Recent research suggests that the smog enveloping Beijing, along with six other Chinese cities that together rank as 7 of the worldâ€™s 10 most polluted, is spreading into the countryside and killing off rural vegetation.
Particularly harmful is ozone, which damages the pores on leaves responsible for regulating how much water transpires from the plant, in turn impacting water uptake and regional groundwater and surface water supplies.
