In Folding the World, Professor Anders Levermann confronts the defining issue of our time: how humanity can thrive on a planet with finite resources. Drawing on his background in theoretical physics and his work at the Potsdam Institute for Climate Impact Research, Levermann proposes a groundbreaking economic framework for sustainable development, founded on the mathematical concept of "folding".As the age of expansion draws to a close, our need for rapid societal development is colliding with the physical limitations of Earth. Accepting the harsh reality of this situation, we face a dilemma. The desperate call for renunciation and recession, while understandable, is counterproductive; it does not solve our dilemma. The mathematical principle of folding offers an alternative: the possibility of infinite motion within a finite world not growth into more, but growth into different. This principle is not confined to the realm of theory it translates into actionable strategies, from carbon trading to corporate taxation, representing a tangible solution that could help chart the course for our shared future.
