Ecological FootprintEcological 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!

Why is Canada’s average Why is Canada’s average footprint so big?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
