Think about the milk that used in food prep.
And all the animal discharges that are used
in farms that grow vegetables. Life be grand.
That’s already a well-known problem in organic farming circles. Some chemicals that are fed into cows pass right through their digestive tracts unchanged and make their manure unusable as fertilizer. I can’t imagine what’s passing through dairy cows’ systems and coming out in their milk is much better. Consider BGH, just for starters.
