New studies suggest that Chinese agriculture will see conditions "somewhat similar to a nuclear winter" if the smog continues, said He Dongxian, an associate professor at China Agricultural University. In one experiment, she germinated some seeds under artificial light in a lab, and others in a Beijing greenhouse. The former sprouted in 20 days, the latter took more than two months. "They will be lucky to live at all," He told the South China Morning Post newspaper. "Now almost every farm is caught in a smog panic," she added.
