The only metric that tracks how much nature we have - and how much nature we useEcological Footprint accounting, first introduced in the 1990s and continuously developed, continues to be the only metric that compares overall human demand on nature with what our planet can renew - its biocapacity - and distils this into one number: how many Earths we use.Our economy is running a Bernie Madoff-style Ponzi scheme with the planet. We use future resources to run the present, using more than Earth can replenish. Like any such scheme, this works for a limited time, followed by a crash.Avoiding ecological bankruptcy requires rigorous resource accounting - a challenging task, but doable with the right tools.Ecological Footprint provides a complete introduction, covering:Footprint and biocapacity accountingData and key findings for nationsWorldwide examples including businesses, cities, and countriesStrategies for creating regenerative economiesWhether you're a student, business leader, future-oriented city planner, economist, or have an abiding interest in humanity's future, Footprint and biocapacity are key parameters to be reckoned with and Ecological Footprint is your essential guide.AWARDSSILVER | 2020 Eric Zencey PrizeSILVER | 2019 Nautilus Book Awards: Ecology & EnvironmentFINALIST | 2019 Foreword INDIES: Ecology & Environment
