The one aspect of animal husbandry that hasn't been mentioned is that the practice of sharing our life with animals has created other bio relationships upon which, animals such as wild birds depend. Fields without animals and animal manure do not support the insect life upon which our insect eating birds rely. The bird life around fields used organically for rearing animals is prolific in comparison to the wildlife around single plant crops. The tenuous link to Morgans in all this is that we have probably all noticed the lack of flies on our windscreens over the last few years!
It seems to me that this topic has arisen has arisen out of the connections being made between climate change and health whereby those who want to promote a particular dietary direction try to persuade others that it is in the interest of the planet.
Interesting though this is I would worry that it is distracting us from the real issues emanating from the over-consumption of everything including our intake of food.
