If everyone lived like you, we'd need 1.0 planets.
However I take issue with the question about animal product consumption.
While perhaps useful for raising awareness amongst the masses, the
Ecological Footprint Quiz is simply not appropriate to we homesteaders.
Rather inexplicably, we have now in our neighborhood Dr. Dennis
Meadows, co-author with Jorgan Randers and Meadows's deceased wife,
Donella, of "Limits To Growth," first published thirty years ago and
currently in its third iteration. He gave a talk at our community
gathering place on Thursday. He's a typical PhD professor type who
shows lots of slides of charts and talks about them. Chris only had
to jab me awake twice--in fairness I must say that I had a belly full
of pizza and a bit of good Merlot.
Meadows is an accepted expert on how fast we are using up our planet
home. In this case he was preaching to the choir, as most of us who
have purposefully moved to this area are well aware of the
consequences of planetary abuse by we naked apes.
Regarding James's point above, Meadows gave the typical declaration
that we are spending several time the energy calories for each
calorie of meat we consume. The audience chose not to "but" him with
how that is not the case on our homesteads, where we do not raise
animals like agriculturists.
Interestingly, he has purchased a house on acreage near us--a hill
and a holler due north--to which he does not intend to move
permanently just now. It is his escape place.
My view is that, instead of living the answer, he will continue to
only talk about it. Perhaps one day at dinner I will tease him with
that observation.
