A group of researchers, led by a UNSW sustainability scientist, have reviewed existing academic discussions on the link between wealth, economy and associated impacts, reaching a clear conclusion: technology will only get us so far when working towards sustainability—we need far-reaching lifestyle changes and different economic paradigms.
In their review, published today in Nature Communications and entitled Scientists' Warning on Affluence, the researchers have summarized the available evidence, identifying possible solution approaches.
"Recent scientists' warnings have done a great job at describing the many perils our natural world is facing through crises in climate, biodiversity and food systems, to name but a few," says lead author Professor Tommy Wiedmann from UNSW Engineering.
"However, none of these warnings has explicitly considered the role of growth-oriented economies and the pursuit of affluence. In our scientists' warning, we identify the underlying forces of overconsumption and spell out the measures that are needed to tackle the overwhelming 'power' of consumption and the economic growth paradigm—that's the gap we fill.
"The key conclusion from our review is that we cannot rely on technology alone to solve existential environmental problems—like climate change, biodiversity loss and pollution—but that we also have to change our affluent lifestyles and reduce overconsumption, in combination with structural change."
