阅读以下英文,完成下列题。
People often use their phones to take pictures of their meals—especially fancy(华丽的)ones—to share online. But Clear Plate, a WeChat mini-program, encourages you to take pictures of your empty plates after a meal. The program’s AI(智能)“sees” that your plates are empty and gives you points. You can use these points to buy yourself gifts or give away the points to buy meals for children in poor areas.
The program was developed by Liu Jichen, 23, a student at Tsinghua University. Liu came up with the idea in 2017.“Technology is a good way to cut down food waste,” said Liu. He put together a 20-member team to work on the program. To teach the program’s Al how to recognize(辨别)empty plates, the team spent half a year collecting100,000 photos from restaurants in 10 cities.
The team also started a campaign called Clear Your Plate in Chinese universities in 2018.Students compete against each other to see who can get those most points in Clear Plate. Now in its third year, the one-month campaign has reached 1, 017 schools. In 2020, almost 16 million people took part in it, cutting down food waste by 862 tons and carbon emissions(排放)by 3, 337 tons.
Thanks to his work, Liu was chosen as one of the United Nations’ 2020 Class of Young Leaders for the Sustainable Development Goals(可持续发展目标). “We hope our efforts can encourage young people to cherish(珍惜)the food and save the food,” Liu said.
