ECOLOGICAL FOOTPRINTS

3. CALCULATING ECOLOGICAL FOOTPRINTS
It is measured in ………….. or ……………….
Calculates the amount of the earth’s bioproductive space is needed to keep a population at its current level of resource consumption
Takes into account
…………….. land
………………
………………… needs
……………………costs
………………….. extinction

5. GLOBAL AND NATIONAL TRENDS
Planets biocapacity is ………….hectares per person
Some countries are over …………… hectares per person
This results in a deficit of …………..hectares person
Shown by failing ecosystems, soil degradation, climate change

8. Humanity's demand for resources is now outstripping supply by about 25%, as the growth of our ecological footprint shows. Meanwhile the health of the planet's ecosystems, measured by the living planet index, is falling, at "a rate unprecedented in human history," according to the WWF.

11. Biocapacity affected by
…………………………. (which is increasing)
With current population rates the ecological footprint available is reduced to …….. hectares
if current consumption rates continue then we would need ………. planets to sustain the world population

12. USA has the largest per capita footprint- ………… hectares
With these rates of consumption the planets biocapacity could only support ………..billion people
Bangladesh has a per capita footprint of ……….. hectares
With these rates of consumption the planet could support …………….billion people!

Graphs track the per-person resource demand (Ecological Footprint) and resource supply (Biocapacity). Biocapacity varies each year with ecosystem management, agricultural practices (such as fertilizer use and irrigation), ecosystem degradation, and weather

16. Global ecological footprint grew from ………
Global ecological footprint grew from ……….% of the planet’s biological capacity in 1961 to ………..% in 1999.
Predictions show that this trend to rise to ………………..% of the earth’s biological capacity by 2050
