I thought of this all on my own... ... ... ... ... ... Milk is made inside a cow,,,,,,,,, then pumped into a steel bulk tank,,,right????,,,which is inside a building no less,,,,,,,,,,,,then shipped by a tanker truck,,,right???,,,then pumped into a facility where it's pasteurized/homogenized, right???,,,,,,,,,then stored inside said facility, inside a giant cooler, right???,,,,,then loaded onto a refrigerated truck bound for your local supermarket, only to find it's way BACK into a cooler,right???, then carefully placed into a display case, INSIDE your favorite supermarket, right???? then you transport said milk be it a half gallon or more to your RAM where it then finds it's way inside your home, inside your frig, awaiting use, right??? ... ... ... ... ... ... ..... Then I have only one question, Why then is it so darn important to package milk in a sun-proof/light blocking/ultraviolet stopping/gamma- ray proof/phaser- ray impenetrable milk jug?????
