As we face a profound environmental crisis, we often think that it can be overcome by smart systems and green innovations, but this is risky since increasingly complex technological solutions rely on less abundant materials. A best-seller in France, this English language edition introduces readers to an alternative perspective on our technological future. The book skilfully goes against the grain to argue that 'high' technology will not solve global problems and envisages a different approach to manage our resources and build a more resilient and sustainable society.
