Ecological Footprints Flashcards
What is ecological footprint ?
Environmental accounting tool that identifies the extent to which human activities exceed two limits:
1. Resource consumption
2. Waste absorption
What do ecological footprints measure ?
How fast we consume resources and generate east compared to how fast nature can generate new resources and absorb our wastes.
What is bio capacity ?
Measures the amount of biologically productive land and sea area available to provide the ecosystem services humanity consumes
What is the diffrrence between bio capacity and ecological footprint
Bio capacity is how much bio productive area is available to us ?Ecological footprint is how much bio productive area do we demand ?
How are ecological footprint and bio capacity measured ?
Both are measured in gha.
What happens when ecological footprint exceeds bio capacity
Ecological deficit
What do countries with bio capacity greater than ecological footprint have in common ?
They either have small populations or low population densities.
Small population = less bio capacity and lower ef
Low population density = greater area of uninhabited “bio-productive land”
This is why this method can be unreliable bcos Australia is not sustainable but has high bio capacity
