China will expand its agricultural use of environment-damaging plastic film to boost crop production even as authorities try to curb soil pollution, a government scientist said.
Some 1.45 million metric tons of polyethylene are spread in razor-thin sheets across 20 million hectares (49 million acres) — an area about half the size of California — of farmland in China. Use of the translucent material may exceed 2 million tons by 2024 and cover 22 million hectares, according to Yan Changrong, a researcher with the Chinese Academy of Agricultural Sciences in Beijing.
