This is a fascinating thread. Thanks for all the info, guys!
I do have a question, though, about the model to find out how to cause the least amount of death and still feed people. How would orchards factor in the equation? Would the deaths associated with the the one-time tilling of an orchard (composed of mixed trees and other perennial food plants) be more or less than the range meat model? If the orchard produced fruit and nut trees that lived for decades and could feed many people without further digging or slaughter, would it not be prudent to include these fruits and nuts in the "least kill diet," alongside or instead of the range meat?
