1 ECOLOGICAL FOOTPRINT Wednesday March 3, 2010

2 What is it?… Ecological Footprint: Ecological Footprints are: 1. a measure of human impact on the Earth. 2. The footprint equals the Earth’s cost to sustain one person. 3. It’s measured in hectares The ecological footprint is a measure of human demand on the Earth's ecosystems. It compares human demand with planet Earth’s ecological capacity to regenerate.

3 Ecological Footprint World Average – 2.2 hectares Biggest Footprint – United States – 9.6 hectares Smallest Footprint – Bangladesh – 0.5 hectares Average Canadian Footprint – 8.6 hectares – Canada has the 3rd highest footprint in the world!

4 Why is Canada’s average footprint so big? We require ….. 0.2 hectares of land for water (to drink & provide seafood) 0.3 hectares of land for grazing land for meat and dairy 1.4 hectares of land for timber wood and paper products 1.6 hectares of land for farmland to grow the food we eat 4.7 hectares of land and needed to absorb the greenhouse gases produced by driving around town, through the running of air conditioners and the import of exotic goods and foods Total: 8.6 Hectares!
