Abstract
The idea that builds on the recognition that the Earth is a finite world, the resources are not endless, and thus the vision of continuous growth cannot be sustained can be traced back to the 1960s. Global problems had already occurred by then, and trends calculated from the data indicated a rapid disaster for the future. Humanity is at crossroads, and even the directions are still unclear. In the mid-1980s, an increasingly ecological approach appeared in politics, development policy, and international institutions.
