In Japan a huge amount of food is discarded every year without being eaten. The volume of such uneaten food is almost equal to Japan's annual rice crop. What causes us to throw away such a large quantity of food? Some analysts point out that it is our food distribution system that causes us to 5 dispose of so much food. Our system is more strictly regulated than in other advanced countries. Others argue that our tendency to prefer food with longer shelf life results in such a situation. Never can we make changes unless we are determined to change the way we sell, buy, and stock food. 1. discard = throw away ~; dispose of ~; get rid of ~ [~3] 7. shelf life [M] 900 1. (TF) 2. (TF) 3.
