The Olympic Games start tomorrow, and though China has made concerted efforts to cut pollution down before the games begin, today the residents of Beijing woke up to a “white smog,” a phenomenon occurring when pollution is so thick that a skyline is virtually invisible.

How thick is a white smog, you ask? ABC (this is the Australian one, not the Disney one) puts it pretty well as such: “The smog is so thick that passers-by on the streets fail to cast shadows.” Gross. But if rain does hit Beijing tomorrow afternoon, as forecasted, the smog may dissipate prior to the Opening Ceremonies.

Way before this development, the pollution had already become such an issue some athletes had decided not to compete for health reasons. And this isn’t really helping any. At this point, though, it’s up to nature to hopefully lend a helping hand so that the events can proceed unhindered. As it’s not so likely you can take action to help unpollute Beijing before the Opening Ceremony, instead you can takepart here to see fifty ways you can reduce your own pollution output.
