Greenpeace activists dress up as trees during a protest outside the Chief Executive's office in Hong Kong October 2, 2007. The environmental protection group asked Hong Kong Chief Executive Donald Tsang for a master plan against global warming in his upcoming annual policy address. Greenpeace said the move taunted Tsang's earlier claim in APEC to plant 11 million trees to combat global warming, which lags far behind the Beijing government's policy pace and shames Hong Kong's international image. The placard reads "Give me a weather policy". REUTERS/Greenpeace/Handout (CHINA). EDITORIAL USE ONLY. NOT FOR SALE FOR MARKETING OR ADVERTISING CAMPAIGNS.
