I am living sustainably at a very low level, and have done so for more than 25 years now -- David MacClement[edit]
* I have independent "proof" that my very frugal living is sustainable. I have put my living conditions into the Ecological Footprint calculation. This is based on Mathis Wackernagel's extensive studies. These have been reported in the US journal Proceedings of the National Academy of Sciences (PNAS) (media comment here). The Ecological-Footprint-2.0 FAQ has:
<> One of the global footprint calculations shows the sustainable footprint level is 39 global acres (15.7 global hectares) of bioproductive space for every person in the world.
With a global population of 9 billion for the year 2050, the available space will be reduced to 26 acres.
{Neither of those include leaving} room for the 25 million other species.
* Some comments in my letter to the Positive Futures list run by Communications for a Sustainable Future (CSF), at Colorado.edu:
http://csf.colorado.edu/mail/pfvs/2000/msg03696.html show why I count
my footprint as only 32.2 acres, or less than 83 percent of what's "available" to a human.
* So everyone, everywhere, could live like me and still about 17% of the earth's productive capacity would be left untouched for all other other living things on earth.
{For comparison:
USA: 6.3 earths, 246 acres (100 ha); Canada: 5.7 earths, 220 acres (89 ha); New Zealand: 3.7 earths, 142 acres (57.5 ha); United Kingdom: 3.1 earths, 119 acres (48 ha); France: 2.2 earths, 86 acres (35 ha).}
<>We haven't yet reached 9 billion people, though my life would still be sustainable then, so currently one could live at a 50% higher level (which would decrease as the population on earth increased).
<>The Ecological Footprint calculation makes the assumption that one is living in a North American style, with: car, winter heating (and summer air-conditioning) and meat eating. I'd guess there was a further factor of 2 there, allowing people currently to live at a consumption level up to 3 times higher than mine (though with no space reserved for other living things). (My "diet" page is here.)
I could go back to my 1992 consumption level. (It includes my front page newspaper photo.) Living sustainably, voluntary simplicity, can be done somewhere between my extremely low level and Diane Fitzsimmons' list. It's a matter of choice.
We in New Zealand in the early 1950s used to live as she describes; she's in Norman OK. {in 1957 I gained Amateur Radio callsign: ZL1ASX }.

My wife|* and I (both over 71yo) planned to retire to an autonomous house; I had the PV electrical system, until it was installed for two off-grid houses, one: daughter-and-SIL's on Kawau Island, north of Auckland NZ. _|*: My late wife, Bera MacClement died on 21 July 2013.
