Residents urged to dig deep for green vision

Four million trees will be planted in Beijing in 2011 as part of efforts to sow the seeds of a greener capital.

"Another 1,100 hectares of land will be turned into green fields," said Wang Sumei, spokeswoman for the Municipal Bureau of Landscape and Forestry, as the nation marked the 30th anniversary of Arbor Day last Saturday.

"The capital's forest coverage will reach 37.6 percent, compared with 35.47 percent in 2005, while 10 more outskirt parks will be opened to the public before the National Day holiday (in October)," she said.
