Environmental group Greenpeace activists sit on the ground behind a policeman as they protest at a power station in Garona, province of Burgos, in Spain November 20, 2008. Greenpeace blocked the entrance on Thursday to a Spanish nuclear power station facing closure next year and urged the government to shut it down immediately in line with election pledges to phase out nuclear power.
