1 . The United Nations put out the most complete report on the problem of food waste. It found that the world wastes about 17% of all the food. That’s about a billion (十亿) tons of food a year. A billion tons is a lot of food—it’s about 931 billion kilograms. The report said that the food wasted is about twice as much as earlier studies had suggested. The study looked at several different ways in which food is wasted—at home, in restaurants and in stores.
It turns out that most food waste—about 61%—happens at home. The food thrown at home works 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 stores.
Food wasted was at about the same rate (比率) in all but the poorest countries. Many people thought rich countries were more likely to waste food than countries that were less rich. That turned out not to be true. In fact, some richer countries wasted far less food than common countries. But people in richer countries may waste less food at home because they are eating out at restaurants more often. That certainly seems to be the case in the US, which has low waste numbers for homes, but quite high numbers for restaurants.
The report points out that hundreds of millions of people are hungry every year. And wasting food is also really 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 says that it’s important for countries to study food waste more carefully in order to make out ways to sew up the problem. Some possible uses for food waste include making food for animals and burning food wastes to create energy. The important thing is to keep food from simply going into rubbish bins.

2 . Windy days are common during spring. Did you know that strong winds can even influence trains?
On May 1, 2021, strong winds in Baoding, Hebei Province, caused a foreign thing to get caught in power lines above the railway lines, stopping some trains. Some passengers were even stuck on their trains while traveling.
High-speed trains receive power from wires (电线) hung above the railway lines, according to Worldwide Rails, a rail news website. As an important power source for high-speed trains, why are these lines so easy to break in the face of wind.
The line itself is strong, but too many light things can still influence them. Kite wires are one of the biggest problems for railway workers. If one end of a kite wire touches a power line and the other end touches the ground, it will cause a short circuit (电路) on the line, causing a loss of power.
Other materials, such as tin foil (锡纸), can also cause problems. If they are blown onto train power lines, they can stop trains from getting power.
In many cases, train workers have to remove foreign things from power lines themselves. The bigger the foreign thing is, the harder it is to clean up. Bird nests are one of the most difficult.
Because of their height and strength, power lines have become a popular place for birds to make homes. Birds carefully make their homes with branches and other materials. “They keep us busy. One day we deal with one bird's nest and the next day they’ll build another,” a Xiamen train worker told Xiamen TV. How to solve? To make man-made nests and put them along the lines to fool birds into thinking the place is taken.
