It also shows to what extent their consumption can be supported by their local ecological capacity. One key finding is that today, humanity as a whole uses over one third more resources and eco-services than what nature can regenerate. In 1992, this ecological deficit was only one quarter. After introducing the rationale and assessment method for this study, the report explains how such biophysical analyses can help build a sustainable future. A computer diskette is included in this report. It contains the data and the calculations for the ecological footprints for each country. THIS “RIO+5 FORUM” STUDY WAS COMMISSIONED AND FINANCED BY THE EARTH COUNCIL, COSTA RICA.1 1 ECOLOGICAL FOOTPRINTS OF NATIONS Why measure our use of nature?
