Using just 25 percent of that wasted food could feed 870 million hungry people, which would end world hunger. The people of France wasted 234 pounds of food per person, which is much better than some other countries. In the past, France wasn't good at controlling food waste, but now the country takes the lead.A law was made by French government. It made France the first country in the world to prevent supermarkets from throwing away unused food. Now supermarkets of a certain size must donate unused food, or they will face a fine. There are other rules requiring schools to teach students about food sustainability(可持续性). They also ask companies to report the food waste numbers in their environmental reports. And restaurants should offer take－out bags to customers.“These laws make it a standard to reduce waste，” says Marie Mourad, a student in Paris who has written several reports on French food waste. “France is not the country that wastes the least food, but Frenchmen have become the most active because they want to be the example in Europe.”“Preventing supermarkets from throwing away food means a lot，” says Jonathan Bloom, a famous writer. “This step has also influenced parts of French food industry.”It is everyone's duty to fight against food waste.
