Godinman - where do you propose all these bigger free range farms are located? What about in 50 years? 100 years? Also, the end result of free range is still the slaughter of a thinking, pain/fear feeling chicken (or insert other tasty animal).
These proposals, which imho are the inevitable future of meat production, are addressing both these concerns - the practical and the ethical.
So I'm all for it if it is done properly. I think the approach of taking the animal and working backwards is likely to be easier/quicker than efforts to start from scratch and grow meat artificially (the bacon thread). This way you can remove what is unneccessary and keep the skeleton, joints, muscle structure, digestive system for nutrition, etc, etc and by using electrical stimulation to work the muscles could feasibly produce meat as we know and love it with fat, nutritional value etc all included. Better than growing lumps of homogenous mush in vats.
