The United Nations put out the most complete report on the problem of food waste. It found that the world wasted about 17% of all the food. “That’s about a billion tons of food a year.” The study looked at some different ways in which food was wasted at home, in restaurants and in shops.

It turned out that most food waste, about 61%, happened at home. The food thrown out at home worked out to about 74 kilograms for each person every year. Restaurants caused about 26% of the food wasted. The other 13% was thrown away by shops.

Food wasted was about the same rate（比率）in all but the poorest countries. Many people thought rich countries wasted more food than the countries that were less rich. But it turned out not to be true. In fact, some richer countries wasted less food than common countries. People in rich countries wasted less food at home because they ate out more often.

The report pointed out that millions of people were still hungry. Wasting food is also bad for the Earth. Farming creates between 10% and 30% of the world’s greenhouse gas emissions（温室气体排放）which make the environment worse.

The report said it was important for all countries to study food waste more carefully to find ways to solve the problem. Some possible uses for food waste include making food for animals and burning food waste to create energy. The important thing is to keep food from simply going into rubbish bins.
