A strong wind and a piece of plastic film changed the vacation plans of thousands of people. China is the country

with the largest amount and coverage of plastic film in the world. This thin plastic film has contributed greatly to China's food

 security and annual vegetable supply, but at the same time, it has also left a huge amount of difficult to degrade white garbage 

in the soil. What kind of story has plastic film gone through in just a few decades, from the "White Revolution" of increasing production 

and income to the difficult to control "White Pollution"? Recently, a reporter from the Beijing News invited Yan Changrong, a researcher

 at the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, 

director of the Key Laboratory of Agricultural Film Pollution Prevention and Control of the Ministry of Agriculture and Rural Affairs,

 and president of the International Agricultural Plastics Association, to tell the story behind plastic film.
