without all that cooking, washing, nursing and sweeping, there would be no workers — today or in the future — who were healthy, well-fed and ready for work each morning.

true plantsman knows, gardening is far from laissez-faire. In their book The Gardens of Democracy, Eric Liu and Nick Hanauer argue that moving from ‘machinebrain’ to ‘gardenbrain’ thinking calls for a simultaneous shift away from believing that things will self-regulate to realising that things need stewarding. ‘To be a gardener is not to let nature take its course; it is to tend,’ they write. ‘Gardeners don’t make plants grow but they do create conditions where plants can thrive and they do make judgments about what should and shouldn’t be in the garden.’46 That is why economic gardeners must throw themselves in, nurturing, selecting, repotting, grafting, pruning and weeding the plants as they grow and mature.

global greenhouse gas emissions is highly skewed: the top 10 percent of emitters — think of them as the global carbonistas living on every continent — generate around 45 percent of global emissions, while the bottom 50 percent of people contribute only 13 percent.

availability bias — making decisions on the basis of more recent and more accessible information loss aversion — the strong preference to avoid a loss rather than to make an equivalent gain selective cognition — taking on board facts and arguments that fit with our existing frames risk bias — underestimating the likelihood of extreme events, while overestimating our ability to cope with them.

For over 70 years economics has been fixated on GDP, or national output, as its primary measure of progress. That fixation has been used to justify extreme inequalities of income and wealth coupled with unprecedented destruction of the living world. For the twenty-first century a far bigger goal is needed: meeting the human rights of every person within the means of our life-giving planet.

Below the Doughnut’s social foundation lie shortfalls in human well-being, faced by those who lack life’s essentials such as food, education and housing. Beyond the ecological ceiling lies an overshoot of pressure on Earth’s life-giving systems, such as through climate change, ocean acidification and chemical pollution. But between these two sets of boundaries lies a sweet spot — shaped unmistakably like a doughnut — that is both an ecologically safe and socially just space for humanity. The twenty-first-century task is an unprecedented one: to bring all of humanity into that safe and just space.

cleaning up a nation’s air and water by shifting from manufacturing to service industries doesn’t eliminate those pollutants: it sends them overseas, letting someone else, somewhere else, feel the burn while those back home can import the neatly packaged finished product.

If growth were to be abandoned as an objective of policy,’ wrote the economist Wilfred Beckerman in 1974, ‘democracy too would have to be abandoned . . . the costs of deliberate non-growth, in terms of the political and social transformation that would be required in society, are astronomical.’26 Beckerman’s influential book In Defense of Economic Growth was a scathing response to the Club of Rome’s Limits to Growth report and it became an instant pro-growth classic.

Over the course of two centuries — from the 1770s to the 1970s, as economic man’s depiction morphed from a nuanced portrait to a crude cartoon — what had started as a model of man had turned into a model for man.

Life on Earth has the chance of another five billion years in its favour, at which point our star, the sun, will start to die. Earth’s Holocene-like conditions could continue for another 50,000 years — as Chapter 1 described — if we humans learn to navigate the Anthropocene without pushing our planet into a far hotter, drier, and more hostile state. The economies that we create could keep on thriving — not growing, but thriving — for millennia too, if we manage them wisely.
