By the time you get through your supermarket checkout line, you may have your mind on the next item on your to-do list and not on what your checker person is saying when they ask you if you want them to put your gallon of milk in a bag. You may not even hear them ask. Then suddenly you see yourself leaving the store with the greatest ocean pollutant, enemy of fish and wildlife, the sewer-clogging, petroleum wasting, BPA-spreading blight that is the flimsy, yet ultimately indestructible disposable carryout plastic shopping bag. Milk jugs do not need bags.
