Hey man, don't need to go that far. The concept and context of his argument are solid. Look at diamonds, for instance. It's done, even if his example wasn't spot on. Maybe. Where I am the dairy farmers are selling their cattle for meat, because the supermarkets have strong armed such low prices, they can't afford to even operate. While the milk on the shelf isn't cheap.
Don't milk cows, lactation stops. No milk until the next calf is born. Outside the ethics of bovine milk, if the supply chain has ground to a halt, and food safety regulations mean you can't sell warm, unpasteurised, unfiltered milk at your front gate (Yay, faeces and gravel) then it's going to be tipped because it needs to be in this instance.
Powdered milk, also called milk powder,[1] dried milk, or dry milk, is a manufactured dairy product made by evaporating milk to dryness. One purpose of drying milk is to preserve it; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated, due to its low moisture content. Another purpose is to reduce its bulk for the economy of transportation.
