Regarding the environmental impact and sustainability: http://www.westonaprice.org/mythstruths/mtvegetarianism.html...

Here's another take: http://www.second-opinions.co.uk/vegetarian.html#link1

One missing piece regarding the idea of sustainability of ruminant farming versus grain farming is that the former tends to rejuvenate the soil, and can be performed in areas unsuitable for crop growth. The latter, on the other hand (unless performed in concert with ruminant farming), encourages deforestation (to locate healthy, nutrient dense soil), using up the nutrients in the soil, maintaining the soil via petroleum fertilizers, and then abandoning the land once depleted/eroded.

Ruminants are a key piece to the puzzle in sustaining the fertility of the soil when growing crops.

Oh I'm all about eating meat, just not exclusively. Both of those links advocate grazing livestock, which I 100% support and think it also tastes better. Better than the grain-fed meat that is so cheap and plentiful in the US (I think that's where thras is.) But meat raised that way is more expensive, which makes it difficult to eat only meat and greens (the latter of which are likely to be trucked halfway across the country.) This is how he's "hacking" the food economy: taking advantage of agriculture subsidies that distort the price of meat.

Exclusively eating local produce, grass-fed beef, free-range chickens and their eggs is not only seriously expensive, but in many parts of the US (like where I am) nearly impossible.

Whole grains and legumes, however, are pretty healthful and easy to grow, AFAIK.

Of course I was simply addressing the sustainability comment, not the economics involved.

Regarding economics, I suppose the unanswered question is how would a reallocation (or reduction, depending on your political bent) of government subsidies affect the feasibility/availability of grass-fed beef compared to the CAFO variety? What would happen if grass was subsidized instead of/in addition to grain?

Even now, it's possible to buy sustainable meat at comparable prices (http://www.getrichslowly.org/blog/2006/12/13/how-to-buy-a-si...) if you go in for a half or quarter cow. However, this involves quite a bit of work (if only it were as simple as logging into buymycow.com and ordering 200lbs to be vacuum sealed & delivered at your doorstep!).

You're making me hungry.
