Plenitude by Juliet B. Schor The Penguin Press HK$208 The crash of 2008-09 put the nail in the coffin of capitalist business-as-usual. Now the scramble is on as the world searches for a sustainable, green way of living that doesn't wreck the planet. Well, that's the direction Juliet Schor would like to see, anyway. A Boston College sociology professor, economist and best-selling author, Schor has written Plenitude as a road map for lightening our carbon footprints over the next few years, as the human community adjusts to the unfolding green revolution. Idealistic? Better make that essential, if the planet is to survive. The US electric power industry registered US$22.2 billion in profits in 2004. But factor in liabilities associated with three kinds of emissions (carbon dioxide, sulfur oxides, and nitrogen oxides) and that profit became a net loss of US$28.2 billion, Schor writes in one of many telling examples. Plenitude is in the spirit of 'small is beautiful' and the sustainability movement of the 1990s, but in a practical, plugged-in way rich in anecdotes and inspiring examples of how to live sustainably and change our values. The four principles of plenitude are: working fewer hours at 'normal' jobs; learning to provide for yourself much of the food and consumer goods you're used to buying; keeping your consumer life low-cost, low-impact and yet highly satisfying; and revitalising community and social connections. Schor has plenty of clout when it comes to discussing the human cost of the consumer economy, as the author of the best-selling Born to Buy, The Overworked American and The Overspent American. This time she takes us to parts of the world where the plenitude vision is emerging. Urban farmers, do-it-yourself renovators, job-sharers, post-carbon visionaries, off-the-grid solar techies and others who are spending less time making money, using what they have more frugally, and making more room for other aspects of their lives, such as learning, nature and community. These are not the back-to-the-landers of the 1970s - low-tech disciples of Thoreau whose epics of wood chopping were 'hopelessly romantic', Schor writes. 'Self-providing is great, but it needs advanced technology to be liberating.' Brains, not brawn, will drive Schor's brave new world. Plenitude is refreshingly free of jargon and new-age generalisations. Schor does like to use the phrase 'one-planet living' - as in, this is the only orb we have to live on. Maybe it's time we all did.
