I just opened a box of Corn Flakes, the huge box, and it was basically half full. So the other half of the box was just wasted space. Just think of how many products are shipped in containers that are cleverly designed by marketing people simply to convince us we are getting more product than they actually deliver. How much space is wasted in each truck traveling down the highways so company X can convince us to upsize our purchase. How much space in a store is wasted because of packaged air. The average Walmart store gets two trucks per day. Just one company could save alot of energy. Plus shipping it to the distribution centers in the first place.
