countries by ecological footprint. This table is based on 2007 data from the Global Footprint Network published in 2010. Data is given as global hectares per capita. The world-average ecological footprint in 2007 was 2.7 global hectares per person (18.0 billion in total). With a world-average biocapacity of 1.8 global hectares per person (12 billion in total)‚ this leads to an ecological deficit of 0.9 global hectares per person (6 billion in total). If a country does not have enough ecological resources
