Been talking about this for years on Vault-Co. Years.
The ruling classes don't want dead beasts taking up natural reserve land. It seems a waste to them that cattle should wish a box and a marker after death, it's all too much to bother for a mere domesticated beast.
Keep watching for more of this propaganda. I heard it was mentioned at the last Bilderberger meeting as a big tick on the Agenda 21 implementation. No more holes for dead beasts. It's a waste of perfectly good land. Up the smokestack you go. Remember, when the Nazis did it, it was wrong. Reminds of the end of George Orwell's ANIMAL FARM.
How long before somebody decides just cremating people is a waste of resources that could be recycled into the system?
