Last night I caught the first episode of the BBC documentary "The Men Who Made Us Spend" (if you live in the UK and you're quick, you can catch the who series on iPlayer). It was a fascinating (and balanced) history of the rise of consumerism from the 1924 Phoebus Cartel of lightbulb manufacturers (who agreed to limit the life of their products to 1000 hours when 2500 was the norm) through to those poor deluded souls who camp outside Apple Stores to be the first to get their mitts on the latest slightly better model iPhone.
The most painful moment in the episode was when presenter Jacques Peretti asked Stephen Howard, Global Head of Sustainability at IKEA, how he reconciled the company's claims of sustainability with their continued marketing of throwing away existing furniture from the famous "Chuck Out The Chintz" to the modern day "My Old Sofa is So Going to the Kerb". Poor Mr Howard could only stammer that he would ask the question of the marketing department.
This is a huge issue, not just one for IKEA - for at least 60 years the modern economy has relied on old products going out of fashion and being replaced long before they physically break, a kind of Faustian pact between consumer and producer with planetary limitations being the party pooper.
But while it is easy to deride such consumerism, the problem is that the modern capitalist model has brought fashionable clothes, furniture and vehicles to billions on low incomes - who wants to go back to the model where the moneyed classes can afford comfortable lifestyles while the majority scratch a living in homesteads and city slums? I love my tech as much as the next person, and it would be churlish of me to deny the process which has brought us huge leaps from my first computer, a BBC Model B, to my (not quite) cutting edge iPhone4.
Fortunately there are solutions. The circular economy has the power to keep materials being useful, just in different forms so function and fashion can keep moving forward. The digital economy means that we can consume huge amounts of information - movies, books, music, TV etc etc without consuming as much stuff. eBay has opened a huge market for secondhand goods, Freecycle one for freebies. And the technology which means at 210mph Porsche super car can have emissions less than that of a Prius show that planet friendly technology doesn't have to mean stuff made out of cardboard.
It's a big ask, but I think we can have our lifestyle and sustainability, if we really put our minds to it.
