The use of land
1. The average American requires about 24 acres worth of land productivity to produce all the food, textile, wood, and similar land products, produce energy, and manage the garbage that he or she consumes in life.
By comparison, the average available land on the planet per person is something less than 5.
You can run a "footprint" that meets some international ecological footprint standards on "earthday.org"
*The model obviously has some biases, at least for North America - for example I suspect the presumption if I eat meat is that it's coming from some sort of factory/industrial-based production (with the resultant energy inputs) when, in fact, we each much of our own meat grown right on our little acreage. But, even so, the real consumption is in petro-based or supported things like cars, airplanes, and electricity (we have a lot of hyro-power here, but still the support, transmission, distribution, and access and parts to maintain those points is supported by fleets of trucks moving goods and services hither and thither).
2. Another estimate is that it takes about 9-10 acres of land to support the average New Yorker - even though they don't have the land and it's "out of sight" to them, it's still necessary. That's some "food for thought."
Time's a-comin' when this unsustainable life of luxury will finally bite us in the @ss. Some suggest the next 10 - 20 years.
