This is all exacerbated by the decline in birth rates. Milk marketing promotes milk as a nearly perfect food - and it is, but it is costly for the ~6% of nutritional content in milk, (skim and 2%BF being lower). I only use milk for tea and often a gallon sours before I finished - so I switched to superfiltered bagged 3 packs, as the sealed ones last a month in the fridge. So you have super cows making more and a populace drinking less - it does not augur well...
