According to Wikipedia, "A distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers."
Evidently, distribution centers are crucial in the retail service industry. The existence of these buildings in our cultural landscape (one of our geography themes) suggests that our society is partly driven by consumerism. I believe that the US would be considered a stage 5 country according Rostow's economic development theory due to our nation's ability to produce and consume material goods. These distribution centers also suggest that our globalized society (another theme!) values time and money; many business owners and consumers want their products in an instant.
According to the World Factbook,[5] the United States imports a net 12 million barrels (1,900,000 m3) of oil a day (MMbd), so the SPR holds about a 58-day supply. However, the maximum total withdrawal capability from the SPR is only 4.4 million barrels (700,000 m3) per day, so it would take over 160 days to utilize the entire inventory.
