The world economy has expanded to the point where a number of planetary boundaries, of which climate change is the most talked about, are being severely stretched. There are simply too many unsustainable trajectories for the system to continue as it has for the past several decades for several more decades to come. Moving to a more sustainable development path will require making truly basic changes in what, how, and how much is produced and consumed. That, in turn, will require nothing less than restructuring the economy, a makeover of consumer lifestyles, and re-examining values.
