1. The Ecological footprint

2. Per capita (per human) ecological footprint (EF) is a way of comparing consumption and lifestyles, and compairing it against nature’s ability to provide for this consumption.Per capita (per human) ecological footprint (EF) is a way of comparing consumption and lifestyles, and compairing it against nature’s ability to provide for this consumption. The consumption of energy,The consumption of energy, Biomass (food, fiber),Biomass (food, fiber), Building material,Building material, Water and other resourcesWater and other resources are converted into a measure of land area called ’global hectares’ (gha). are converted into a measure of land area called ’global hectares’ (gha). What is it?

Different footprint sizes The U.S. : 9.6 ghaThe U.S. : 9.6 gha Finland: 7.6 gha (four times the capacity) ‏Finland: 7.6 gha (four times the capacity) ‏ Belgium: 5.6 gha (over three times the capacity) ‏Belgium: 5.6 gha (over three times the capacity) ‏ Hungary: 3.5 ghaHungary: 3.5 gha China’s: 1.6 ghaChina’s: 1.6 gha Mozambique: 0.6 ghaMozambique: 0.6 gha Notice! In order for the Earth to survive, nobody should have a footprint bigger than 1.8!

4. Notice that the more developed countries have, in general, bigger footprints.

7. The Footprint as a way of comparing is criticized because it doesn’t consider all aspects (biodiversity, trade between rural and urban, nuclear vs. coal etc.) ‏ So sometimes having a small footprint isn’t the most important thing. The Finnish biocapacity (how much our nature can produce) figure is among the world’s highest at 12.0The Finnish biocapacity (how much our nature can produce) figure is among the world’s highest at 12.0 The United States, for example, the ecological footprint is 9.6, while biocapacity is less than 5.The United States, for example, the ecological footprint is 9.6, while biocapacity is less than 5. China and the Arab emirates are even worse off (because of growing demand).China and the Arab emirates are even worse off (because of growing demand). But!
