I would inquire if it is viewed that pursuit of primitivist goals would mean an exclusion of agricultural practice, or even horticultural practice. There is evidence from prior to written history stone age people did use an abundance of starchy food and plant sources, contrary to some popular belief. I do not see that sewing and growing plants leads to developing civilization. Any that would be primitivist Christians that pursue it could use the resources of growing food, if with enough variety, which is possible with a good group together, without being so dependent on hunting, as fully adequate nutrition is available without using animals caught for it. Of course, in civilization, just as there were horrors in human genocide, the slaughtering of animals is no better, it is a brutal as can be. How animals were fed, using offal of previous slaughter, is why spongiform encephalopathy is a hidden danger to humans consuming meat. Happy animals grazing until the last moment when they are slaughtered has no reality in fact.
The world is already in trouble with humanity’s part in ruining environments, it comes from the directions taken in civilization, and its societies in the past have collapsed from this. Only extreme changes will avoid this for us.
In living independently as a small community we need to be sensitive to the animal species in light of the extinction rate due to the presence of human civilization. http://www.independent.co.uk/environment/animal-extinction–the-greatest-threat-to-mankind-397939.html Revelation 11 it is sung “We give You thanks, O Lord God Almighty, The One who is and who was and who is to come, Because You have taken Your great power and reigned. The nations were angry, and Your wrath has come, And the time of the dead, that they should be judged, And that You should reward Your servants the prophets and the saints, And those who fear Your name, small and great, And should destroy those who destroy the earth.”
