Answer:
People should be taught to preserve food so that they do not waste any food at all.
Explanation:
If we preserve food so that we do not wast any food at all, we wouldn't have so much food. In fact, we would only have as much food as we need if we preserved the food. If this were the case, the poor would have access to food that isn't being preserved for later use because other foods, by people who can afford food, are already preserving food. Therefore, they wouldn't need to buy so much food.
