Now you see it, now you don’t – the Beijing skyline disappearing act BeijingBill Bishop
We hear all the time about how bad pollution in China has gotten, but now we can really see it. Bill Bishop took photos of the same view in Beijing, looking out towards the giant China World Trade Center III on both a clear and a smoggy day. Shockingly, on a smoggy day the thick China pollution completely masks the behemoth building.
In this telling comparison of the Beijing skyline, it is evident that air pollution in China needs to be addressed. A common measurement of air pollution is the amount of particulate matter smaller than 2.5 micrometers (PM2.5) in a cubic meter of air. In the United States, the Environmental Protection Agency considers PM2.5 levels above 300 extremely unhealthy, all outdoor activity should be avoided. Beijing’s PM2.5 air pollution spends days at up to 500, and after weeks of a constant haze even Chinese state media are calling for action.
Keep an eye on your air.
