The idea that India and China becoming more American in their tastes, leading to catastrophe, is a fallacy. It is a very simple, perfect, and totally incorrect progression. Here is why:
Because a strange thing happens when you take a finite thing (meat production), add in long distances to transport it (these countries produce a tiny fraction of their consumption), and growing demand....
Prices go through the roof.
As this happens, as it already has begun to, the more traditional Chinese, Indian, Brazillian, etc, foods of a given country will heavily undercut the sale of beef and pork. Meat of "American" style will become something of a status symbol for the wealthy, and this changes the consumption equation.
Secondly, we are in absolutely no danger of the world's eating habits becoming "too paleo". This implies meat that is naturally-raised, lived well (and shortly), and is then eaten head to tail. For example, my neighbor has two cows that will be slaughtered on Nov 4. Both are only 4 years old, have lived on pasture their entire lives, calved, and will be leaving us soon. We will be using the hide for blankets and rugs, eating all but the gut organs which will go as dog food, and will be feeding about 8 people for over a year.
This is the future....not a way to further create efficiencies into a centralized system, but a gradual DE-centralization of food and meat production. Transport prices will necessitate it, and those that insist on STAYING centralized should get used to paying a king's ransom for beef or pork. This includes parts of the US that only know how to consume meat, and produce very little. The same is true for whole countries. The theme will be the same for the next few decades: Make it close to home or be ready to pay out the nose for it. Period.
"They now look to a single and splendid government of an aristocracy, founded on banking institutions, and moneyed incorporations under the guise and cloak of their favored branches of manufactures, commerce and navigation, riding and ruling over the plundered ploughman and beggared yeomanry." - Thomas Jefferson, 1826
