Sex Changes For Trees

In an effort to relieve the city from pollen infestation, Beijing's female poplar trees will receive 'sex change operations'.

Reuters noted, "Hospitals in Beijing have received increasing numbers of patients who suffer from asthma or allergies after inhaling the pollen, which blankets the city in a snowfall of white fluff, reports said. It would not be China's first attempt to alter nature."

Hey Beijing! If you want another way to improve air quality, try reducing factory pollution...
