I am all for the primal diet - I've been loving it so far. My only worry is the same that has been put out by vegetarians for a long time: that raising animals requires lots of plant matter that could directly feed a great many people.
Is it that following the primal diet becomes a luxury of the 1st world? Could it be that by raising so much meat we are denying other human beings from food to live? Is there any data to prove or disprove this reality? Do any other Grokkers here share my fears, or do you think that non Americans/Westerners should just suck it up and deal?
