Cleaning your plate may not help feed hungry children today, but the timeworn (陈旧的) advice of mothers everywhere may help reduce food waste from the farm to the fork and make it     1    (easy) to feed the world's     2    (grow) population. Hard data is still being collected, but experts in Chicago say that each American     3    (throw) away 33 pounds of food each month, which means everyone throws away almost 400 pounds of food every year. In richer nations, fruits and vegetables end up in the trash because they aren’t pretty enough     4    (meet) standards, and have gone bad in a home refrigerator. In developing countries, much food goes wrong     5     it gets to the market because of poor roads. But the effect of food waste is far     6    the kitchen. Agriculture is the world's largest     7    (consume) of water, a big consumer of energy.
