Shipping food

Division of labor talking about Lacavore's dilemma:
The truth is that the energy expended transporting food is relatively unimportant. According to USDA-ERS data, consumers spent $880.7 billion on food in 2006. Only four percent of these expenditures can be attributed to post-farm transportation costs. One recent study indicated that over 80 percent of the global-warming impacts of food consumption occur at the farm, and only ten percent are due to transportation.

Food shipments are well quantized, great news. How did we get so accurate? The shopping bag, it matches a very stable Gibbs separation to the car door. The shopping cart was then built to match the bag, the grocery store swing door built to match the cart, the grocery aisles built to match the cart and the pallet. We matched the two polynomial that defines consumer shopping trip and the producer food shipment.
