Ecological footprint
Information
The ecological footprint is a concept developed by Mathis Wackernagel and his co-workers. It attempts to quantify the percentage of the planet's carrying capacity being used up by humanity at any given point in time. Wackernagel showed that, since the 1980s, humanity is spending more resources per time unit than the planet can regenerate in a sustainable fashion.The human ecological footprint is measured in hectares per person.
