The footprint concept:
All the natural raw materials we consume for eating, living, travelling, etc. need space on our planet to grow back. Likewise, nature needs resources to break down our waste (e.g. forests to bind the CO2). The ecological footprint makes this land requirement clear.
The red/white/red footprint calculator:
The calculator was launched on the initiative of the Austrian Ministry of Agriculture, Forestry, Environment and Water Management to give people the opportunity to find out their own personal footprint. It was implemented with scientific support (Institute of Social Ecology (SEC)) and the assistance of environmental experts from the Footprint Platform.
What you can do:
The footprint not only clearly illustrates the ecological limits of our planet, it also shows what actions everyone can take to personally help prevent the destruction of our planet.
