What shape best represents the absolute lunacy that is humans and their economic activity? Something Jackson Pollock-esque? Mr Messy off of the Mr Men series, perhaps?Either way, probably not a nice, clean circle. But when you think about it, it really really should be. Cos unless we start (re)learning how to work with what we've got - i.e. sending things round and round in virtuous circles - rather than what we're about to drill / dig / blow up, we're gonna be in an awful pickle.To tell us what a circular economy actually is, why it's not babble, and how Ol buying a tumble dryer may not be inconsistent with it, is author, academic and activist Claire Potter.Claire's book, Welcome to the Circular Economy, is out now.
