I see shades of mad cow disease, Soilent Green. By feeding cows other cattle floor sweepings is how that all started. It isn't "natural" to consume what nature intended the body to expell from its self as WASTE matter. Recycling works with non living material like metal, glass, paper, not consumption for living animals.
I see you must have missed the "Meat without Animals" threads this afternoon.
