One feature of the global food economy is the simultaneous import and export of the same items, a phenomenon known as redundant trade   In California, for example, domestic cherries are exported to Canada and Japan, while a nearly equivalent number of cherries are imported from Chile, Italy, and Germany  California also exports and imports nearly identical amounts of lettuce and almonds
Although shipping fresh fruits and vegetables is an expensive undertaking, there is a justifiable economic rationale for redundant trade
The economic globalization of redundant trade allows for the sharing of cultural norms and values.
