Ⅲ. 沙漠治理
Daniel 认为虽然自己的力量很渺小，但是如果每个人都愿意坚持保护环境，我们一定能看见一片绿色的未来。
Standing on the top of a sand dune (沙丘), Mohammed Abdulkarem from Yemen looked down at a man - made forest. He was on a trip with about 30 international students from Ningxia Medical University to visit Baijitan in Ningxia, China. Abdulkarem and his schoolmates were told that the 60 - kilometre - long and 30 - kilometre - wide forest can help stop the sand from the Mu Us Desert.
However, in the 1950s, the green space was once a desert. So how did all this happen? Over the past 70 years, local people and volunteers have planted a large number of trees to stop the Mu Us Desert from becoming larger. "It's hard to believe," Abdulkarem said. "My country also needs to protect people from the dangers of deserts, and I see a great example here."
Then the students learned how to make a straw checkerboard (草方格), a local method of stopping sand from moving. "It's really difficult and challenging, and I'd never known that straws could be used to fix sand, which is cheap and works really well," Abdulkarem said. "Controlling desertification takes a lot of time and energy. I'm deeply touched by the spirit of sand controlling year after year."
The students also visited the Museum of Baijitan, which records the history of how local people fight against desertification. "I have learned a lot from this trip. I see the great work China has done to protect our planet, and other countries should learn from China," said Davis Munashe from Zimbabwe.
