"Every year over 30 percent of the food in the world goes to waste," says the FAO （联合国粮食及农业组织）. To stop food waste, people have come up with the great ideas.
①The world's first food bank started in the US in 1967. People and shops give out their extra food to a place, and others in need go there to eat it, Shanghai has made a"share fridge"in the street. It stores（贮藏） cakes and food given by nearby markets and restaurants. It's free for anyone to enjoy.
②The Real Junk Food Project is a company（公司） in the UK. It says that food past it ssell-by date could still be OK to eat. So they collect such food from supermarkets, and put it on shelves in special cafes. There, the food has no price notes. If you don't want to spend money, you can help do some work there.
③Dining halls in more than half of the US colleges are going tray-less（无托盘）. That means nowhere to put extra dishes. It makes it harder for students to take too much. This small change brings a big difference.
