What you always find in the fridge of a home in the country is an astounding amount of food—the freezer is crammed, the shelves are overburdened, and the compartments are stuffed silly. There is a good reason for this, which is explained by David Harvey in one of his new lectures on the second volume of Capital. Harvey and hundreds of thousands of other people who live in Manhattan do not need big or packed refrigerators because the distance between their apartments and groceries stores is very small. In this way, the storage of perishable items can be shared. The store, as a consequence, provides a common refrigerator. And this sharing improves energy efficiency as a whole. Unlike people in the country and suburbs, a person in the city can pick up needed things easily and in small amounts. The virtues of living in a dense city are as numerous as they are wonderful.
