Ecological Footprint is a resource management tool that measures how much land and water area a human population requires to produce the resources it consumes and to absorb its wastes under prevailing technology. Essentially, it measures human demand on nature.The science is actually pretty robust which gives it tremendous merit. Right now, humanity’s Ecological Footprint is over 23% larger than what the planet can regenerate. Ecological Footprint accounting shows that, as of October 6, 2007, humanity has consumed the total amount of new resources that our planet can produce this year.
Figure out what your personal ecological footprint is. Full disclosure of my own personal Ecological Footprint can be found after the jump (and no, I’m not proud of it).
Q: Assuming that (a) Tom Cruise’s level of consumption is in parallel with his annual salary, and that (b) everyone on earth has the opportunity to live like Tom Cruise: How many Earths would we need to sustain this level of consumption?
A: About 2700 Earths. 2700 fricking Earths!
Food: 4.2 acres
Mobility: 2 acres
Shelter: 6.9 acres
Goods/Services: 5.9 acres
TOTAL FOOTPRINT: 19 acres
In comparison, the average ecological footprint in the United States is 24 acres per person. Worldwide, there exist 4.5 biologically productive acres per person. If everyone live like me we would need 4.3 planets.
