The "Sustainability Zeroline" is the first sharp benchmark for sustainability and sets a clear impetus for rethinking future viability consistently. Based on an analysis of the ecologically destructive consequences of resource-intensive economies and the central insight that the dilemma between the compulsion for growth and planetary boundaries becomes practical in the conflict between private goods and commons, J. Daniel Dahm presents the standard for a life-serving economy. For all those who are seriously engaged with the topic, whether in politics, business, as investors, journalists, or concerned citizens, this volume is essential reading for understanding the interplay between humanity and nature.
