Blue sky now!

 Greenpeace East Asia activists projected the words "Blue Sky Now"! onto a facade of the Drum Tower, an iconic historic building in Central Beijing Oct.10. PM2.5(fine particles) concentration levels in Beijing have stayed above 250µg/m3 for more than 40 hours. The World Health Organization's guideline for 24-hour PM2.5 concentration is 25µg/m3. Greenpeace East Asia calls on the Chinese government to accelerate its efforts against air pollution, and reminds affected residents to use proper protection.[Yang Di / Greenpeace]
